That will get rid of the jitter that can happen on an imperfect sync then

dull kraken
#

Tested on dolphin and works like a charm

#

Adding field, linux saves frame to correct framebuffer always

shell prawn
#

When the protocol is updated, is there a way to track which version the MiSTer host is running?

#

I wouldn't mind having multiple versions of the protocol supported in the MiSTerCast app for people using it with potentially older Groovy_MiSTer versions

dull kraken
#

On log file, yes

shell prawn
#

or at least give an error

dull kraken
#

I think it's better do a major version for this

shell prawn
#

Sure, I just don't remember off the top of my head if I can fetch a version from the client to show the proper error

#

Often, I've run into people using mismatched MiSTerCast and Groovy_MiSTer versions

dull kraken
#

I understand, with old GroovyMister version i'm sure this fails

shell prawn
#

It would be nice if I could easily show an error to users on MiSTerCast if I could detect this

#

Maybe we could add a version indicator to the protocol as part of this breaking change?

dull kraken
#

It's a good idea, but i can't change older versions

shell prawn
#

Sure, but going forward

dull kraken
#

New versions are compatible with older protocols

shell prawn
#

Oh, I see what you mean, this isn't a breaking change yet

dull kraken
#

MiSTerCast is working with new cores

#

But a new MiSTerCast will not work with older cores

#

I can't break older protocols, so many people are happy with their installation

#

So, just with a new major MiSTerCast saying a september core version is requiered maybe enough

shell prawn
#

Yeah, I'll say it but I just won't be able to detect it at runtime

dull kraken
#

Yeah, i will need to add a response for future releases

shell prawn
#

If the version is a new packet only sent on request it wouldn't break older clients

dull kraken
#

It's a great idea

#

So response of cmd_init

#

Or just a new command to get version

I have a question. I saw the Groovy Dolphin @dull kraken you made and I was wondering if this concept could be expanded to other console emulators like Jzintv? Jzintv is a CLI emulator that allows launching Intellivision games from the command line. It supports JLP acceleration while the MiSTer FPGA core doesn't. Would it be possible to have some sort of .MRA files that actually send the PC the correct command to launch the corresponding game and stream it?

#

Like a sort of Jzintv Groovy

dull kraken
#

On every open source emulator is possible

#

With @lilac grove project will be possible init streaming as loading a core file

#

With Dolphin results I am satisfied so I will probably look at some other emulator, maybe pcsx2, flycast or else

mortal citrus
#

I'll eventually try this with the game Violent Storm.

echo dagger
#

Dolphin support is like magic!

dull kraken
#

@echo dagger Yesterday i fixed window output when isn't Groovy enabled and updated core for always match fields on interlaced frames

#

I played several hours and a lot of games and i think it's working really nice

#

There are some games like XenoCrisis forcing 240p output is better to me

dull kraken
#

@shell prawn I added a new command CMD_GET_VERSION 8. This returns a byte with number 1

#

So, now you can detect core version and decide which blit use

shell prawn
#

excellent, thank you!

I have some free time today and finally want to try out mistercast and groovy mister to watch some cartoons on my CRT. I'm a little confused by the setup though. My desktop PC is on wi-fi (500Mbps down and around 25Mbps up) can I run an ethernet cable from my PC into my Mister and use it that way or does it need to be hardwired to the router? I can't really run a cable to my router due to the layout of the place I'm renting

dull kraken
#

@ornate radish You can try wifi 5Ghz if have a good latency, ping less 1ms

#

But this wifi connected to MiSTer lan, not wifi usb

#

Although I clearly recommend the cable above all else

#

In preferent order: 1) direct connection PC - MiSTer, 2) router

ornate radish
#

Cool will be giving it a shot sometime today thank you!

ornate radish
#

Do I still need an unstable main or does this work on official main now?

dull kraken
#

You need to set main on MiSTer.ini

Thank you!

ornate radish
#

Got it working I don’t know why I thought it was more complicated. Now I need to mess with the settings to get the best mode lines. I’m getting some aliasing even on standard def dvd rips

random smelt
#

I thought about using one long cable to go router> Ethernet splitter/hub > two short cables to pc and mister, but I’m not sure it’d be any faster than two long cables from the router

#

I guess there are those dinky usb to Ethernet adaptors for laptops, no idea on the speed they can manage though

Whenever I try and set the Modeline preset to 640x480i I get error messages and mister cast crashes. Is this due to my setup? Desktop PC is wireless 5ghz and I have a Ethernet cable connected from my PC to my Mister

ornate radish
#

“Send command failed: 10035” is the error message I get

dull kraken
#

If you choose a lower resolution, i understand is working

ornate radish
#

Yeah works with the two non 480i versions just fine

dull kraken
#

Energy and transmit buffers

#

Seems last drivers of ethernet by default has power save energy

ornate radish
#

just checked for the newest drivers using automatic pull down and I was already on them. I turned off power saving as well. Still crashing at 640x480i. Any other suggestions?

#

now it's crashing even at 256x240. I guess I don't have the networking knowhow on what to troubleshoot

ornate radish
#

actually I never set up groovymame just mistercast and looking at the github for groovymame it asks to setup a static ip for the mister. Is this a required step for mistercast/would it help in this case?

#

I have Asus RT-AX86U Pro router but can't seem to locate the DHCP pool range

#

I also don't have this on my sd card

#

/etc/dhcpcd.conf

indigo swift
#

You can use the IP in the mister OSD where you change ini files. Just use that in the groovy mame config file

#

on the pc

#

IP might change, but it's pretty easy to just keep the config open in notepad++ and change it

ornate radish
#

currently I'm only interested in using mistercast. Was only looking up groovy mame as in the instructions it recommends getting that working first. I have my misters IP address in the target IP box on the mistercast application and it works but I can't seem to get it to be stable. I constantly get "Send command failed: 10035" and any resolution above 256x240 causes screen tearing and an eventual crash

#

but reading the groovymame instructions says my mister SD card should have an etc folder which I do not

#

not sure what else I can or should be doing though

#

The files I am currently using are: Groovy_20240910.rbf in the _Utility folder, MiSTer main dated 9/14/2024, and in my mister.ini I added

#

[Groovy]
main=MiSTer_groovy

ornate radish
#

Actually looking at the GitHub issues for mistercast issue 11 is exactly what is happening to me.

#

Try another ethernet cable. Make use it's gigabit. Try setting transmit buffers to 2048 in network adapter options. #1212527493169414266 message

ornate radish
#

I think I need to figure out a static ip or something. on the misc options screen on my mister only my wifi connection IP address is showing up, not a hardwire and a wifi. I should have two separate IP addresses showing if I'm understanding this correctly

#

I have tried two different gigabit ethernet cables so I'm guessing that has to be the culprit

#

also my ethernet status shows no internet access for IPv4 or IPv6 connectivity

#

I don't understand what I need to change on my PC for the gigabit ethernet cable connected to the motherboard on my PC to carry signal over to my mister. Sorry for all the questions but I'm at a loss since my Mister SD card is missing the filepath for /etc/dhcpcd.conf

#

"How to configure a Static IP on the MiSTer FPGA

Edit the /etc/dhcpcd.conf file on the MiSTer FPGA SDCard and add the below two lines at the end. Replace the <your_static_ip_here> text with the ip address you want to use on the MiSTer. This will set a static IP for the ethernet port, not Wifi.

interface eth0
static ip_address=<your_static_ip_here>/24"

Well shit. Doing this after pressing f9 and login: root nothing enters for password:
I tried pressing 1 on two different keyboards and other keys and nothing populates

#

Do I need to use ftp to add this?

