DMC/PenC firmware mod webapp

[jaunty hemlock]

@tight ore @pallid musk @remote juniper and many other folks have contributed to software so that users can modify their DMCs/PenCs. However there are still users who aren't familiar with command line. Also there is no unified tool to do a hashcheck, update sprites, character stats and quest mode altogether.

This project aims to build a web app that allows user to:

1. Upload their BIN file to check whether it's valid and what version of firmware it is
2. Allows users to upload sprites that are of the same size as the original
3. Allow users to update stats of characters
4. Allow users to update quest mode data
5. Rebuild the BIN file and download it to users computer

The app is still really raw and might have bugs. There are still alot of functionality from the DigimonColorSpriteTool.exe that has not been ported over yet. I will work on it when i have time. Happy to have folks submit pull requests to improve this app. Also happy to take feature requests.

Support

• DMC 1-5
• PenC 0-5

[pallid musk]

Wow, this is a great idea. I really hope it takes off successfully!

[remote juniper]

penC bin file is not recognized.

It recognizes up to dmc.

And I don't know how you plan to handle the Digimon image size, but I know that the maximum output resolution of the LCD screen is 128 x 128. I think there may be a limit to the resolution.

Anyway, it's a really awesome app.

[jaunty hemlock]

I don't have a penc at the moment so can't really test. Only have tested on dmcs😅

[jaunty hemlock]

For the image size right now I only allow image that's the same size as the original sprite.

I might add support for images up to 48x48.

[jaunty hemlock]

PenC support added 🙂 thanks for helping @remote juniper

[cobalt meteor]

Gave +1 Digi-rep to @remote juniper (current: #102 - 12)

[azure moat]

this is really sick!

i noticed a bug though, when you're editing stats, the attack sprite is displayed incorrectly. if you click edit, change nothing, and stop editing, it'll correct itself.

after hitting edit twice:

[light coyote]

Godspeed man, this is huge

There's on thing with the attack sprites tho, they aren't displaying correctly

I'm guessing it's because there wasn't a +1 value added to the read

For example, if we want to use sprite 3, we are supposed to subtract it by 1 in the hex value (so we put 2 instead of 3), but I'm guessing in the app it is being shown as the subtracted version (which means they read it as 2). It's not a big issue, the web app is great, but this could be looked into for better accuracy.

[jaunty hemlock]

@light coyote @azure moat - issue should be fixed. can y'all try again

thanks for the bug reports 🙏

[light coyote]

It's fixed! Thanks a lot!

[azure moat]

thanks! looks like it's still broken for alt attacks though

[jaunty hemlock]

okay will check

bug found - deploying fix. try again in 1min or so

@azure moat

[azure moat]

thanks!

it looks like it's not validating my clean dmc v2 dump though. v1 and penc v1 worked fine, but those 3 are all i can check right now

[jaunty hemlock]

issue should be fixed in abit. updated the hashchecks for the dmcs

try now @azure moat

[azure moat]

thanks for your work dude, this rocks

[light coyote]

Are there plans to be able to edit lifespan?

[vague comet]

wdym? the duration it takes to evolve? its there to edit

[light coyote]

No, the lifespan, how long it takes for digimon to die

[vague comet]

thats still the same. they start dying when theyve reached their max lifespan

5 cms after their evo limit and they die

[light coyote]

Ahh, got it

[vague comet]

if you want your mon to start losing hearts much later than normal then youd want to edit the evo time

[hard bobcat]

Thank you for your dedication, which has benefited many people who want to do DIY.👍

[jaunty hemlock]

all kudos go to the good folks who reverse engineered the firmware. I just created a ui for it 🙂

[north ginkgo]

super impressive!!

great to see modding becoming more accessible for everyone

[jaunty hemlock]

Quest mode editing feature coming soon 🙂

[jaunty hemlock]

Quest Mode feature has been launched @ https://dmc-mod-app.pages.dev. Have fun modding guys 🙂 and as always report bugs if any!!

[remote juniper]

Do you know the location of the evolution condition part or the evolution related part in the binary file?

[tight ore]

It's code driven. Unless you're going to build a compiler in there, it'll be difficult to change

Not that it's super difficult for this limited scope, but would still take a modest effort

[hard bobcat]

Bro.The Quest Mode has bugs, and the saved IDs are in a random order.

