thx @olive ferry

grand moss
#

That's right - there are several games which won't run on the American System 3.0 BIOS, so I tell people to use the Japanese one in order to prevent problems

#

Alshark, Bonanza Brothers, and a few others

#

For CD-GAME, can I only change \Cheats\TGFX16-CD*.zip to the same name as the game and put it into games\TGFX16-CD\ for use? It seems that HU-GAME with *.pce does not need to do this...

grand moss
#

I don't know how cheats would work on TG CD, I've never looked into the cheats code

#

Maybe somebody else around here knows

shut walrus
#

That is how it works yes

#

I dont have any great insight into changing it mind you

coarse shadow
#

Cheats for PC-Engine CD games seems complicated enough. A lot of the Gamehacking.org converted cheats for MiSTer won't work properly. I mostly use cheats patched directly into the CD Image, via hexeditor.

#

MiSTer cheats for HuCard games are mostly fine though.

#

You supposedly need a bios that is byte swapped.

#

I would have assumed that if this is true, having one that isn't would just fail completely, but that apparently is not true and I don't understand it.

shut walrus
#

I wouldnt know where to find something like that, but Id like to try it out

true flare
shut walrus
#

So 3.01 is byte swapped?

true flare
#

There's no 3.01.

shut walrus
#

It isnt clear to me what the updater is currently downloading, if that is a byte swapped BIOS, etc

grand moss
#

If you're not using the Japanese BIOS, you're probably using the wrong one. That's not byte-swapped.

#

Japanese 3.0 is most universal

true flare
#

Is the byte swapped thing true? If it is, why would having it byte swapped work at all?

grand moss
#

The only thing that could be byte-swapped is that the American cards were reverse-order from Japanese, but that's a toggle on MiSTer, not something that you need to do. And the American System 3.0 Card has too many incompatibilites (because the Japanese games check for specific memory locations), so just use the Japanese card, and forget about byte-swapping

#

Most American ROMs out in the wild have already been byte-swapped anyway, so again you don't need to worry about it

true flare
#

So that thread is nonsense then?

grand moss
#

I have no idea where the byte-swapped thing came from

#

but then again, I don't use the cheat engine, so I don't know the specifics

true flare
#

According to the thread,the mister core readme mentions the byte swapping.

https://github.com/MiSTer-devel/TurboGrafx16_MiSTer

CD-ROM images must be in BIN/CUE or CHD format, and must be located in the TGFX16-CD folder. Each CD-ROM image must have its own folder. cd_bios.rom must be placed in the same TGFX16-CD folder as the images mentioned above. Japanese Super CD-ROM v3.00 is recomended for maximum compatibility. Additionally you can use a different bios for specific games (for example from Games Express) by placing cd_bios.rom inside the game image's folder.

Do not zip CD-ROM images! It won't work correctly.

Attention about US BIOS: MiSTer requires original dump of US BIOS to work properly. It needs to be of 262144 bytes. If you can read copyright string at the end of US BIOS file, then it's not correct dump! It's already pre-swapped for emulators. While it will work on MiSTer, some CD games will refuse to start. Correct US BIOS file is when copyright string is not readable.

#

this seems to be the only place where any talk of byteswapped bios is written

grand moss
#

Japanese Super CD-ROM v3.00 is recomended for maximum compatibility.

#

In the first paragraph

astral valley
#

yeah I just think maybe some people are getting confused because the US BIOS talk right after

true flare
#

My confusion is to how a byte swapped bios could work but cause some games not to start. You'd think it would cause all games not to start.

grand moss
#

The reason some games don't start is because they aren't compatible with the US BIOS. (Games' fault)

#

several different reasons for this, but anyway, that's why we say use the Japanese bios

true flare
#

But the way that is written it sounds like they fail to start because it is byteswapped.

#

Also I saw a place which claimed Future Boy Conan doesn't work with a US bios. I had it and it absolutely does.

#

Unless there's just some obscure crash I didn't notice.

grand moss
#

Alshark, A.III, Bonanza Brothers, and some others.

true flare
#

I didn't have any of those.

grand moss
#

In any case, on MiSTer, backup RAM is created separately for each game, so there is no need to go into the backup memory manager, which I think is the only place I've seen Japanese text on the Japanese BIOS (which means there is no reason for users to avoid it). I hav to remind people to use that BIOS every so often because somebody comes to report that some game isn't working with the US system card (as would also be the case on real hardware)

olive ferry
grand moss
#

I don't understand what you are trying to accomplish, or what issue you are talking about....

#

If we are talking about the System BIOS for PC Engine (or US TurboGrafx), there is no difference in the available fonts. Not sure why additional fonts would be helpful ?

zealous dock
#

I'm totally lost here hehehe

#

I think you just need rename the cd-rom bios

#

That works for me

#

Relative newbie to the PC Engine library, curious to ask those more familiar how critical you find turbo for PCE games?
Struggled to find old chat around the autofire rate of MiSTer being different, but wondering how critical this is? I've been looking at getting dshadoff's SNAC design to avoid issues, but don't know the library well enough to know how sensitive this turbo fire timing is

#

Was reminded of the topic in mylifeingamings recent video example with Legendary Axe, perfectly timed to keep a boulder back in that game.

regal valley
#

its more of an issue if you are used to it to play some ganes

grand moss
#

If you use USB controllers, I added an option to use additional buttons for the "correct turbo". One choice in the Hardware menu is Controller, which until recently was "2-button" / "6-Button". Now it includes 2-button turbo.
If you look at a SNES controller for reference, the buttons labelled A and B are "turbo low" if you press X and Y respectively; and "turbo high" if you use L and R.
You'll need to figure out whatever actual buttons those map to on your own controller (and setup); I'm using those as a basis for communication, since the SNES buttons are the ones used for reference during the controller setup on MiSTer.