#

Never have I felt so stupid

#

welp I think I'm gonna give up on this unless someone can spare the time to help me out. I cannot for the life of me figure out how to access the terminal so I can add a static IP. I usually am pretty smart with this kinda thing but I feel like a cromag

#

just tried putty as well and nothing will populate for password no matter what I press on my keyboard]

#

tried using winscp and was able to access my mister but in rootfs there is nothing

#

guh, like I said I feel so dumb. Someone PM me if you are willing to help

#

really wish there was another way to add static IP this is driving me mad

#

I'm not linux savy so maybe I am doing something wrong but all these instructions seem clear cut and I am getting nowhere

supple herald
#

You press 1 and hit enter

#

But yeah I usually use putty

#

Or keyboard direct on the rare occasion I have a kb plugged in

indigo swift
#

The Windows connection (wired) will not have internet access, but Windows should see it as a connected device in your network settings

#

The wired IP address Windows and the MiSTer share will be the one you want to point to with MiSTer Cast (I would think)

#

Try running 'ifconfig' from the MiSTer's bash terminal to see it's connections

Use 'ipconfig' with Windows cmd prompt to see what your PC is connected to

astral robin
#

@ornate radish the guide is misleading, I had the same issue where I couldn't locate the dhcpcd.conf file

#

Refer to my older message:

FIXED!

So today I got the intuition that something was off with the dhcpcd.conf file. I thought it was just too odd that the file and the etc folder weren't there... and indeed dhcpcd.conf is inside /etc/ (cd /etc/ upon logging in with PuTTY)

So I edited it using nano (fk vi btw) and appended the two lines. I used 192.168.2.1 to separate it from the WiFi range being 1.X in my case. Worked straight away

#

You need to configure a static IP on both ends

ornate radish
# supple herald Or keyboard direct on the rare occasion I have a kb plugged in

Putty I got nowhere. Entering 1 for the password did nothing. Direct keyboard into the mister after pressing f9, then typing root, and for password pressing 1 did nothing (as well as other keys) just kept getting failure messages. The only successful FTP I got to my mister was via winscp but even then anything within the rootfs folder does not show up

Fwiw i am not a putty fan, Git Bash is a really nice nix-like terminal emulator for Windows that supports openSSH key gen, SSH, SCP, Rsync etc.

#

Highly recommended for peeps that don't want to fuss with WSL2 linux

astral robin
ornate radish
#

I have not but I feel like I gotta get the mister static IP figured out first

#

I’m going to try and download the newest version of putty later and try again. If that doesn’t work I’m shelving this and will just use my dumb cheap av to hdmi pass through even though it looks like shit (and takes up more space)

Isn't there script for setting static ip?

Hey guys, I'm having some trouble getting the Groovy core to launch - I cannot see the bouncing ball and I cannot open the menu either. My mister is connected via Direct Video, and the only mister.ini setting I have changed is direct_video=1. All other cores have no issues with this setup. I've tried:

  • consumer CRT TV with SCART and multiformat BVM
  • fresh mister setup with mr fusion
  • various older groovy mister builds/mister binaries
  • using the mister.ini [Groovy] alternative binary method as well as directly replacing the mister binary
  • setting composite_sync=1
  • hooking out the output to an Extron RGB unit to see if it detects any signal (it does not)
    any suggestions for things I could try would be very appreciated! thanks!
tired portal
#

If that's the only INI edit you made, you are likely missing the other MiSTer binary file, and the INI setting to use it.

thank you, I'll check it out later when I can

#

Sorry, I'd not fully followed you likely did have the binary too. Hopefully working now

Jeebus filezilla

This happens like twice a week

tawny moss
dull kraken
#

great

#

I recommend winscp to avoid this binary issues

tawny moss
tired portal
#

No, my bad for not reading your post more carefully. Glad you got it all working. File transfer is often an issue.
Hope you enjoy some Groovy CRT content

supple herald
#

I don’t use filezilla but my understanding is that’s the default so it catches people using mister constantly, it’s not just you

#

Do the mister docs recommend or mention filezilla? Should probably have something in bold about it if so

tawny moss
#

no not in any official docs as far as I can see

#

it's just what I've personally been using for the last 15 years

#

and somehow didn't run into this issue (knowingly, at least) until now

supple herald
#

Yeah guess it’s just popular

#

WinSCP doesn’t have the same big name clout 😅

Neat, thanks

dull kraken

It is implemented on new build

severe geyser
#

Now Retroachievements is (kinda) doable on MiSTer

shell prawn
#

@dull kraken I started moving to the groovy API as part of this update. What's the blit delta?

dull kraken
#

Hi @shell prawn Good news!

#

Blit delta is sending blit by difference vs last frame

#

So if a new RGB value is (100,100,100) and the last one are the same, (0,0,0) are sended

#

This helps to compress frames

#

groovy API detects if delta frame is better than normal frame to send one or another

#

Here you find an example

hardy cryptBOT
# 
if (vid_mister_delta)
shell prawn
#

What exactly is matchDeltaBytes on the cmdBlit API then?

dull kraken
#

Every byte equal than last byte

#

Is an argument to help API to know if use blit delta

shell prawn
#

So it's something I need to compute?

#

Is it a mask?

dull kraken
#

8-bit overflow mask

#

Every value color 8-bit - last value

shell prawn
#

if I feed this 0 will it just assume everything is different?

dull kraken
#

yes

shell prawn
#

Okay, I'll start there 🙂

#

Thanks!

dull kraken
#

Better, blit delta is optional

shell prawn
#

I'll see about implementing it but I wonder if the additional CPU cost is worth it

dull kraken
#

With relative static images, the save is very considerable

#

Yes, needs a little more CPU

#

I implemented it thinking on 480p and upper

shell prawn
#

Oh yeah, I bet x86box benefits from this quite a bit

dull kraken
#

in my experience, 86box compress very well

#

vga images

shell prawn
#

I haven't tried it yet but I'm excited to. I think it's the only way to get native VGA from an x86 emulator that I know of.

#

Even the MiSTer core can't do it

dull kraken
#

altough now with arm clock +400mhz option or XDP server, raw 480p works as well

shell prawn
#

Oh, overclocking the ARM on MiSTer?

dull kraken
#

I'm using 86box on a CRT and it's incredible

#

Is a new core option

#

And it's safe

shell prawn
#

I haven't messed with XDP yet but I saw the information on the core README

dull kraken
#

I recommend XDP for sure

shell prawn
#

I want to test everything with the default setup first since many will use that at first.

dull kraken
#

I understand people don't use it because you need replace kernel file

shell prawn
#

Yeah, I imagine it greatly reduces usage

dull kraken
#

I needed to build kernel with some patches and XDP

#

XDP increase performance a lot

shell prawn
#

and I assume every MiSTer linux update replaced it again

dull kraken
#

yes but kernel is very stable

#

very few updates

#

I tunned for better performance, with vanilla kernel some driver params are not good enough

supple herald
#

Any chance it could be incorporated by sorg?

dull kraken
#

Nops

#

Sorg isn't interested on network patches

#

It would only happen if the kernel is updated

#

Now is 5.15

#

from 5.15 to nowadays exists a lot of increment XDP changes on kernel and driver

#

Actual vanilla kernel is using 64 packets napi polling, with XDP i set to 1 so latency is negligible

shell prawn
#

The first attempt wasn't a success but hey there's some of my desktop there 🙃

PXL_20240924_143259667.MP.jpg
#

Oh wait, I think I need to update the core already

dull kraken
#

yes, MiSTer_main and rbf

#

here you have an example if you want use switchres lib

hardy cryptBOT
# 
if (vid_mister)
shell prawn
#

Currently getting black video on the new client with the new core but old client with old core is fine so I'll have to debug later.

#

Most my code is the same but I'm calling the GroovyMiSTer APIs instead of doing my own networking.

dull kraken
#

Try with progressive modes first. With interlaced you need to get buffer with field

shell prawn
#

Yeah, that's what I did but without much luck. Video isn't syncing with my CRT so I'll have to look into it further.

#

switch res command is the same as before

dull kraken
#

If you run core with verbose 1 attach log to see what happens

shell prawn
#

Yeah, where does the log dump to again?

dull kraken
#

/tmp

#

After set 1, save settings and reload core

#

recv=0/11175 means it's not getting the frame data?

#

I'll have to look into CmdBlit to make sure it's sending

dull kraken
#

Udp error means some length isn’t expected

#

Maybe we need verbose 2

#

Ahh wait

#

1472 is the length expected

#

What mtu are you passing?