When I update the images, the Quest mode is changed.

[jaunty hemlock]

I don't really understand. Can you share screenshots? Or explain further @hard bobcat

[hard bobcat]

When I update the images, the enemies in Quest mode will change as well.

[merry wave]

SHINKA!

@hard bobcat has evolved into Child!

[tight ore]

That doesn't sound like a problem

If it updates the same sprite that you've just replaced, that's what's supposed to happen

The slots are fixed, there's no concept of a particular mon

Well, not strictly true because you should be able to change the starting sprite ID for a given mon, but that's still something you have to edit

[hard bobcat]

This is the original version V0.

This is the v0 version with the new image.

This is what it looks like after I opened it again after building it.

The order of the enemy's appearance has been disrupted.

@jaunty hemlock

[tight ore]

That looks like a write error since you can also see one of the patterns being missing

[jaunty hemlock]

yeah there's a bug with writing the quests. i'll update. thanks for reporting

[hard bobcat]

It's nice to be able to help. Thank you for your work.😊

[jaunty hemlock]

found the bug

changes deploying in 5 mins or so

issue fixed @hard bobcat

[light coyote]

There's another thing with the quest mode.

dmc and penc quest mode both allow for every stage to have up to 5 battles, though the PenC does not use more than 3, are there plans to update the webapp to be able to add additional enemies to stages that have less than 5?

They could be made just empty spots by default

but having the option to add to them would be nice

[light coyote]

this is what I mean, there were 4th and 5th slots that go unused

[jaunty hemlock]

Oh that's totally doable will add that in

[remote juniper]

I just need to know where these values ​​are located.

I've been looking for it for a while now

[tight ore]

They're not "values". It's code

[remote juniper]

Isn't that where they are located in the binary?.

[tight ore]

No? It's literally if/else statements compiled to machine code

[remote juniper]

I lack a lot of basic knowledge.

So, does that mean we don't know where those codes are located? Are they distributed?

[tight ore]

They certainly have a location, but unless you're going to compile/assemble new code, there's not much point knowing where it is

I suppose if you're really enterprising you could edit the values to the comparisons inline, but that's a really tedious way of doing it, and you'd still need an assembler

[remote juniper]

Here's an example of what I'm trying to do:
I'm looking for evolution-related code,
so that when an existing A evolves into B under certain conditions, it becomes C instead of B. I thought I could just put B's slot value into C's slot value.

[tight ore]

First you need to disassemble the code, then map out the variables it's referencing, then edit the assembly, and reassemble it

[remote juniper]

Oh my gosh

[tight ore]

Or, you could write a new function in C, compile that, and reinsert. If it's too large, you'll have to find space somewhere else, and then patch the calling references, or patch the start of the original function to jump to your new function

[remote juniper]

I guess I should try something like that.
First, I think I need to find where that 'code' is.

[tight ore]

Throw the whole thing into Ghidra and start looking at everything

Then learn the conventions of how the compiler generates output. That helps with figuring out how things flow

[remote juniper]

Thank you very very much.

[cobalt meteor]

Gave +1 Digi-rep to @tight ore (current: #2 - 430)

[jaunty hemlock]

lol this is so tough tbh. i code but reading ghidra output is like solving a puzzle and guessing what each un-named function and variable is doing😅 @tight ore do you have any tips to make searching for things a little easier?

[tight ore]

Name every global variable

Be prepared to read and understand assembly, because the current SLEIGH definition causes issues with several constructs

I generally disassemble the code into a listing with unidasm so I can text search references, because Ghidra doesn't handle far pointers properly and you'll be mostly missing the references to those

[jaunty hemlock]

thanks for the tips i'll try hahaha! this is way out of my comfort zone, but i'm kinda excited. i spent money on digimon, and i'm learning a new skill. good investment 🙂

[jaunty hemlock]

this has been implemented. enjoy 🙂

[merry wave]

SHINKA!

@jaunty hemlock has evolved into Child!

[light coyote]

Great! Thanks!

[hard bobcat]

When I open output.bin, the Quest mode goes black.