shut walrus
mellow crane
#

That's funny

hoary quail
grand moss
#

You can... I just use a SNES-type controller, and they're already defined. I don't spend any time remapping keys though.
The only thing I do is go into the Hardware menu and choose Controller: 2 Turbo

#

(It's not the default)

hoary quail
#

Maybe my mapping has overriden the turbo then.... I'll try and delete the config file

#

I am getting turbo, but I seem to get Button II Turbo at the same level using both SNES Y and R. Seem's like a "turbo low"

grand moss
#

Some games they are hard to tell apart

hoary quail
#

I think that was indeed my mistake. It is definitely doing something! False alarm. Thanks very much for this feature. Noticed it isn't listed as a feature anywhere in the GitHub main page for the core, or the help from what I could see. Really nice to have though

grand moss
#

Ah OK, I'll see if I can update the readme on the github repository tonight or tomorrow

olive ferry
grand moss
#

That's basically a Japanese 3.0 BIOS anyway

#

When somebody wants to write a translation patch, they need to rewrite the print function.

olive ferry
grand moss
#

Part of that work requires a new font. Usually the game already uses a lot of memory, so it's hard to fit into the game. Putting it in the BIOS reduces that requirement on "game memory"

grand moss
#

French/Spanish/Italian... that's probably possible

#

Arabic, Urdu, Chinese - not really possible.

olive ferry
grand moss
#

The Japanese BIOS already contains a few thousand Japanese kanji, which have some overlap to Chinese hanyu, but it's not sufficient for Chinese sentences.

olive ferry
olive ferry
#

The recently launched analogue duo cannot use customized bios. Maybe it also affects the translation game?

grand moss
#

About Analogue, translated games shouldn't be affected, although they may not be recognized if Analog has a "database".
There is only one game which requires my English font BIOS, and that should be OK if the BIOS is run from a multi-cart like the Everdrive

olive ferry
grand moss
#

How recent is this ? And is there a link ?

olive ferry
grand moss
#

It sounds intersting

#

Let me know if you can find a link to learn more

#

I would expect that it would use only a limited vocabulary - probably less than 2000 kanji were in the ROM in the first place, and they could all be replaced, but that probably wouldn't be enough for proper Chinese... maybe it's for smaller-vocabulary usage ?

#

Also, I assume this is simplified Chinese, not traditional ?

olive ferry
#

If there were suitable fonts, would it be possible to add more languages?

grand moss
#

I guess... but there would still need to be changes to print functions, and translated texts.

#

Translations take a lot of effort (and the hacking does too).

#

although if somebody is taking an English translation and re-translating it to another language, there may be less hacking work needed (because there is already a template)

When I was a kid, I used to play "Motor Roader" with my friends for 5 people. It was a nostalgic time.

Imagine all the games that you ever saw were NES-level, then seeing some HuCard games and being reasonably impressed....

#

then put in Ys Book 1 & 2 through a stereo

#

or Super Darius

#

Totally different than cartridge games

olive ferry
#

Yes, so I have always thought that pcengine is a highly collectible console and game, with rich and interesting 2D GAME treasures

#

I will never forget the day when I put the amplifier on YS Street, and Tengai Makyo - Ziria, Ryuichi Sakamoto's music was amazing

shut walrus
grand moss
#

Agreed. I don't think it would have the same impact today, but back then it was amazing (the CD music)

shut walrus
#

I find that particular era/media/platform of CD games really interesting and aesthetically pleasing. Its not FMV, its not digitized actors, its actual sprites and background layers imitating these things or anime cells with voice acting

#

So cool

olive ferry
#

Designers need to make amazing designs in extremely small bits, and I think many of today's high-resolution retro games don't really grasp these innovations.

#

Ys Book I&II is still the only legit TurboCD game I own

#

I love it so much

It was amazing to experience back then

solar fjord

Ys is like an RPG game, right?

Action RPG, yeah. Like Zelda but with bump n grind combat

solar fjord

So kinda like Hydlide then

mellow crane
#

Yeah. Fair comparison. But better imo.

Yeah, saw an AVGN review of Hydlide, I myself tried to play that, and yep, horrible

I never enjoyed it myself. Ys I and II have amazing music so that's a plus

Hahaha I forgot about that

plucky python
#

Some of my all time favorite gaming memories are of getting the TG-16 and Turbo CD with Ys. One of my friends got it first and I was absolutely blown away by the music and anime cut scenes. I worked all summer to save up and bought it for myself Christmas of 1990 if I remember correctly. It became the show off toy anytime neighborhood kids came over or my family had company at the house. Good times. And yes, I had it hooked up to my stereo system. I still listen to the Ys soundtrack to this day.

#

This chat reads like a Ys commercial, now I want to play Ys.

astral valley
#

yes you should play it

languid pagoda
#

Dunno what you're talking about.