#

1500 is minium

shell prawn
#

Oops, I was using 1472

dull kraken
#

1500 or 3800 for jumbo

shell prawn
#

Which was the max we found works best?

#

okay, will do 1500

dull kraken
#

Api subtract udp header

shell prawn
#

yep that was it

#

Yeah, I had that constant because I was look at just the user data size

dull kraken
#

I choose 1500 because is the number ifconfig reports

shell prawn
#

When is it recommended to call WaitForSync in the flow? Right before or after calling CmdBlit?

#

I'm trying to remove the timing code I have from the old retroarch code.

dull kraken
#

Always after cmdblit

#

This will sync with crt raster

dull kraken
#

Before cmdblit, calamity developed a formula to get which field is waiting for

hardy cryptBOT
# 
int MiSTer::getField(void)
shell prawn
#

Ah, I was using the same mechanism for field

#

Should I upload audio after SyncWait?

dull kraken
#

Preferable audio before cmdblit

shell prawn
#

Okay, going to move that then

#

I was doing it after for some reason

#

but my wait logic was a bit different before

#

Didn't get a chance to mess with it after the MTU fix

dull kraken
#

If you send after it, will work but fpga pause blit to get audio first

#

For core, cmdaudio is like hard irq

shell prawn
#

Okay, going to send it even before processing the video then

#

give it some room

dull kraken
#

So change the context to write audio first

#

You cannot send audio and video on different threads

shell prawn
#

They're on the same thread

dull kraken
#

Udp packets mix

#

Ok

shell prawn
#

I was doing

Process Video
CmdBlit
Process Audio
CmdAudio
WaitSync

#

so just moving Processing Audio and CmdAudio to the beginning of the flow

dull kraken
#

Is a little better, yes

#

Send audio will be 0.0x ms

#

Maybe process all first and send all

#

Process audio and video

#

Cmdaudio and cmdblit

#

Because you don't want a delay between audio and video

#

Btw, i will add a cmd to set or get any core option. Could be interesting for example to set audio on remotely

shell prawn
#

Yeah, that would be great because it's been an issue a few times with users

dull kraken
#

Yes, will be easy to do

shell prawn
#

if I want to use auto sync delay (no vCountSync) with CmdBlit, is a margin recommended?

dull kraken
#

15000 it's a good value

#

this will absorb some jittery

shell prawn
#

Still having a bit of stuttering. Looking at the logs I see LZ4 info=0

[00.017][GET_STATUS][DDR fr=2 bl=0][GPU fr=0 vc=241 fskip=0 vb=1 fd=0][VRAM px=0 queue=0 sync=1 free=1 eof=0][AUDIO=1][LZ4 inf=0]```
#

I was passing 1 for LZ4 on init

#

In my own code I was using LZ4_compress_fast_continue before switching to the API

dull kraken
#

Do you have complet log?

shell prawn
#

Yeah, I can DM it but it was only verbosity 3

dull kraken
#

Just few lines with blitting frame 1 or 2

gloomy slate
#

@shell prawn Have you tried running mistercast without lz4 compression? Bandwidth is high but groovy retroarch and dolphin stream to mister is much smoother without compression for my setup. Output to mister can get choppy with lz4 turned on while smooth on pc side.

#

Also any chance of adding window capture and capture screen padding for adjusting aspect ratio and overscan?

shell prawn
#

Yeah, I do want to add the window capture and passing options

severe geyser
#

For some reason joypad inputs aren't coming through to GroovyRetroarch

#

Dunno if to do with new settings

#

MAME is same, looks like inputs just aren't coming in for some reason

severe geyser
dull kraken
#

I don't have issues with input controls. Do you tested groovymame changing joystickprovider?

#

To test if main detects joysticks, with verbose log 2 is possible to check /tmp/groovy.log when button is pressed

#

Ofc, before that you need to enable input controls on core settings

#

just in case check the windows firewall that it is not blocking something

severe geyser
dull kraken
#

Joysticks: Digital

#

PS2 is for keyboard and mice

severe geyser
#

Huh, after saving settings it works now while I tried to do logging

#

Though I guess it asks to reset to save the changes but that was greyed out so I didn't see it

#

@dull kraken

Sorry for inconvenience

dull kraken
#

Perfect

lost star
#

Why is my audio so bad on mistercast? Is there a fix for this? Everything is amazing otherwise

dull kraken
#

Probably because your audio device is set to 44.1khz and actual core has a bug with this rate freq

#

Try this one with sound fixed (use with last groovy mister main)

lost star
#

Thank you sir.

#

I'm also having issues with audio on mistercast, but the audio from groovymame is completely fine. The audio coming from mistercast sounds unrecognizable from the original audio, not just poor quality. Audio device is set to 48khz and I've tried the groovy.rbf linked above. Anyone have any ideas?

shell prawn
shell prawn
#

Oh, it looks like Y/C does work but just not in 480i for some reason

#

320x480i works fine but 640x480i is black and white

winter wadi
shell prawn
#

oooh yeah that makes sense. I should pop a warning for that

#

I could try to recreate the 2 channels but I worry about how many possible audio configurations there are and I'm not setup to test anything more than stereo

severe geyser
#

Trying to use Analog Mode with Dualshock 3 seems pretty finicky for the control sticks in Retroarch

The inputs for them seems bit poorly calibrated when trying to apply the analog directions

Atm I'm testing Duckstation

#

But even in input configuration for RA, the analog input registration has this issue where the dead zone seems way too big to a point the input gets lost of I move the sticks too far from the center

Hello,

Wondering if I can get some assistance with Mister Cast please.

To preface, Groovy Mame works fine without these problems. As well as two Displays, one CRT TV connected Via Analogue Out and one CRT Monitor Connected Via Digital (w/ vga adapter) Out

I'm running into a couple of issues.

The first is while streaming video only on Mister Cast both of my displays have really Bad sporadic tearing as can be seen in the video and one set of pictures.

The other issue has to do with the colours. The CRT Monitor looks as it should, however the CRT TV has this Red and Blue thing going on in darker areas. This only happens with Mister Cast.

Any assistance would be greatly appreciated. If any more information is needed to help with determining a possible solution please don't hesitate to ask.

Very Respectfully

Hi everyone, I have some very sad news to share. My brother Psakhis has passed away. It's a really difficult time for me and my family right now but I wanted to let you all know since he loved to explain me this project and i knew he loved this. It was one of his mains hobbies. This and biking. He was very strong climber, we did many rides and climbs together but unfortunately he had a heart condition that ultimately ended his life. Thank you for understanding, and I appreciate your support during this time.

Sure, no problem. It has been so sudden, its still almost impossible to accept for us that this happened. I wanted people involved with him on this project to know what happen because sadly he will not be here again with you working with this lovely project that he dedicated so much time and love. Everything he did , he did with dedication and passion and he always reached impressive results.

#

You dont know how many times when we were riding he was talking about the problems he was facing with this work, im happy i was able to give him some ideas (specially on network management and some basic ideas). He was the one who actually got me into software programming, not just my brother, my best friend

Psakhis will really be missed, I knew him from the GroovyArcade Discord. He helped me with many things and convinced me to buy a MiSTer. Boy did I not regret that. His GroovyMiSTer project is also really awesome. I'm very sorry for his loss, my condolences.

Heavy condolences here from Sweden, his work is not even fully realized by a lot of people, it will make a big mark in history of the MiSTer project. It fills a huge gap making games playable on a arcade machine with just one MiSTer setup, rather than needing another MAME setup along side it.
Most people here realize this already, and I will make sure more people get to know about his work.
I will dedicate my next stream to Psakhis, hoping some more people will know about what he accomplished ❤️

Deeply devastated of hearing these news... I'm so sorry for your loss @lean tulip.

Psakhis's project really helped bridge the two sides of current retro gaming so incredibly well and even then some, especially for us CRT-afficianados.
It's thanks to him that I've been able to revisit achievement gaming on RA again but from the provided comforts and stability of MiSTer. Made me wonder what new ideas he could have come up with.