@jaunty hemlock

[jaunty hemlock]

what did you update in your bin @hard bobcat

[hard bobcat]

Just like last time, I updated the same image and then built.

[jaunty hemlock]

should work now

[hard bobcat]

Thank you, everything is normal now.

[merry wave]

@hard bobcat has leveled up! (3 ➜ 4)

[jaunty hemlock]

@tight ore when using unidasm to disassemble which architecture do you use? unsp10 / unsp12 or unsp20?

[tight ore]

2.0

[light coyote]

Found another bug, the quest mode edit screen goes black when you try to edit a bin that has had it's quest mode edited before

[jaunty hemlock]

@light coyote - not happening for me. what specifically did you edit?

[light coyote]

Added digimon to stage 1 of quest mode

Edited power to those and swapped some around on stage 1 and 2

I can still edit stats and sprites

[jaunty hemlock]

which device?

if you can take a screenshot of what you updated for quest mode it'll be great.

else its difficult for me to find out what the issue is

[light coyote]

I'll try and replicate what I did, give me a second

It was on a modified Deep Savers bin

But the version before quest edits still reads normally

Never mind, I just got the same black screen

Just tried this edit on a bin with evolution paths edited but vanilla sprites and it worked

Then I tried the same bin, but this time with the sprites swapped, and it didn't work, despite having worked in a previous attempt

I'm guessing it has to do with the altered sprites, since it also happens with Wind Guardians. But I was able to edit the quest mode of both versions with altered sprites before this started happening

[jaunty hemlock]

I still cannot replicate this. I tried the following from a fresh bin file

1. updated sprites for characters
2. updated stats for characters
3. updated quest mode by adding characters and changing characters and editing power handicap and pattern

built and download the file and reupload again and go to quest mode. have not had any issues so far

hmm i'll need the exact steps you took to generate the bug, else its so tough for me to replicate

[jaunty hemlock]

Can you try with this older version of the app (https://aef809a6.dmc-mod-app.pages.dev/). If it works, means i must have introduced some bug when implementing new featurs

[light coyote]

Same thing happens

Must be with my bins then

[jaunty hemlock]

yeah its probably your bins

try starting from a fresh bin

[light coyote]

Yeah, a fresh bin worked, but the same bin worked so long as it had the original sprites

I'll try getting the problematic ones, swapping the new sprites for the originals, then I'll try again

Same thing even after the vanilla sprites are in, I'll just go fresh then.

Thanks for the help btw!

And sorry for having you go through all this troube

[crystal perch]

very cool app!
can the app verify penC wave 2 now?

[jaunty hemlock]

Yes it does

[limber pond]

Once we change the Mons sprites, can we change the attacks sprites ?

[jaunty hemlock]

Yes

[limber pond]

Because when you swap to a new Mon it’s obviously not the right attack so how can I change that ?

Ow yes got it 👍🏼

[arctic kettle]

Does this work after the sprites have already been modified once? For stats exiting and quest or no

[jaunty hemlock]

Should still work

[limber pond]

If we modify the sprites and stats and attributes it will still remain the same in the program, isn’t it ?
So if I fight another digivice or send my mon on w0rld or NacaStorage it will still act as the original mon from the official program

[jaunty hemlock]

im not sure i don't play w0rld or use NacaStorage. you'll probably need to ask them. but if you're battling on your own device or fighting another device, the power stat should be reflected as the updated stat.

[limber pond]

Yes all modifications worked perfectly on the device or interacting with other DMC or PenC of on that side it’s perfect

[jaunty hemlock]

Added a new feature to patch your firmware with mods by @sand glen (check here for more details https://discord.com/channels/761581682686951455/1282139224283549746)

hmm are you sure you've not modded that firmware before? I tried uploading my own penc4 bin and it works fine

[merry wave]

@jaunty hemlock has leveled up! (4 ➜ 5)

I'm having the same problem. It's a penc v4 bin extracted from Wind Guardians that just opened, and I get the same message. Is the problem solved?

[crystal perch]

yes, it fixed

[hybrid seal]

Oh, what was the problem? Did you extract the bin file again and solve it?

[merry wave]

SHINKA!

@hybrid seal has evolved into Baby I!