#

regal valley
#

the PC Engine soundtrack for Ys is really something else - even the intro is a banger

Feena、Reah and Lilia...

hoary quail
#

MiSTer is like the perfect Ys 1-5 machine. Never played the series until I tried the SMS Ys 1 a year or two ago. Now one of my all time favourite series

#

PC Engine versions are fantastic, as someone with zero nostalgia I also listen to soundtracks on repeat

languid pagoda
#

So for someone like me who never played Ys, which versions would be the ones to go for on mister?

astral valley
#

Ys Book I&II on turbocd

#

all the Turbo/PCE CD ones are great and then there's an alternate 4 on SNES and then 5 also on SNES

languid pagoda
#

4 and 5 are Japan only, right? So I'll have to grab a fan translation for that.

hoary quail
#

Think so. The 4 translation really is impressive. No idea how such things are done, but VO and all

languid pagoda
#

Studying wikipedia I found out there are 2 different Ys 4 🤯

#

Is one considered to be the "true" ys4?

mellow crane
#

The PCE one

#

Actually, the most recent remake is canon

#

Memories of Celceta

#

Which is essentially a remake of 4 on the PCE

hoary quail
#

If you do enjoy the old ones, playing chronologically is fun due to these sorts of changes. Generally I think any remake becomes new "canon" but seeing the really obvious nods and changes since old versions like PCE is great. They do seem to care about the little details

languid pagoda
#

I never played an ys, but I enjoy the orginal versions of ff more than the pixel remasters and in general have a thing for old versions. So I'd start with the pce versions I guess. Remakes can be fun, but never replace originals imo.

mellow crane
#

Ys 8 is great if you want to play a modern one.

#

Just avoid Switch version if you can. Performance sucks

languid pagoda
#

Thanks for the heads up. It's always a shame when the switch version sucks, I like the flexibility of the system.

Hi, i have some doubts about modeline core

#

It's correct 270x231 with 60.1hz?

#

I believed pcengine runs on 256 with 59.82hz

#

I see on rtype, another vce clock at 59.82hz for 3xx modeline. Just thinking if vce flexible clock it's implemented

Anyone agree that the Raw RGB setting makes the TG16/PCE look so good?

#

🙂

#

Just finished fully assembling my MiSTer, and the Raw RGB looks better than Original on TG16 core

#

Try Bonks adventure as an example. It is so saturated his skin looks reddish using raw RGB. There is a reason why original is the default. It is the most accurate compared to the original console. Definitely try it with more games.

grand moss
#

It's very much a 1988/89 game mechanic, but the graphics and story are a step up from that

#

Not a huge step up though

#

But the translation itself is good

#

and the English text looks a lot better than the original Japanese, due to the way the translation changed the print function to variable-width font

Nice!

Such an exciting release. I'm hopeful we'll see more PCE RPGs translated.

I just got a Reflex adapter + PC Engine controller adapter. What are some recommendations for PC Engine game pads (not joysticks)?

upbeat lintel
#

For the most part, the standard 2 button pads are all the same with only cosmetic differences. Some early white ones don't have turbo switches, but turbo doesn't work with Adapt.

crisp elk
#

I'm considering a 3 button pad since the 3rd button can be an action button in some games

regal valley
#

the turbo switches are part of the experience. some games use them better than others

#

the Avenue Pad 3 is a solid choice, you can customize what the 3rd button does (even turn it off)

crisp elk

Yea I may just get an Avenue Pad 3

Hori Fighting Commander is my favorite 6/2 button control. Feels like a SNES.

crisp elk
#

@upbeat lintel yea I considered the Hori Fighting Commander but the Reflex adapter doesn't support 6-button games (but it does support 3-button games). It is really expensive though and I prefer an OEM PC Engine controller I have a different controller for NES, SNES, Genesis, N64, Saturn and PSX along with a Reflex adapter for each

stiff lotus

#

@stiff lotus oh OK now if it also supports 3-button and 6-button games then I am in for one of those

stiff lotus
#

I think so! Says it works with all known original controller hardware.

restive wren
#

It’s turbo that requires the special PCE SNAC for 100% accuracy. Everything else is close but not perfect. The games themselves need direct communication with the controllers which isn’t possible over USB.

crisp elk
#

@restive wren thank you for explaining. I may just get the SNAC adapter for Turbo then since it plugs right into the user port

While we're on this subject, I have an original TG-16 2-button pad, just picked up a Hori Fighting Commander 6-button pad, have Porkchops Reflex Adapt and dshadoff's PCE Snac adapter. My question, having never owned or used one, is there any reason to pick up the Avenue Pad 3-button controller? I assume the Hori will work with any 3-button compatible game, correct?

crisp elk
#

@dapper bobcat that's a good question since I considered the Reflex adapter and the SNAC. Since the SNAC adapter supports turbo, I would get the SNAC adapter + Avenue 3 pad since I don't care for SF2 on PC Engine. Now I am wondering if I get a Hori Fighting Commander, can I assing 3 of it's buttons to button I/II/II, and then the other buttons to turbo I/II/III since the turbo switches don't work with the Reflex adapter?

hoary quail
#

There's a controller mode that helps with turbo specifically (thanks dshadoff for adding a little note to the GitHub after my confusion some days ago);
"For 2-button 'turbo' joypad (sync'd as in original system), turbo fire is provided by alternate buttons : A, B (normal), X, Y (turbo 1 level), and L, R (turbo 2 level)"

#

So for the controllers with I/II/III, what you proposed would be possible, but only for I/II buttons it seems. Would you want it on III too?

grand moss
# dapper bobcat While we're on this subject, I have an original TG-16 2-button pad, just picked ...