I'm really gonna miss him - but I can't imagine how huge the grief is on you and rest of family. May you find peace and I want all of you to know how much he meant to all of us.

Yeah I heard about it mid stream and had to take a moment to raise a glass to him. It was a moment.

Now that I have an analog io, I've been trying to get this working, but I'm having a couple of issues. I had an ethernet connected directly between the pc and the mister, with the mister set to a static IP and both devices also having wifi. I could get it to run, following the instructions on the groovymister/caster github's and installing mame as per Calamity's instructions here: https://misterfpga.org/viewtopic.php?p=87802#p87802. I receive casts/mame, however:

  • There was a lot of stuttering and graphical glitches with both mame and caster. It would often become worse over time and eventually crash. After a lot of trial and error, I think I've determined it's trying to send the signal over wifi, despite the ethernet connection. For example, if i unplug the mister's wifi dongle, I can no longer get groovy to load the bouncing ball/connect to the pc, and caster fails. I'm not sure of a way to ignore the wifi connection, and I don't know why it won't transmit over the direct ethernet. I've tried a couple of different cables, and my PC sees the connection, but something is getting in groovy's way. I may try running two long ethernet cables to the router tomorrow and see if that helps, but I'd love to use a shorter cable directly if I can.

  • Mister sending input back to the pc mame application is weirdly hit or miss. I have a fightstick with ps4/ps5/xinput options; mister seems to only see it in ps4/5 modes for some reasons. I've got it configured in the mister osd, and set mame specific controls in the core. It wasn't working at all on mame for a while, but while working on the problem above it started working again. Now it's back to ignoring the input. No guesses here yet; the option for joystick is set on to digital. Another controller (a playstation controller) is currectly working in mister and sending signal to mame, the fightstick works in mister but is ignored by mame.

I found this exchange and tried setting static ip on the pc as well, but it hasn't made a difference for me:
tamagokun — 9/19/2024 12:25 PM
disabled wifi on mister, and on rpi, plugged rpi directly into mister. no dice at all. mister has a static ip set. I must be missing something to set this up properly

Calamity — 9/19/2024 12:30 PM
You have to disable dhcp on the rpi and set a static ip there too, otherwise the rpi won't get an ip.

tamagokun — 9/19/2024 1:01 PM
sweeet that did it. thank you!

random smelt
#

As an update if anyone finds this, connecting two separate cables to the router did fix all of my groovy/caster image and glitching issues. Works well now. I have no idea why I can't get a direct cable solution to work, fixed IP didn't help. I have to assume Windows blocked the transfer with some settings, but even disabling firewall didn't help.

#

Still no luck getting the fightstick to consistently send inputs back to Mame from mister, so I've been leaving it connected to the Mame pc for now.

#

Is shutting off the monitor causing mistercast to break expected behavior? I was expecting to not play it on two screens simultaneously, but it seems without the pc monitor the stream breaks. It's connected by displayport, I assume it's sending some message back to the pc when it shuts off.

severe geyser
random smelt
#

I hadn't properly set the static IP, it seemed.

#

plus Kayster's tip that the config file was in /etc/ instead

#

I had set the static ip on my router and thought that would handle it, since my mister on wifi had been static for a while. I don't know anything about networking so I didn't know to also set it internally on the mister, or how to set the static address for the ethernet cable on the windows side.

#

Do we have a good place to put some notes for when more dummies like me try to do direct connections in the future?

Looks like it's an issue with OpenGL or Vulcan specifically - they create screen tear for me for some reason

So just testing out mistercast and groovy for the first time with my PVM.

When using any 480i (240p seems fine) resolutions in mistercast I'm getting a garbled image in the lower half, of the image, aswell as some ocational freezes.

Just before I start to move crts around. I assume this is a bandwidth issue?, I have my PVM in another room than my desktop PC and router, and don't have a long enough tp-cable to plug in to the mister, so I used WiFi in the mister end.

#

Hard to capture, but it is seen in the lower part here.

supple herald
#

I think there were some fixes related to ordering of interlaced fields, I’m not sure if that was in the groovy_mister before his death or not. But yeah almost all groovy issues are bandwidth so it wouldn’t hurt to go down that road before bugging Shane or something

Trying to use Analog Mode with Dualshock 3 seems pretty finicky for the control sticks in Retroarch

The inputs for them seems bit poorly calibrated when trying to apply the analog directions

The analog input registration has this issue where the dead zone seems way too big to a point the input gets lost of I move the sticks too far from the center

#

I've been trying to move the use of analog sticks to DInput on my PC via (Dualshock 3 with DSHiDMini) to make up for this issue but unfortunately it introduces input lag

#

I wanted to talk about this issue before but since Phaksis had passed away last year, it didn't really make sense to do so for indefinite time

Also on this issue, I read that it might be due a resolution mismatch, but I can't seem to figure out a way to fix it in GroovyRetroarch

So in order to get the CD-i core to work I updated to the latest unstable build, now I am trying to get groovymister to work as well, but for that I need to overwrite the MiSTer file. When I try to do that, my device no longer boots. Is there a way to get both to work at the same time?

#

(simply booting the groovy mister core without overwriting the MiSTer file just gets me a black screen, core menu still works but I don't see the bouncing ball thing I think I'm supposed to be seeing)

oh thanks, didn't know you could do that for cores as well

still didn't work for me sadly, core crashes when i try to load it, maybe that particular MiSTer file doesn't work with the nightly build i updated to?

indigo swift
#

just copy that into /media/fat where your other main and ini files are, and make sure the line in the .ini matches the file name

No I did that but same thing

Maybe it doesn't play nice with analog IO? or i might need to configure other settings specifically for the groovy core?

I finally was able to get Groovy running, a lot of the video tutorials you find online seem to be a bit outdated so I'll put together a quick one here:

First, go here and click the last build on the list (currently 20240922): https://github.com/psakhis/Groovy_MiSTer/tree/main/test-builds

Inside the folder, download the MiSTer_groovy and Groovy_20240922.rbf files, nothing else.

Now, plug in the microSD card you use on your MiSTer into your computer. You're going to go into the main directory of the microSD card and you're going to drop the MiSTer_groovy file in there. Don't change anything to the file name (no .bak, none of that), just drop it in the main directory. Once you've done that, go into the _Utility folder and drop the Groovy_20240922.rbf file you downloaded earlier in there.

Go back to the main directory and right-click the MiSTer.ini file. Click 'Edit in Notepad'. At the end of the file, make sure to add the following:

[Groovy]
main=MiSTer_groovy

Save & close. You won't need to be going in there anymore. Put card back in MiSTer.

Next, download the latest version of GroovyMAME from here (currently 0.277): https://github.com/antonioginer/GroovyMAME/releases

These will be the .7z file for the latest GroovyMAME version and the mame_mister.ini file. This mame_mister.ini file will end up getting renamed to mame.ini (you can do this as soon as you download it, just leave it on your desktop for now).

Extract the folder from the .7z file to where you can easily find it i.e. desktop and drop the mame_mister.ini file in the main directory of this new Groovy folder (make sure you rename the file to mame.ini first, then drop it in there and you'll be prompted to replace the file, choose this option).

Once you've dropped the new mame.ini folder into the Groovy directory, right click it and pick 'Edit in Notepad'. There should be a note with some instructions pertaining to the mister_ip, follow them. Get the IP address on your MiSTer and enter it there.

cunning light
#

While you're there, make sure that your rompath is set to roms (this indicates the folder you'll drop your rom files in). Usually it's set to roms by default, so not much to change or worry about there.

Save & Close.

In the Groovy directory you'll find a mame.exe file, right click it and pick 'Create a Shortcut'. Once you see the shortcut created, right click it and click 'Properties'. If you don't see that, you night need to click 'Show more options' first.