[crystal perch]

may be report to @jaunty hemlock said his v4 bin corrupted so i sent my bin to him and fixed the issue. maybe you could send yours to him to have a look

[tight ore]

Looking at your hash check for the latest three Pendulums, your regions are wrong. It's supposed to be code, sprite, and tail. Yours is cutting across the code region.

[jaunty hemlock]

ah right. that's a bug. i used the same regions as dmcs... will fix. thanks for the bug report

[cobalt meteor]

Gave +1 Digi-rep to @tight ore (current: #2 - 440)

[jaunty hemlock]

Updated. Issue should be fixed

[earnest wave]

🤔 thats weird. I’ve never had this issue with any of the pendulum color dumps.

Even before you updated.

I wasn’t really sure why people were saying they got an error with WGu dump. I tried it multiple time on the web app using a freshly read WGu dump, never had any issues

I did however got the modded firmware notification once with a MEm dump, but i decided to do a read again, then it was verified good.

[jaunty hemlock]

lol I basically did a copy pasta and forgot to update the regions. So I built the hashes using the dmc regions instead of penc ones. Although it works but it's not the right logic haha. Now it's fixed

[earnest wave]

Hahhahaa

Good to know

Thanks for the update man.

[earnest wave]

Hi, i'd like to report that the quest mode edit kinda doesn't work with the 3 most recent pendulum releases.

i modded the quest mode on one of my devices and it still ended after 3 battles for the first stage eventhough i've setup 5 digimons.

[cobalt meteor]

Actually, the plural of Digimon is- GUNSHOT

[jaunty hemlock]

@earnest wave have you tried with the wave 1 releases before? if yes, did it work for those?

[earnest wave]

Nope, just verified with a friend who i modded his NSp. And he confirmed, it doesn’t go to the end.

It works for the DMC though.

I can only test on wave 2 penC. But i think if it works for the wave 2, it should work for the others.

[jaunty hemlock]

It might be possible that pencs just don't support 5 enemies. I referenced what @light coyote mentioned about pencs possibly supporting it so I added that feature.

@light coyote - did you manage to test whether 5 enemy quest mode works for pencs?

[earnest wave]

sorry my mistake

nope

[jaunty hemlock]

Okay then i think it just doesn't work. I'll remove that feature then

[earnest wave]

alright. i think the penC limits it to 3 enemies

[civic holly]

How bizarre that it has the space but not the function

[light coyote]

I hadn't tested, I've been cyclying through different mods testing things. I'll try it out and see

Gimme a sec

[arctic kettle]

Any progress on adding larger sprites? I know we can through cyanics tool but would be amazing with your incredible UI want to test some without manually packing each time! Appreciate you’re amazing work!

[jaunty hemlock]

Working on it. Been busy with real life stuff recently 🥲

[arctic kettle]

Completely understand thankyou! Good luck with everything in life sending good vibes

[sand glen]

There’s a variable you can adjust that would allow you to use more than 3 enemies per stage, but it’d apply to all stages. So if you make it 5 then every stage needs to have 5 enemies.

If you allowed it to be adjusted you’d have to make sure to set a hard limit of 5 and not allow the bin to be modified until all the stages had been filled with the appropriate amount of enemies or the user would likely experience a crash

[earnest wave]

Hell yeah, i always thought the 3 enemy per stage thing is too short.

5 enemies all the way

I think you could allow the users to set their own amount of enemies but it applies to all the stages before the user begins to perform any changes. For user who enjoy only battling 3 enemies, they would just choose the option to have 3 enemies on each stage. But for those who love a bit of challenge, you could probably let the user set the number of enemies to 5 for those and validate if all slots are filled up before proceeding to build the new bin file.

[earnest wave]

Also, i’ve noticed a lot of people have used the web app to modify the power of their digimons and bringing the devices to our local tournaments. I had to check 15 devices in our last tournament and 9 out of those 15 devives had all their digimons power set to 500.

[cobalt meteor]

Actually, the plural of Digimon is Mon Mon Digimon Pendulamu

[earnest wave]

Maybe it would be a good idea to limit the maximum amount of power you can assign to a digimon based on its evolution stage. For example 50 for rookies, 70-80 for champions, 95-120 for ultimates, 130-180 for megas and 200-205 for SU.