The 3-button pad doesn't add an input; it only makes the 'run' or 'select' more convenient for games that use RUN or Select in that way (i.e. Valis III, Forgotten Worlds, etc.). I never actually used a 3-button controller, and my life does not feel incomplete.
The Hori Fighting Commander 6-button for PC Engine is a really good 2 and 6 button controller. But it doesn't relocate RUN/Select to any of the regular buttons

grand moss
crisp elk
#

@grand moss OK good to know. Since I can't assign alternate buttons on this core to a 6-button pad, I will get a SNAC + Avenue 3 pad

stiff lotus
#

Do any PC Engine games benefit from a 6 button controller? I guess besides street fighter.

grand moss
#

SF2 is the only HuCard. But the following CD games support 6-button in some way:

Princess Maker 2
Ys IV
Advanced Variable Geo
Battlefield '94 in Tokyo Dome
Emerald Dragon
Fire Pro Jyoshi - Dome Choujyo Taisen
Flash Hiders
Garou Densetsu II - Aratanaru Tatakai

Ryuuko no Ken
Sotsugyou II - Neo Generation
Super Real Mahjong P II - P III Custom
Super Real Mahjong P V Custom
Tengai Makyo - Kabuki Itouryodan

None of them require 6-button

I got about 90% through Ys IV in 2 button mode before I learned it supported 6 button.

3 button controller

#

I have a few,I like it

#

it maps the 3rd button to Select or Run, and some games make use of that

#

I just got an extension cord to try it with my Duo (works fine on MiSTer with SNAC or Bliss)

weak ivy
#

Yeah that's nice. So you don't have to press start/run in the awkward middle of the controller.

true iris
#

The avenue 3 pad is huge and awkward, the dpad is stiff and feels like it has too many sharp edges. Not enough games make it worthwhile either. I never liked it. The hori 6 is sublime. Basically the perfect 2D pad.

#

The 6 button sold with the duo RX (same as the PCFX) is also a great pad, but it takes a bit of getting used to.

Does anyone know if the 5 player multitap is planned to be supported with snac? I have the USB style snac adapter which after filling about with different cable lengths works lovely but would love to have the multitap in there aswell

regal valley
#

its serial so it should work?

grand moss
#

SNAC, by definition, already has support for peripherals like this, because it is logically equivalent to the original port.
However, electrically, the signal transition time on the 'normal' SNAC circuitry is not fast enough for a lot of uses. I had designed a different circuit to support PC Engine/TurboGrafx signalling, but it is specific to that core and is not to be used with other cores.

@grand moss Quick question for you. I am using the 240p test suite 1.12 for Super CD-ROM^2 with mister.ini set to direct_video=1 for the RetroTink4K external scaler. I am using the test build for mister and the PC Engine core with DV1 support. I am on the latest RT4K firmware. I noticed that the grid tests show an extra line or two of black/blank at the bottom. Also, the 512x240 grid is not centered. Is this by design? (as-in native to the way the console outputs)

#

Also, can you explain the MiSTer OSD showing two resolutions? I thought one was for what the console core is outputting (the top resolution) and the other was for what is being packaged for HDMI (the bottom resolution). If that is the case, then the bottom resolution is possibly cutting off 2 lines (242 vs 240)?

grand moss
#

I don't have the RetroTink4K scaler, and don't know what this "DV1 support" is that you're talking about. I am not clear whether the latest RetroTink4K firmware includes the fixes discussed in here ( https://github.com/MiSTer-devel/Main_MiSTer/issues/808 ) - it sounded like those would be coming out in a week or two.
I also don't know whether you are using the special-build of the TG16 core that Sorgelig made for the purposes of that discussion (it is not the public release version).

Having said all this, assuming that you have "Overscan" set to "Visible", the console should be outputting the correct number of lines, with the correct alignment if you are driving VGA. This much has been previously tested - but I'm always listening for regressions. If you are able to validate this against an original console and show that it isn't, there might be something to investigate.

The HDMI direct output is generated by the framework, and if there is a discrepancy between the VGA output and HDMI Direct, that is something that Sorgelig or some other developer might be able to help out with.... but it could just as easily be the Tink4K or the profile you are using on it.

#

When you say "DV1 support", are you somehow abbreviating "direct_video=1", and talking about what was discussed in that long issue thread ?

plucky python

My apologies for not being clear. DV1 is what the Retrotink dev calls direct_video=1 support. I am using the special mister build and the special PC Engine core build that support DV1. I only use HDMI and unfortunately I do not have original hardware. All the grids looks correct except for the 512x240 which is not centered. Just wasn’t sure of this was by design. I will see if someone on the Retrotink Discord can test as well. 😊

grand moss
#

I haven't played - on original hardware - with a version of 240 that does a 512 grid.... let me see if I can try that out on TurboEverdrive

grand moss
#

OK, on an original console, the 512 grid is centered, roughly the same as the 256 grid is.
There is however, some additional vieable area possible, depending on how the video display controller registers are set. I think I've seen it go as high as 540 or so.
MiSTer's HDMI output is also centered (if it goes through the scaler)

#

Also, I just tried the Y/C core going to my composite CRT.... the 256- and 512-wide grids are centered (same as generated by regular machine)

#

The 320 might be shifted a bit left on MiSTer though...

#

(a few pix)

#

So, I would say at this point that it's the Tink4K profile for 512 on MiSTer PC Engine core

#

I would actually question whether the profile for 512pix on regular console has actually been tuned (not that many games actually use 512)

plucky python
#

Thank you!!! I will make a post on the RT4K Discord in a bit. Do you know of an example game that uses that resolution? I would be curious if the game was not centered.

grand moss
#

I can't think of one at the moment.