Once you're in the Shortcut's properties, where it says Target, enter the following next to the words mame.exe (skip a space, don't attach them together): -video mister -aspect 4:3 -switchres -monitor arcade_15 -mister_window -mister_ip "192.x.x.x" -mister_compression lz4 -skip_gameinfo -syncrefresh -nothrottle -nomister_interlaced_fb -joystickprovider mister -keyboardprovider mister -mouseprovider mister

A lot of people mention that they can't enter everything above as it won't fit. This is why I recommend changing the Groovy folder name to 'GM', as shortening the folder name will give you more characters to fit into the Target. Not everything may fit, and I recommend putting everything up to -joystickprovider mister, at the very least. There's other ways around this to add more characters, but let's keep things simple.

In the section where you see -mister_ip, make sure to enter the same IP Address you entered in the mame.ini file from earlier (or just turn on your MiSTer and check from there). It should look like this when you're done: mame.exe -video mister -aspect 4:3 -switchres -monitor arcade_15 -mister_window -mister_ip "XXX.XXX.XXX.XXX" -mister_compression lz4 -skip_gameinfo -syncrefresh -nothrottle -nomister_interlaced_fb -joystickprovider mister

Click 'Apply', then 'OK'. You should be all set. In the GM directory, go into the roms folder and drop your roms there now.

#

Connect your PC and your MiSTer device to the same network (wired preferable). Open the mame.exe shortcut you created, let it load. If you did everything correctly, the game screen will appear in the top left corner.

Now, turn on your MiSTer. Make sure it has connected to your network before proceeding.

Go into Utility and pick Groovy. If you did everything correctly, you should see the bouncing logo. Make sure to go into the OSD on MiSTer and configure your audio and your Joystick/PS2.

SAVE YOUR SETTINGS!

Configure GM on the PC as you wish. There are ways to control the Groovy menu from the MiSTer, so I'll let you guys figure that out. Run your game on the PC and it should now display on your CRT through your MiSTer device.

Have fun.

Hey guys, I'm trying to get a solution to use retroachievements through my CRT and decided on using a mister. Would I find a better experience using Mister cast and streaming my PC running Retroarch or using the Groovy retroarch core?

Groovy

#

Will be lower latency and you can use controllers hooked to the mister

MisterCast will add like a frame or two of lag

Did you set input_driver and input_joypad_driver in the retroarch.cfg?

robust kindle
#

I have no controls also in retroarch 1.19.1, with the cfg set to "mister" also :/ No keyboard, mouse or USB controllers work. The video is working good tho. I tried setting the controller in the core menu also but that didn't help.

robust kindle
#

If I set PS/2 to Keyboard, the enter key seems to work with the core, but all others don't. Remapping/assigning keys or joystick (digital) all seem to do nothing :/
My controller does work in GroovyMame (via groovyMiSTer) though so perhaps it is a retroarch configuration issue?

robust kindle
#

ok figured it out @fair lance .
I got groovymame and flycast working with controllers first to make sure mister end was setup correctly. Then in retroarch, you need to set input_driver to get the keyboard working. Also in the cfg, you need to set all the input_player1* input_player2* controls to not be "nul". I found that out when trying out some of the .cfgs posted in this channel earlier.
eg:
input_player1_down = "down"
input_player1_down_axis = "nul"
input_player1_down_btn = "5"

Finally, my 2 controllers were mapped to player 1. To fix I needed to change input_player2_joypad_index from 0 -> 1

#

the default retroarch.cfg has all of this as "nul" which threw me off (also no controller mapping options in the menus)

fair lance
robust kindle
#

sure here you go. This is mapped for flycast using my retrobit controller for testing. I'll have to setup remap files for the cores.

#

Yeah 240p content runs really well, but 480 is too laggy at the moment for me. I had to use force_rgb565 and lz4 mode 3 to get the more frame intensive stuff to even run properly without artifacts. I haven't had any luck with large blocks and mtu setup, once I bump that up the emulators slow down to a crawl and are unusable. will have to investigate what is going on there

Cool video. Reminds me I never did test if setting static IP on PC and MiSTer would let it work without any internet connection and just a direct ethernet port.
I remember trying that once but being confuded by the lack of any IP address showing up on MiSTer at all if both devices are offline, just connected to each other

I’ll need to check out this new video. I was never able to setup a static IP on my mister for GroovyMister but maybe I was missing a step

It shows a way to do it with a keyboard connected to MiSTer. Probably the easiest way for the clueless user (i.e. ME). With the static IP working I've finally got mine to connect without either device on the internet. Direct ethernet lets go!

Any advice to get the highest resolution out of Groovy MiSTer?
I'm fine for 240p, but 480i and I'll have hitching video glitches.

Got a wired ethernet direct from MiSTer to PC. Both on static IP addresses. Tried multiple ethernet cables (I did have one bad one historically so I know that can be the culprit!).

Any advice on the Groovy core settings? I'm not really sure what "Volatile Framebuffer", "Verbose" or "Blit at" should be on.... Currently; Off, Off and ASAP repsectively. I've tried a few permutations on those but not really sure

I wasnt able to get 480i working reliably either, unless the frame deltas were minimal. But full 3d content hitched too much for me unfortunately

I ended up finding your post above shortly after my ask. Can you elaborate on what assigning the player inputs entails? I read your comment above as well about some of them stating "null", i'm just lost as to what one's I should be changing, and what I should be changing them to? The log file your config generates in the bg shows that it's recognizing the mister input drivers and auto-config'ing the controllers, just not getting any action, assuming because of what you're explaining. EDIT: Figured it out, murphy's law just demanded that I repeat the same process 50 times until it worked lol... Btw, this is fantastic so far!!!

robust kindle
#

Ah sorry for delay, sounds like you got it! Yeah you need to set the values to match the mister side config (from the menu inside groovymister core)
Eg: input_player1_y_btn = "9"

You will need to experiment a bit depending on your controller and the retroarch core you are using. After that works, you can use retroarch to overwrite specific core/roms. Glad you got it working!

Can someone try this with HDMI? Does it improve the latency and frame rate stability?

indigo swift
#

This was built specifically for CRTs. Lowest lag over HDMI would be a direct connection to a display. Then it depends on how much inherent lag the TV or monitor has. And if a TV ensuring Gamer mode is on, or any video processing settings that could introduce lag are turned off.

Just curious as someone with recent success, have you managed to send stable 480i over?
This was me struggling with MiSTerCast on that front. Not sure if the likes of mame would tend to be higher res

marsh phoenix
#

think everything was okay on the games side of it though...

tired portal
#

Cool. Yeah, pretty similar. I guess perhaps 480i stable being an issue might be common. Perhaps I am mistaken thinking people had worked out a way to get 480i stable.....

marsh phoenix
#

my thoughts are, some sort of settings boost option, I just don't know what that would be

#

it's acting like info is getting bottlenecked

marsh phoenix
#

has anyone that's using Retroarch with this setup, found a way to fix the bug w/ RA that basically "force-fucks" up your TATE mode in some games, to only display TATE-upside down, and any other setting you change it to stays exactly the same? It's not all games luckily but certain games, Frogger for example, just refuses to TATE the proper direction. I'd have to flip my TATE tv to get it to work (which isn't happening with this 27 incher)

#

I've been all over the place with this issue, trying every variation of config file setting I can alter, and i'm getting nowhere... Wondering if it's more something to do with how switchres is handling or receiving setting info?..

Controllers should work through mister. 480p output max but internal render can be higher.

# gloomy slate Oh, here are the files. Forgot you need to login to the forum to get the files. ...

Thanks!!! I set it up yesterday and it works like a charm! I tested CRT and OLED TV. Perfect on CRT. For OLED, there seems to be no deinterlacing filter (which makes sense because it was built for CRT) but I guess there should be a way to implement one like what we have on the PSX and saturn cores. I may have a look, that would be a cool project to learn how to work with FPGA cores (if I can modify this core, I am not sure about that...). So, outside of retroarch, there is a groovy branch for Mame, flycast and dolphin, but not for PCSX2, right?

Oh mistercast doesn't support mister input so need to connect controllers to pc.

Dolphin and ra have progressive options. For ra I think you need to set mister_interlace_fb to false. Mister_scanlines might also need to be set to false. Mistercast doesn't come with 480p modeline so you need to make one (I can't help with that heh.)

tired portal
#

Is there a latency difference? Is MiSTer input just useful for convenience depending on setup?