This will greatly help with tournament pre checks and validations on modded firmwares.

Plus having a beast that can take out everything you throw at it in quest mode really defeats the quest modes purpose of giving a small minigame challenge for you to complete imo.

[jaunty hemlock]

Removed feature to add 5 enemies for PenC until exact variable to edit is known

[jaunty hemlock]

What if the Character ID is set to 65535 similar to DMC?

[tight ore]

It requires some minor but not trivial modifications. It's currently hardcoded to 3 battles per quest stage, so you'll need to insert additional logic to check how many there are

[sand glen]

Yeah, like cyanic said you’d have to add custom logic to tell it to stop when the enemy data is a certain value. Otherwise you can change the hardcoded value from 3 to 4 or 5 but that will apply to all stages

[merry wave]

@sand glen has leveled up! (8 ➜ 9)

[earnest wave]

Awww man, the only thing i hate more than ambiguous error messages are hard coded values. Hope you guys find a work around for it and thanks for all the hard work you guys have been putting into this project.

[cobalt meteor]

Gave +1 Digi-rep to @tight ore (current: #2 - 442)

[earnest wave]

Amazing stuff you got here.

[sand glen]

Hardcoded doesn’t mean it can’t be changed easily

It just would be for all stages. To make it variable wouldn’t be much harder either, I think I’ll try my hand at it at some point.

[earnest wave]

I guess this is why the penC only has 3 enemies on every stage.

I know its not that hard to change hard coded values to make it variable, but i just have PTSD from the data management job i had back in the day.

I was tasked to remove every hard coded value within a system and to change it to a variable that can be retrieved from a database.

[jaunty hemlock]

You can now upload larger sprite sizes. Enjoy!

[remote juniper]

huh?

[earnest wave]

Ohh yeahhh. Pendulum progress sprites, here i come.

[remote juniper]

Are you saying that an image larger than 48 48 size can be included?

[remote juniper]

As the size increases, the data location gets pushed out. How do you implement that?

[jaunty hemlock]

there's still quite abit of space for the sprites

i have error handling such that if the sprites added exceed the flash limit it'll throw an error

[earnest wave]

How big can the sprite be?

[remote juniper]

So what size is currently possible? And how does the game console output it when you put in an oversized image?

[jaunty hemlock]

@remote juniper - i have not tried for sprites where the height is greater than 48px. But i've tried for sprites where the height is 48px and the width is greater than 48px

[remote juniper]

As you can see, images that are multiples of 16 in size are meaningless unless they are larger.

Is there still a function to change the resolution?

[earnest wave]

Its beautiful

[remote juniper]

wow..

[jaunty hemlock]

the one i showed above is 58 width 48 height

[remote juniper]

Whats that sprite size?

[jaunty hemlock]

i resized vb sprites

[remote juniper]

wow

we can convert vb sprite

How nice

It's a shame that it's cut off, but I'm satisfied with this.

[jaunty hemlock]

i have not tried for sprite sizes greater than 48px height. I'll try now and see how that goes lol

[earnest wave]

Im just soo happy that i get to see all this being made and working.

[remote juniper]

I already tried that

[earnest wave]

I feel like a kid again

[jaunty hemlock]

what happens? @remote juniper ?

i'm thinking whether i should just put in error handling to prevent people from uploading sprites > 48px tall if its a character sprite

[remote juniper]

From what I remember, it goes all the way to the UI part. I think there must be a picture of it. Just wait a moment.

[earnest wave]

I think this is best.

[jaunty hemlock]

Actually @boreal vapor shared with me that the idle animation sequence can be edited. So if you want your VB sprites to not get cut off at the edges of the screen its possible by editing the animation sequence X position

[jaunty hemlock]

I'm working on adding the animation editor into the app, but that'll take awhile

[remote juniper]

You seem really awesome

These are the features I wanted to implement.

[earnest wave]

Looking forwards to this, take your time.