#

But making sure that the capability works shouldn't be dependent on that. The number of games which have 512 pix is really more of a measure of priority/impact.

olive ferry
#

I did a test today, connected HDMI to "hdmi to vga adapter" (video_mode=rgb), and then output vga to the led monitor. After entering the game core, the picture is not in the center.
Instead, use (direct_video=1), and the picture Still not in the center, is it related to (vscale_mode), or does it require other settings?

grand moss
#

It is possible that the right edge of display may stop early - although this area would be well beyond the bezel of a regular CRT of that era. I recall seeing somewhere around 544 pixels as "possible to generate", but this is more than "possible to see on CRT".
This resolution is not commonly used on PC Engine, and the key point about whether it is "centered" would be for situations where split-resolution games have one resolution on the top of the screen and this resolution on the bottom of the screen - and ensure that they align properly. I can't think of any games that do this at the moment, but if you find one and those areas don't align properly, please let me know.

#

Yikes. That's no good.

grand moss
#

Over here, I did a couple of tests to check alignment between resolution modes on real hardware versus MiSTer

#

I ran this on original hardware, MiSTer through HDMI, and MiSTer using Y/C composite output

#

I used the vertical lines to check relative alignment between resolution modes, and found:

  1. there is no difference in alignment between MiSTer composite and MiSTer Y/C
  2. MiSTer Y/C vertical lines appear a bit different from original hardware, and appear diffuse when taking photos
  3. There are minor - and not material - differences in alignment between original heard and MiSTer, when judging vertical bar alignment on these different resolutions
#

First, here is the MiSTer, composite versus HDMI:

#

Completely different monitors. For comparison, check the vertical bars right at the left edge of the text

#

Since the composite is so hard to see (and I had to adjust brightness and contrast in order to get it even this clear), I will compare original hardware against MiSTer HDMI.... now that we can see that MiSTer HDMI and MiSTer Y/C have the same alignment

#

In these two photos, I've put a red line around alignment of a particular line, and how one resolution mode matches with the next

#

You can see that the interface between 512pix and 352 pix is exact on composite, but appears roughly 2 pix offset on MiSTer. I'll have to look into this one day. But I'm certainly not concerned about a discrepancy of this size

#

The interface between 352 and 256 seems even smaller - perhaps 1 pix

#

It might be that an oscilloscope trace may need to be taken, to accurately measure time from HSYNC pulse to start of data on both MiSTer and orig hardware for comparison.

regal valley
#

@grand moss which dev toolchain would you recommend for dabbling in PCE dev?

#

I see many versions of HuC, etc

grand moss
#

If you're comfortable in assembler, I recommend that over C

regal valley
#

I can certainly try

grand moss
#

Depends what you want to build anyway

#

I created a github organization a short time ago, and talked with several of the key people making tools and publishing information, and asked them to move everything to the organization (as I was also doing), here:

#

It's meant to a be a one-stop shop, but it's also intended to be fault-tolerant, in case something should happen to any of us, as did last year to Bt Garner.

#

So, no single-point-of-failure

#

If you're just starting out, use HuC from there... PCEAS (the assembler) is included

#

'elmer' has been adding a ton of examples as well

regal valley
#

thanks - yes this certainly helps

#

I don't have a specific goal - maybe write a litte game for fun; but I don't know what I can pull off yet if I do it in assembly

#

done some 80x86 asm years ago; nothing fancy other than some basic graphics routines for DOS mode 13h

plucky python
#

Thanks @grand moss !! I really appreciate you taking the time to research this. I know it might seem like a silly thing to fixate on by most. I just find it odd that all the grid tests look normal to me except for the 512 mode. I have noticed the Mega Drive has a similar issue (not as noticeable) in its 320 mode. Latest RT4K firmware still shows the same behavior and that camp thinks it’s a core issue. I will post my screenshot again. Just to reiterate, I am using HDMI (no analog in my chain and nothing abnormal like switchers or AV receivers in the path).

plucky python
#

This is OLED…forgot to mention.

stiff lotus
#

I know, I just want to see people think it’s actually a CRT and you somehow stumbled onto the holy grail of picture geometry lol

plucky python
#

😁

grand moss
#

So, my thinking is this - although it would need to be borne out by timing analysis (which I won't do immediately):

#
  • HSYNC pulse causes the scanline to retrace
  • this is a non-zero amount of time
  • The Video controller has a "HDS" parameter to allow for this and for stabilization and left overscan
  • The Video controller then starts sending data, to the amount of the "HDW" register.
#

First, I don't know who (if anybody) is modelling the retrace time accurately. If HDS is set so low that it doesn't fully accommodate this timing, then the initial portion of HDW output will not even be on the scanline (as it would be part of the retrace and stabilization period)

#

Secondly, The initial portion of HDW could well be off-screen, for which some sort of "bezel crop" should be instated on the CRT emulator

#

Thirdly, because the transmission of scanline output does continue past the right bezel of most CRTs' capability, this cropping should also be instated....

#

Fourthly, the core may or may not be showing the full scanline output - the right edge might need to be extended, although that portion wouldn't be visible, just as the left portion isn't

#

And Finally, 240P suite took some numbers that appear appropriate on the CRT. You would probably feel better if HDS was one or two squares longer, and the width was shorter.. but that's not how the author wrote it

#

So in summary, I don't consider this a "bug" per se, but I do consider this something of a curiosity that I would like to investigate, though the amount of time required for the investigation versus the value of the data retrieved is pretty low. There are several higher-priority investigations to do first (especially related to CDROM/SCSI controller)

plucky python
#

Agreed …this is low priority, yet interesting. Thank you again and happy to test what I can. I will be the first to admit I am no where near educated on this stuff like most of you all are, but I enjoy learning as much as I can.