#

I've the MiSTer and CRT beside the PC. I know the way the video renders can make the native Groovy supports really good on video latency.
If PC is doing the emulating, does it make a difference which of PC/MiSTer is used for controllers?

gloomy slate
#

I'd definitely like to see someone test that

marsh phoenix

Could see if there's a firmware update for the adapter?

Otherwise, try some of the other options if you can. At least it seems there are ways, and the limitations are almost surely down to these aspects. Forget the word

Yeah, this setup is probably ten plus years outdated, was lucky to get a win10 install on it few years ago. My cousin salvaged it from a recycling center... I'll try to update the driver or check for a firmware update, I might also just look into a semi cheap ethernet card since I got one extra slot I can tap into

Can be a hard one to debug. Be good to get it working so it could be added to a helps and tips document some day

#

Not seeing the network when both pc and MiSTer are only connected wired to each other was an issue I had too.
Have you tried the direct connection again after setting the static IP on MiSTer?
IIRC when I set MiSTer, even when it only had wired ethernet to the PC the MiSTer would then display that static IP address and MiSTerCast let me connect

#

When testing what output are you selecting for MiSTerCast, that could be it

#

Always test at first using the very lowest resolution option. If you can get it working, you might still need other changes to improve the pass through of data to get 480i working say. Just getting something at first is all you'd need to start

quiet ginkgo
#

I tested all resolutions and none of them worked for me

#

And i tried to follow the tutorials to set it up

#

I was just wondering if i was misunderstanding something because it looks so simple for everyone else when watching the setups

tired portal
#

Not as simple as it seems at first glance, I'd say that much

#

Simple if it all works first time, but lots of little things that can go wrong

Did you see an IP address on MiSTer on the MiSTer menu when it was direct connected to the PC?

#

Not an ancient PC either....?

first it was getting Network to jive, next day it was fighting the controller setup, and day after it was dealing with Retroarch and it's mind-boggling handling of game aspect ratio's across 3 different config files

if it was me, I'd maybe suggest try to groovy mame working first, then move onto RA, and Mistercast

#

I originally was fighting with RA to get it to work for probably day n' a half, then i kinda put that on hold, and decided to try setting up Groovy mame first. I got that working, and it made me a believer, then mysteriously RA worked for me next morning

#

I'm pretty sure I was fighting off some invisible tech goblins thru my whole setup. It was a spiritual experience/battle lol

Just to be sure. Has anyone here been able to use analog sticks in retroarch (controller pluged in MiSTer) using Groovy? Everything works for me except this. What is even more puzzling is that in the input menu of retroarch I can bind the stick (it recognise them) but the analog stick do not work in the cores I tried....

glass zealot
#

I reinstalled everything and still get the same issue with the analog sticks.... I am a bit lost here. I use a DualSense if anyone what to try on their side.

fair lance
# glass zealot OK, just tried this. As expected it only make the analog stick acting like the d...

I think it does not work with retroarch because the analogue sticks cant be mapped as separated/alternative buttons from the dpad on MisterGroovy menu on Mister. You can only map the dpad or the analogue as right, left, up and down. Or the analogue like the dpad/or dpad as analogue. If not mapped as a button in groovy menu, It is not recognized as a button for retroarch to be mapped/used. For me It does not work either.

#

Also, dont think there are many games worth emulating in this setup, that use both dpad and analogue. PS2 and GameCube amulation on retroarch is not ideal.

glass zealot
tired portal
#

There should be a fix method hopefully for people more knowledgeable that can chip in. Main thing as you say, you don't ever maps analog sticks in any core. If any of the other applications like flycast works, then we know the core is getting the sticks data on MiSTer side

glass zealot
#

in mister_joypad.c in this function: ```static int16_t mister_joypad_axis_state(
mister_joypad_t *pad,
unsigned port, uint32_t joyaxis)
{
if (AXIS_NEG_GET(joyaxis) < pad->num_axes)
{
return ((pad->axis[AXIS_NEG_GET(joyaxis)] << 8) + pad->axis[AXIS_NEG_GET(joyaxis)]);
//RARCH_LOG("[MiSTer] joyaxis neg %d...\n", AXIS_NEG_GET(joyaxis));
}
else if (AXIS_POS_GET(joyaxis) < pad->num_axes)

return ((pad->axis[AXIS_POS_GET(joyaxis)] << 8) + pad->axis[AXIS_POS_GET(joyaxis)]);

return 0;

} ``` the lines return ((pad->axis[AXIS_NEG_GET(joyaxis)] << 8) + pad->axis[AXIS_NEG_GET(joyaxis)]); and return ((pad->axis[AXIS_POS_GET(joyaxis)] << 8) + pad->axis[AXIS_POS_GET(joyaxis)]); are puzzling to me. Does anyone more knowledgeable can say why is in not simply return pad->axis[AXIS_NEG_GET(joyaxis)]; and pad->axis[AXIS_POS_GET(joyaxis)]; ???

Yeah, my default values that were chooseable out the gate on my realtek, had one maxxed out at 128, the other one maxxed at 512. I changed both in the registry to something higher (I think I did 2048 on both). The setting shows that it stuck and it's in the dropdown, not sure it actually changed it though on mine. Didn't really make a huge noticeable difference. Mine had 4 RSS queues setup by default though. (haven't tried adding more yet, gotta double check my core count on my pc)

#

My setup still works quite well though I should say. Only bits of semi-major stuttering I find is in a few Flycast titles, but even those I've been able to tweak settings to be playable

#

RA and Groovy mame are pretty much 100% cross the board for me. (minus the titles each emulator might struggle with on their own already)

That's more or less what I feel like is going on with mine. I haven't had enough of a problem with many games, so I pretty much have just left it for now. Only stuttering I see for the most part is in a few flycast games, especially the more 3d rendering titles like Wild Racers and King of Route 66. In your experience would it be the network adapter itself that is capped at those transfer buffer rates, or the motherboard of the PC? I still may try another network card at some point just to see if I can get it to improve a little bit.

glass zealot

in the case of the Intel card I mentioned, just a matter of win11 drivers missing the settings that the inf files are meant to add compared to their win10 equivalent

I'm finally getting around to installing groovymister for the first time, and I thought I followed all the directions, but I just get a black screen from the mister end (and nothing from the GMame end, which I sort of expected).

#

so I installed the two files on the mister and can launch groovymister. I replaced mame.ini with the groovy version and changed the mister IP.

#

I threw my legally acquired ROM file into the roms folder, and launched groovymame from the command line, it didn't give me any errors, but the mister hasn't done anything.

#

What am I missing?

#

OK now I'm getting ... sounds like scrambled game sounds, but the PC end is at least making noise.

#

OK, the game sounds start (at 800% speed) after I wiggle the joystick to clear the standard MAME screens (which I can't see)

#

so controller inputs are the only thing being shared between the mister and the PC, there's no audio or video coming out on the mister end

#

According to the display on the irken jamma expander, the video signal is 10.7kHz where I kinda want 15kHz

#

so that's a problem, not sure how to sort that out.

empty fulcrum
#

Is it because I'm using direct video=1 maybe?

young hull
#

Maybe, couldn't hurt to toggle that off and see

Still beavering away at this. A lot of instructions talk about replacing the MiSTer file, but it seems like that's now adding MiSTer_groovy, and adding the [Groovy] config to the MiSTer.ini file.

#

When I launch the _Utility/MiSTer_Groovy from the MiSTer, my screen goes blank and it totally stops responding to the keyboard, I'm not sure if that's relevant or not.

#

But I've triple checked everything and it still runs at max speed (not 100%, but like 1200%) with no video on either end. The speed and everything in the MiSTer.ini is all 1, frameskip 0, etc. I have no idea why it's running so fast.

empty fulcrum
#

OK so I plugged the HDMI into a TV and as soon as I launch groovy on the mister the TV loses the signal.

You should see a bouncing ball when you load up groovy on mister

I use WinSCP

which does it by default (I just checked).