Why did NEC use "HE SYSTEM" (Hudson Entertainment System?) and "HuCARD" (Hudson Card?) branding on the PC Engine? Pretty sure this branding was used on some of the TurboGrafx-16 hardware as well. Just always seemed weird/confusing to me from a marketing perspective. I think Hudson Entertainment was the original designer of the system right?

grand moss
#

Yes, Hudson created the hardware and shopped it out to NEC, who built it and sold it. History tells us that they would have flubbed it without Hudson

plucky python
#

So was it technically known as the NEC PC Engine Hudson Entertainment System?

#

Oh wait..I think I understand now. It is the Hudson Entertainment System, but as you said, NEC built it for Hudson and called it the "PC Engine" in Japan and the "TurboGrafx" elsewhere.

#

I am assuming Hudson designed the successors which NEC built and named as "SuperGrafx" and "PC-FX" as well? I wonder what the internal names were from Hudson? Super HES? 😄

grand moss
#

I'm not sure how much input Hudson had into the PC-FX. It apparently had a different CPU when the project started, and it was changed to a NEC CPU at some point. There could have been some strain on the relationship

#

But actually, aside from the SuperGrafx, all the other PC Engine machiens were just respins of the original PC Engine and CDROM

#

Even the SuperGrafx was the same chips, but one more video processor

grand moss
#

And the PC Engine was likely known as the "Hudson Entertainment System" before they pertnered in with NEC, and insisted that various components have HES on them and others HuCard.

Never seen nevermind held any other PCE stuff IRL, so limited opinion.
Feels nice to hold for me, not got the largest hands.
Find myself slightly holding Dpad side not rigidly in like a claw grip as if it had shoulder buttons to hit. I go off a little, and the sloping edges around the bottom make that more comfy than if I tried to do similar with say an NES controller.
Dpad is what it is I imagine. Seems a good condition I think. Not necessarily stiff. Eh, kinda mushy even at times? Less easy to go left -> down -> left and such compared to the M30 I have. Probably just takes getting used to. Still felt fine. Only played so far Bonk, Legendary Axe and Ys. Only even thought about the Dpad at first roaming in Ys, then I sort of forgot about it

And apparently the PCE core can’t display them properly. Has anyone heard of this?

Or perhaps it only works in analog mode, or requires some mode one setting to switch resolutions properly.

But resolution change stuff was more frequent during the 32-bit era (ie. Chrono Cross, noctourne of the midnight, etc.)

Yeah, so I said something above about this - "But anyway, if you insert cards in a specifc wrong way on original equipment, there is a weird video mode that shows 4 mini-screens in the corners, but they're all the same and unreadable"

#

what is happening here is that the video processor is being hit with some out-of-spec values that make it misbehave in a particular way

It's not a resolution thing; it's a mismatch between resolution, virtual mapsize, and screen aperture.

why would they include this as a password? Just for fun?

They programmed some mistake in the VDC registers, and the 4-screen thing happened and then they thought it looked cool. But unplayable. So they hid it

Incidentally, about a dozen of those passwords were never found until 2021

They were stuck in the game, then never advertised, and then forgotten.

I can’t speak for anyone else but I don’t care if the core supports it. Seems like a useless “feature” lol.

grand moss
#

Yeah, sometimes people search for differences. There are other more important (yet still meaningless to game-playing) fixes to make in the video display controller

#

Like this affects appearance in the case that the invalid values are sent to the video registers, but it wouldn't affect how the game acts. I know a couple of things where timing is off by a few cycles, and could affect how a game acts, although no known games fall into that category.

I suppose that the FPGA is not a perfect recreation of the internals of the 6270. But oh well. Best we've got. Maybe one day sombody will be able to map out the standard cells from the decapped 6270 and then we'll be sure.

In any case, haters are the least persuasive people.

regal valley
#

how is that different in FPGA? is it not working there?

grand moss
#

6260 controls HYNC and VSYNC; 6270 produces the background based on video register values. In this, it seems that they've made the visual aperture of X small enough that it 'wraps' twice, and same for Y. As I recall, TG16 core does this on the Y axis, but I don't think so on the X axis. These are undocumented values, and playing with these registers outside of normal ranges generally makes a TV have a twisted screen that collapses due to loss of sync.

the dump is labeled as Super-CD Demo2 - but it seems odd it would have that branding if it's direct from Hudson

grand moss
#

Well, I don't know what to say. Some of the in-store demo discs were abbreviated games (playable demo), and some were the actual game, but with different printing on the disc. Either way, they seem to be popping up with high prices, and don't have any "new" content - just possibly a different revision of existing content.

true. not worth getting it at the asking price

#

For y/c composite, do you still set colors: original for more authentic look?

grand moss
#

I don't recall what the choices are named, but I use the one that's not strict RGB (which is probably original)

jovial jackal
#

Ok cool thanks. Original is what I use. I should actually dig out my duo and compare

grand moss
#

Yeah, give it a check. Anybody who has real hardware has noticed that some games don't look right in the RGB of emulators. But anybody who has only played emulators doesn't know what the original games looked like

#

That's why, back in 2020, we set out to correct the palette

#

Multiple layers of how it's different, but I won't go into that.

slim yew
#

Worse than just rgb of emulators though. One of the reasons mister doing that work is so great- the mister output is more true to intention than the output I use on my coregrafx

grand moss
#

Not sure I understand what you are trying to convey

#

On your CoreGrafx, are you using composite output, or did you get a RGB mod ?

slim yew
#

I use rgb output, so I do not get the intended colors.

#

Therefore, the work done to map the composite colors gives me a better and more developer intended experience than on my actual console

grand moss
#

Gotcha

regal valley
#

its hard for me to unsee the warmer composite palette, so now I play my real PC Engine on composite😅

olive ferry
#

It should only have an RGB color palette, but it is actually displayed as RGB to YUV. I know many admirable brothers have studied this conversion rule and established another accurate output color palette based on this rule.

grand moss
#

Yeah, it's internally tracked as though it's RGB, but at the very least, those values cannot be considered to be on a linear scale (which all emulators do). Internal to the HuC6260, there is a lookup table which has a similar but different decode to YUV which makes the range more viewable (no colors crushed at either bright or dark end), but also uses a more linear luminance scale.

#

But the composite palette we created also tries to simulate the slight skew introduced by the analog output stage which mixes and amplifies the signal

regal valley
#

that palette, plus boosting the chroma on my CRT makes for some really nice result

only RF from the TG16 is good enough for me!

I love that those have been extracted for solo play 👏

#

@covert sinew Presuming you’re the one with the same YT name, nice videos 👍

grand moss
# covert sinew Anyone working on those?

Xanadu has been a project for many years; the translator wanted to also do a dub because of the amount of spoken language in the cut-scenes, and how important they are to the story. That part of the project has taken a long time.

#

Seiya Monogatari has been extracted and is looking for a translator (must be experienced because the script is not raw text, but includes a lot of special codes which must remain intact - trigger effects during speech, etc.)

#

Tenshi no Uta - I think these are also extracted, but at least partially understood.

#

Translators are usually the missing part

left merlin
#

In my own experience, it’s not just missing translators, but people who are willing to do it and keep at it, that and the person who is coordinating the entire transaction between various people on the project. That’s not a joy to deal with

grand moss
#

Well, in these cases, the hackers are doing the interstitial parts

#

When you say, " it’s not just missing translators, but people who are willing to do it and keep at it" - of course, that's expected of the translator - to complete the work. Otherwise they're not performing the role.

#

The hackers in the above cases have been around in that scene for years, and built tools to get to the point of being able to extract. And of course testing is required of every team member. But I can't imagine a person who translates a thing without actually actually play-testing it to re-evaluate context (or that their work doesn't just crash)

you're talking about the daughterboard with the scratchpad RAM and the HuCard socket, inside of PC Engine (white) and CoreGrafx machines ?

Is it true that S-video is the most accurate colour representation for PC-Engine?
can a SCART with Sync-on-Luma do the job that S-Video can do?

olive ferry
night breach
#

Yep I installed the turbonanza 🙂 just wondering if these SCART cables with Sync on Luma is the same as an S-Video cable. Or maybe there is a palette on the PCE core

olive ferry
grand moss
#

Summary:

  1. PC Engine's composite output is already excellent to start with, for two reasons: a) all possible pixel clocks are aligned to NTSC frequencies, either as direct harmonics or half-harmonics, b) the B-Y and R-Y outputs from the color generator chip are already modulated within the chip, so the signal is clean

  2. S-Video modification should be as good as it gets because the R-Y and B-Y signals are already modulated; the S-Video mod simply amplifies them separately from luma (on the original console, they are all mixed together). The color outputs are derived from an internal lookup table in the chip, so there is a difference between S-Video/composite colorspace and RGB.

  3. On MiSTer, a lookup table was implemented to simulate the composite/S-Video colorspace as closely as possible.

I don't know anything about the SCART cable you are referring to, though

olive ferry
random bloom
#

The Retrotink 4K will take any of those SCART variants, but that's a pretty big hammer. Run the svideo from the Turbonanza into it and it's very close to RGB quality but with the composite palette.

jovial jackal
#

On my setup, composite via analogue io vga -> active y/c adapter, original palette mode on mister is still more saturated than my duo. But I don't know if my duo is optimal. I had it recapped by someone few years ago and they did a pretty shoddy work...

grand moss
#

Probably the active y/c adapter

jovial jackal
#

Yeah that's my guess

grand moss
#

have you tried MikeS's modulated composite ?

jovial jackal
#

Hmm... don't know what is

grand moss
#

well, I should probably ask - when you say "active y/c adapter", where did you get it from ?

jovial jackal
#

Oh, misteraddons

grand moss
#

Oh, OK, then you are using MikeS's composite

jovial jackal
#

Using y/c adapter via direct video adds even more saturation

#

It's all fine at the end of the day. I'm very happy with y/ ccomposite

#

y/c

#

Definitely prefer original palette

grand moss
#

Yeah, I think it might be slightly more saturated.... but that might also be because the normal DAC is 6-bit

jovial jackal
#

Was there official svideo out for pce?

grand moss
#

No

jovial jackal
#

Ah so just rf and composite

grand moss
#

There also wasn't an official RGB out

#

right, just RF and composite

#

but it was a good composite, among consoles

Yeah, if you were going to have a mod installed, I would advise the Turbonanza, because it adds S-Video as well as RGB

The quality of the RGB output is of course excellent, but the wrong color plate conversion seems not only to cause color errors, but also to lose the details reflected in the picture.

It would be related to the SNAC board. PC Engine polls very quickly - faster than the open-drain I/Os on the standard SNAC board can switch. I designed a special PC Engine-specific SNAC board for that. I don't sell them, but I'm sure somebody around here does.

I can't test TurboGrafx16_20200526.rbf, TurboGrafx16_20200519.rbf, TurboGrafx16_20200517.rbf, the controller seems broken in this releases for me. In core "TurboGrafx16_20200529.rbf" the controls are working again, and i get the color glitches.