You have to use the one that works with groovy and use that alt main feature in the ini

So either the config line in the .ini is not being picked up.

I think I renamed the RBF for simplicity

MiSTer_groovy.rbf is what I called it

and the sound still comes from the PC, is that right?

woeful notch
#

it can come from the mister

empty fulcrum

does that need to be configured separately?

#

and every time focus is not on MAME, the speed rockets up again

OK so audio and inputs remain, but I've got perfect video. ^__^

you have to enable sound in the audio section in the mister core

What's the mister core in this context? Keeping in mind that I have sound with all my other cores.

for inputs, you need to define groovy buttons (in the menu that comes up when you press right on the main mister menu), and set server -> joysticks to Analog

All my sticks are digital

but yeah they're all OFF by default, keyboard too

that's probably something that could go in the docs, along with turning on the sound

I use batch files on the PC (launching games with the respective groovy software) and SH scripts on MiSTer (starting MiSTer Groovy and respective batch file using ssh) to launch games on the MiSTer without having to touch my PC. Following suggestions by Zakk I also created MGL files and a special script to launch these SH scripts as if they were any classic MGL files (meaning I can also get them working with attract mode...). My idea is to centralise my retrogaming experience on the MiSter, even when playing games running on emulators on my PC. If this is of any interest I can share the principles at some point...

#

That said if you just want to press buttons on your controller to use as credit/start on groovy mame I do not see why this would not be possible? In groovy (MiSTer side) you can assign specific buttons to your controller (from 1 to 10 I think). Then in Groovy Mame I guess you just need to make sure the button numbers you want assigned to credit start match the layout you choose. I guess. I haven't tried Groovy Mame yet, just worked with Retroarch and Flycast for now...

# empty fulcrum I would be very interested in this. 🙂

OK, I'll post templates with an explanation of how to use this week-end if I find enough time. I do not know yet how to make it work with mame but I am pretty sure there should be an easy way (I just have not looked at it yet...)

marsh phoenix
#

@empty fulcrum I've had some tidbits floating around in my head since going pretty deep into this, I thought might be worthy of a share (these are just things I picked up from others scouring the forums and discord and while I was working with troubleshooting and dialing in my own setup)

#

I put them into text yesterday, I by no means am an expert with this info (feel free to correct me if need be on any of this). I'm still learning about all of this myself.

#

but thought I'd add these tidbits into the ether (feel free to verify and use in your guide if you wish)

#

*Jumbo Frames = Good aka "more better" (I think... lol)
Must be enabled on pc ethernet properties as well as on Groovy mister core.
Set to 3800 on pc if possible. I had to do this via my registry editor. (I think it worked. It's working, so maybe?.. Just have to believe!)
You will also need to set this same amount on your RA config file for MTU speed. GM, I am not 100% sure how jumbo frames is handled or if it just accepts it without a configuration setting. I wasn't able to find a setting in the config file to specify that amount. Maybe someone else is able to clarify how jumbo frames works on Groovy mame? or if there is a specific config setting for that.

#

*Transmit buffers set as high as you can for what your network adapter allows. I changed mine in registry editor to recommended amounts (1024 incoming & 2048 outgoing), however I'm not 100% I'm getting those values as my particular adapter showed capped much lower. I haven't had an issue with it though, and realized I don't have any pci slots to expand this pc, so I'm just working with what I have. My performance is excellent though. Only minor issues/slowdowns I see are mainly in certain Flycast-Naomi 1/2 titles.

#

*Generally seems recommended to disable "power-saving" or features (on network adapter) that sound like they might throttle your speed

*Graphics renderer you choose in RA/Mame does not matter as it's pulling video RGB signals/audio prior to that process, with the exception being Flycast that the graphics renderer you choose makes a difference in performance - Source: Calamity on Discord/Groovy Arcade/NoGPU thread.

#

*I found Retroarch easier to map my controls initially, by leaving the keyboard input setting (on RA config file) to the PC keyboard, mapping all of my buttons on both controllers, then once that is all setup, I like to change my keyboard to my mister keyboard (in the RA config) since I have one of those little wireless keyboard pads. Makes it super handy for pausing your game/and/or getting into game settings, latency, etc. Also handy with mame for pausing and utilizing settings midgame.

#

*FTP & update all is a little corky I've found after setting up a dedicated ethernet connection since it will try to default to your ethernet connection first each time (making FTP inaccessible even via my Wifi connection for whatever reason, and update all tries to connect to your pc hitting a wall). I've found that disconnecting my ethernet/Groovy connection at the mister temporarily, and just utilizing my Wifi adapter on the mister, is a good workaround for this. I'd be all ears for hearing more though if there is a better way to handle this (when going PC direct to mister via ethernet w/o router).

I use this https://github.com/BossRighteous/GroovyMiSTerCommand running as a service with xvfb to launch groovymame in a headless state on my linux machine. Then you just have to make .gmc files which are launched like any other rom from the Groovy mister core to boot up mame without needing to interact with the PC at all

#

If you need more buttons for coin, start, etc., you could probably define them as analog sticks in the mister main and have groovy mister send analog controller inputs to mame

empty fulcrum
#

It really surprises me that those extra buttons aren't already linked, or easily exposed.

#

But there's so much variability in the MiSTer ecosystem that I still don't really understand how my own setup - with an Irken JAMMA Expander - functions. It's different enough that some instructions make no sense to me.

#

I've got the gmc files running. It's not a fast process if you're hand selecting the titles from a complete Mame archive, but it works very well when set up.

Gotta go do my two hour shift at the button pushing factory, will tackle the credit and start button issue when I return.

Hi, I don't own a MiSTer yet (ordered one yesterday) but I was wondering if GroovyMiSTer only works with a recent version of GrovvyMAME. The reason I am asking is because I have a arcade cab connected to an old PC (Athlon XP 3200+, Windows XP) and on this PC I am running a version of GrovvyMAME from 2011. Newer versions don't work on this PC. Thanks

Is it possible to put -flipx -flipy in the GMC files?

woeful notch
#

You should be able to put it in the exec_args

empty fulcrum
#

isn't that a global thing?

#

I don't see exec_args in the GMC, only config.json

empty fulcrum
#

I can't work it out. If I run mame from the command line, 'mame.exe <game> -flipx -flipy' works fine

#

but adding those options to the config.json I get an 'unknown error' for mame.exe [-flipx -flipy gamename]

#

@lilac grove - Can you shed any light on this?

woeful notch
#

You would make a new variable in your GMC files

# 
    "cmd": "mame",
    "vars": {
        "MACHINE_NAME": "ddpdoj",
        "FLIP": "-flipx"
    }
}
#

and add it to the exec_args

empty fulcrum
#

I did that, still got the error

empty fulcrum
#

Was really hoping someone would solve that while I was asleep!

woeful notch
#

that space in the flip variable might be messing with things

woeful notch
empty fulcrum
#

They're already rotated correctly (as in, they're filling the screen when the physical CRT is vertical) but they're 180 degrees from where I need it to be. Both flipx and flipy at the same time results in a 180 degree rotation, correcting the display.

#

rol and ror only do 90 degree rotations, as I understand them.

woeful notch
#

I think the space in your variable is the problem, so you'd probably need to split up the flipx and flipy into 2 vars

empty fulcrum
#

I'll try that.

#

Yup, that was it! Good call.

empty fulcrum
#

I'd love to make this slightly easier, make it one changed line per game instead of three. Select a different INI file maybe? Not being able to add spaces makes it a lot harder too.

woeful notch
#

yeah, seperate mame.ini would probably work. There's an -inipath argument for mame.

empty fulcrum
#

Gotta put a space in that line to make it work.

woeful notch
#

just build it into the exec_args in the main config
"exec_args": ["${MACHINE_NAME}","-inipath", "${INI}"]

empty fulcrum
#

Pretty sure I tried that in my endless iterative attempts to make this happen, but I'll give it another go to be sure

#

It's very likely that I don't understand JSON syntax well enough to have succeeded.

woeful notch
#

This is what mine looks like
"exec_args": ["${MACHINE_NAME}","-inipath", ".", "${ROTATION}"]

empty fulcrum
#

the spaces after the comma not being between quotes makes my brain hurt.

#

Yup, awesome, that's sorted it. Made a second "cmd": "mameflip" that has the flipx flipy baked in. All I need to do is select mameflip instead of mame, and it works (don't even need a new ini)

#

exec_args": ["${MACHINE_NAME}", "-flipx", "-flipy"]

That's a good way of doing it

Still need to figure out how to pipe the coin/start from the cabinet to the emulator. Got any suggestions there while you're being so incredibly helpful? 🙂

woeful notch
#

how many normal buttons are there on your arcade cabinet?

empty fulcrum
#

Anywhere between 1L 3B to 2L 12B depending (up to 2L 16B in some rare cases). Plus 1 coin and 1 or 2 start.

#

Also I really do appreciate your help up to now, thank you.

woeful notch
#

I'm not super familiar with how JAMMA adapters work, but can't you split up the 1 player and 2 player side as two separate controllers? Then in the groovy core you could define buttons 1-8 as your standard 2 rows of buttons and buttons 9 & 10 as start and coin, then set them in mame

empty fulcrum
#

My setup seems to use keyboard inputs OR controller, and I don't have controllers attached, so...

#

Most arcade cores work without being modified, it's only older cores that need me to spec the buttons before use. I don't know what that suggests, it's the only setup I've used.

empty fulcrum
#

OK, there's a setting in the mame.ini called *keyboardprovider *

#

setting that to mister instead of auto makes the normal mister controls (coin and start) work properly.

#

so now I can launch, play and re-launch games entirely from the mister.

I'm curious what people consider is the main use case for groovy. Is it arcade/mame, or other consoles too? Cabinets or consumer TVs?

limber loom

For me other consoles: RetroArch, dolphin and flycast. But of course GroovyMame supports a lot more arcade games then MiSTer itself, so that's also a big plus. I've used it with a consumer CRT

could also use mistercast to play steam games (like ufo50) on a crt

I use it to get a handful of games (lots of shmups) that aren't quite yet available on the mister ecosystem, up and going on my array of rgb modded consumer TV's, and also just loooove being able to utilize the mister and it's extra low latency features to play those games in my preferred setup. It's honestly mind blowing how low of latency it's able to maintain. I mainly use Retroarch, Mame, and Flycast with the core so far myself.

glass zealot
#

I use it to centralise my retrogaming environnment on the MiSTer. I use it both on my CRT and OLED screen

shut oriole
#

For me it's mostly to play 240p arcade games that don't have cores on a consumer crt, and online multiplayer on the crt (fightcade, retroarch netplay).
Mistercast is also great to watch old tv shows/anime on crts without struggling with the video/sound codecs compatibility issues of older devices. And play pixel art/240p modern video games.

Besides Mame, I use retroarch with groovy mister for multiplayer SNES randomizers that use the USB2SNES protocol like the Super Metroid x ALTTP multiworld randomizer

I have a realtek in my setup too, maxes out at the same. You can tweak the settings in registry editor to have higher transmit buffers, and it does show the change, however I'm not sure settings will actually go that high. However most of my content plays really good though using the jumbo frames settings in 240p/480i. I haven't really tried much or any 480p content myself yet, other than mistercast and I wasn't doing so well with my realtek adapter and that particular app. Everything else is running fantastic though.

My guess is the pc end is lagging, busy doing OS stuff for a moment then catches up. On a gigabit LAN there's just so much excess capacity that you're chasing ghosts trying to tune that part of it.

Hi all, I have just tried out GroovyMiSTer for the first time. Works really well with groovymame and the fbneo core in Retroarch. But I have 2 questions:

  1. I couldn't get my joystick (and keyboard) to be recognized in groovymame when I plug it into my MiSTer, only works when pluged into the PC. I have set "joystickprovider mister" in mame.ini.
  2. Is it possible to to play PS2 games in Retroarch using GroovyMiSTer on a CRT? PS2 games run fine in Retroarch on my PC monitor, on my CRT the screen is black but gamesound is working on my CRT.
empty fulcrum
marsh phoenix
# unique kite Hi all, I have just tried out GroovyMiSTer for the first time. Works really well...

The way I had to do it, was to temporarily set "keyboardprovider" to keyboard, that way I could navigate the mame menu with the pc keyboard, then select each input one at a time (considering you've already mapped controller inside of groovy core) and bind the mister buttons accordingly in Mame. Then once completed, I switch that setting back to Mister so I can utilize keyboard functions without having to use my PC display. (would need to switch physical keyboard obviously as well, if you don't have separate keyboards, like one plugged into each)

#

not sure on the ps2 stuff. I don't utilize RA for that

hidden moon
#

ya'll I haven't been able to figure this out online and I can't test it just yet (soon™).... does the core forward inputs from MiSTer controllers to the host PC, or do controllers need to be hooked to the PC directly? does it depend on what software you're using?

limber loom
#

Controllers are connected to the MiSTer, which makes it so convenient. I believe up to two are supported. At least groovymame is supported but perhaps simply all Groovy Mister supported emulators?

empty fulcrum
#

The question then is: how do you configure that? Because afoe a few people it isn't working OOTB.

limber loom
#

This comes from the nogpu channel in the GroovyArcade channel

#

Quite a while ago I did it myself, unfortunately dont know from memory. But you can find all info there for sure

that's so freakin' cool, thanks for the answer. I've been putting off routing a network cable to my room but it's probably about time

For some reason I was unable to get the joypad to work from mister side when I was choosing mister only for the joypad. Then I got all the input devices to be mister over the ini file and the joypads worked. later I reversed the keyboard and everything was alright. (this happened on groovy mame, I haven't trid retroarch)

limber loom
#

Another cool feat I read is that you can launch all games from MiSTer with an mgl. You can choose which emulator the game runs on and pass specific config as well. This way you'd never need a keyboard and do everything from MiSTer

empty fulcrum

But passing config options this way isn't possible as far as I can tell. If you know how this can be done please do tell me. 👍

There's some tips on that listed above in this thread if you do some searching. Short of it is basically you need to set buttons within the groovy app, then on the pc side, I found it's best to leave PC keyboard setup while binding the buttons in Retroarch or Mame, then once you've succeeded at that, you can set the keyboard back to Mister for better functionality (in my opinion), since it will allow you to pause, adjust config mid-game, etc

tulip sentinel
# empty fulcrum <@436625621662302228> - maybe this helps? I've never needed to do it.

My controller did work, it was just that games requiring analogue input would need remapping. (ie. hat left/right instead of default left/right)

Toptip: set Server settings in Groovy core as following:

  • PS2: Keyboard & Mouse
  • Joysticks: Analog

And set all 4 providers in mame.ini to mister.

And.. if you want to play operation wolf; also set lightgun etc and other relevant inputs to mouse in mame.ini

Hi! I’m looking into seeing if Groovy MiSTer is something I could use, but running into issues where documentation and guides seem to think I know more than I do.

#

Do I need to connect the MiSTer directly to my pc using a LAN cable, or are the MiSTer and PC supposed to be physically connected to the same internet connection?

tulip sentinel
#

the latter is fine. the less latency the better of course.

sacred ermine
#

Thanks, I got it working but my latency is very poor. I have no way of hooking up either the mister w/crt or the pc to the internet except wirelessly. Different room in the house and only one port in the whole house.

#

Connecting the pc to mister with a chord would be easy but I guess wouldn’t work for groovy then.

empty fulcrum
#

You CAN run over WiFi but it's right on the edge, every time there's any hiccup at all you'll de-sync the two systems and it will be bad.

#

And that's with a fast WiFi setup. If you want it to work well then you must hook them up with a cable.

#

A 5 port switch for your LAN is dirt cheap, so if you're able to run cables, you don't need to worry about only having one remaining port.

sacred ermine
#

I am not able to run cables, is the problem.

It doesn't really handle packet loss, which WiFi has in droves.

Also, I still had losses with the direct cable connection which helped me realise the importance of;

  • Changing settings on the PC end that ultimately improved the performance more than anything