OK, that's interesting

#

That corresponds with srg320's massive rewrite to support CDROM

#

But I think I understand what might be at issue - This game is possibly the only game in the whole library to use 4-color sprites (as opposed to 16-color sprites)

#

Ah, ok. Never seen this in other games (HuCard or CD-ROM). You could be right.

grand moss
#

Well, it's a valid format - just basically unused.

grand moss
#

OK, I've done some digging, and put all the tech info into a GitHub issue.
I took a look at the code, and it's not something I can just fix quickly - the way it's written is a bit confusing to me

#

So maybe srg320 will take a look and fix it.

grand moss
#

Can you folks maybe test a fix I made ?

#

#test-builds message

(for the Fighting Run issue)

#

It fixed the issue that I was able to see - but that's all I tested. Would be nice for somebody to go further in the game and check more things to see that nothing else broke.

BTW, another person found something in Mednafen related to the SCSI I/O which I will put into the core at some point. The important fact that he found was surrounding SCSI abort signals.
Let me know if you ever see a CDROM game hang during load; there may be a fix

left merlin
#

Presuming we’re talking anything longer than 30 seconds for a hang in loading as I can’t recall any game taking much longer than that.

grand moss
#

I've received one or two reports of a hang at the load of a level in Panic Bomber I think. And there is an open case about Tanjou Debut (both are intermittent)

#

I think the Panic Bomber one was fixed though

left merlin
#

Somewhat peculiar that seemingly no other Super CD games have had load hangs, especially these two don't seem taxing on the system like late system releases sometimes can be

grand moss
#

Well, these don't either, most of the time. The operating theory is that there may be something around handling SCSI that is different. In particular, one of the things that was found to be implemented incorrectly in Mednafen (and likely MiSTer) was how to deal with the SCSI Abort command.

#

Anyway, I'm not saying that somethig is broken - it's actually the opposite: despite inconsistencies in the SCSI implementation, the games all seem to work. I'm just asking you to keep your eyes open for oddities

I’m using the new core and playing TG16 games like normal just to see if it’s all working solid and so far so good.

I switched to the new core last night. So far so good. Although my attention span for Fighting Run is very limited.

No issues on that or other games so far.

If you swap to a 1.0 or 2.0 pce bios, you get a crazy mini level with prerendered 3d graphics.

You can just get the same effect by sticking that bios rom in your game folder and calling it cd_bios.rom

Developers used to hide easter eggs in PC Engine CD games if the game detects compatibility issues, like unique illustrations or messages.

Similarly some of them also have hidden messages if you put a game into a CD player and try to play the first audio track.

I never had a CD player that would even try to play track 2.

Also, for a fun track, try the warning on Panic Bomber.

I had a CD player that would play track 2. It was noise, and loud - but not the end of the world (if you knew enough to turn down the sound beforehand)

Actually, would be interesting to find all the variations. Probably 80% of games used the same track though.

You can pretty tell which are the "usual" track just by looking at the size of it

I think he was implying that was the case with mulitple makes. From my perspective, I have a vague memory that only the oldest players (pre-1986) would not mute the digital tracks

Ours were early 80s to late 80s with only a few from the 90s. Denon, Sony, and Yamaha were the most common ones but I can’t recall all of them.

Hello everyone, I try to play two player with two usb pads, when I start the core the first on shows the p1 popup and if I then use the second a p2 popup appears but in game only the p1 controller controls both player 1 and 2. Any idea what could be the issue?

grand moss
#

You have to Enable Turbo Tap. The original system had one controller port, and required a "tap" device to be able to split it out to more controllers.

Great, thanks a lot!

Does anyone know if this graphical glitch in the water of Rondo of blood stage 2 is a known issue in the turbo core? Or is it just my rom?

# stiff lotus Does it happen on original hardware?

Can’t confirm myself but I don’t notice it in this YouTube video of the same area on og hardware

https://youtu.be/cTQ814dW5Xw?si=IYAu92hKYd3cWtg4

There are actually 2 alternate paths here in Stage 2', with both of them leading to Stage 3'.

Both Richter & Maria can take the first one, which is a boat ride with the Ferryman. However, because of Maria's double-jumping abilities, she and only she can take the second alt path. You can find this within the lower section of the bridge before yo...

#

I can confirm that it’s not present in the psp/ps4 port as well

stiff lotus
#

I wonder if using a CRT somehow hides the error. @grand moss knows the TG16 inside and out.

#

But thanks for doing the proper due diligence.

cosmic wasp
#

I have no CRT to test but if any of you guys have one and can get to alt path stage 2 to see if it’s noticeable I’d appreciate it

#

Not that it probably matters but I tried out every filter available on the mister video settings and it never went away

stiff lotus
#

That’s a good test too

grand moss
#

That looks similar to the effect that they were using on level 5 to make the water's surface shimmer

#

I can't say one way or the other whether real hardware does that, but I do expect that if I remove this, it would also remove the shimmer on the suface of stage 5

#

So basically, I don't think you can have your cake and eat it too

Their core isn’t as accurate as the MiSTer one so be aware as you do your comparison.

At the time, the unofficial Pocket core (ported from MiSTer) still had a few things to fix, but it was miles ahed of the Analogue Duo product

Yeah, but it really had appeal to its core public.

Aside from the MiSTer core being as good as it already was when the A.Duo was coming out, already having a few variants of original HW, seeing their design with a slot loader was my sign to avoid it.
I’ve seen slot loader trouble before and I wasn’t gonna risk my PCE discs to that potential problem.
Wasn’t there an issue where its drive scratched up discs originally? Something like that… Until a FW update resolved it.

Too late for me and that should be something quite easily checked on QA way before the initial run.

It works great with reflex. It's much bigger than the normal pce controller. Both turbo speeds work but i dont know how accurate they are compared to a real pce. the III button is a mirror of either select or run. The switch lets you choose.