[jaunty hemlock]

wip - only render the animation so far. editor to edit frame by frame will come at a later time

[earnest wave]

This is even cooler than what i imagined. Cant wait for it to release

[boreal vapor]

I have recently managed to find a way to expand the sprite size limit thanks to @sand glen's help

the only problem at the moment is that if you apply it on every Digimon in PenC, it will increase the rom size, so we will be finding a way to remedy it

[cobalt meteor]

Gave +1 Digi-rep to @remote juniper (current: #88 - 14)

[tight ore]

There's only one animation that uses a table for its frames. The rest are all in code

As for sprite size, can probably reimplement what's used on Tamagotchi Nano Colorful, though the chip they use is more suitable towards that particular implementation

[boreal vapor]

I take it it's only the idle animation at main screen right?

[boreal vapor]

also that was on me, I suggested him to suggest you that, soon after we found out that it's not possible to make it 5 enemies unless we update some code first but forgot to let Phrog know about it

[jaunty hemlock]

lol all good. it's good that we explore to see what's possible:)

[jaunty hemlock]

[ New Feature - Ability to edit idle sprite animation ]
You can now view how your sprites will move on your device and make changes to their idle animation to your liking. Thanks to @boreal vapor for sharing the hexpat for this and contributing to this feature

[hard bobcat]

Can the movement frames of Digimon on the device be changed?

[jaunty hemlock]

what does this mean? Like what's shown above? Or sth else?

Cyanic mentioned above that the only animation that can be edited without messing with the code is the idle animation of the mon walking on the screen.

[boreal vapor]

if your question means changing the frame for the idle screen movement, then yes

[boreal vapor]

and I thank both @faint shuttle and @sand glen for helping me find the hex address for the idle animations

[cobalt meteor]

Gave +1 Digi-rep to @jaunty hemlock (current: #113 - 11)

[hard bobcat]

That's what I meant, thank you.

Thank you for your hard work.

[faint shuttle]

Glad to have helped!

[limber pond]

Hey guys I was wondering
Can we modify the shaking 🫨 count of the mons on the PenC ?

[merry wave]

@limber pond has leveled up! (4 ➜ 5)

[boreal vapor]

I remember there's a way but we'll have to look into it first, but not sure if it's a simple hex change or recompiling involved

for now I can say that the shaking count is not based on individual Digimon, but rather based on attribute

[tight ore]

It is a table IIRC, so probably

Try searching for posts from me in #modern_vpets, I've described it to some extent

[solemn grail]

So this just modifies what currently exists in the bins. Is there no way to expand the functionality of this to increase the roster size of bin?

It is cool either way.

[jaunty hemlock]

Wait for cyanic or kurozatou to release their patches for this. This app doesn't do that.

[solemn grail]

Sounds good. Was just curious if this was going to expand into that territory

[earnest wave]

Take you time guys. Im sure it’ll be awesome once its released

[solemn grail]

For sure!

[twin heath]

hi!

why does it says modified version detected?

did i do something wrong?

is my first time doing this, i extracted the .bin and uploaded here

[latent pike]

Mine doesn't show up like this, but when I flash the program, the screen goes green. At first, I was going to go in and fix the attack moves. I don't know if there's a problem with Vpet.

[merry wave]

SHINKA!

@latent pike has evolved into Baby II!

[twin heath]

nevermind this, this look like a bad read

i got it correct now, thanks!

[vivid pike]

Hello
I loaded the modified DMC bin, but some of the images seem to be displayed incorrectly. Does this have no effect when writing to DMC only on the web?

[jaunty hemlock]

Hmm not supposed to happen. If you see your sprites messed up you might have a bad flash read.

Suggest to re-read your bin file

[vivid pike]

thank you
I'll try loading it again

[hollow sand]

Could you add a dump all images option?! Always worried of storage failure and a dump all as a back up if you have the bin would be amazing! Regardless thanks for your amazing work for the community!

[vivid pike]

thank you
When I read the file again, it was displayed correctly.

Detailed Changelog
Character Stats Tab

1. For the character stats edit screen, the edit button used to be at the end of the table. But this is used pretty often so i moved it to the start of the screen so less scrolling is required
2. You can now click on any editable data to start editing it instead of scrolling to click the edit button. Once again to reduce scrolling to find the edit button
3. When you have completed editing, you can click enter within a cell to save that row's data. Once again to reduce scrolling to find the edit button
4. You can now sort by certain columns. This is helpful for situations where you want to preview sth like the album sequence

[twin heath]

you are THE GOAT

i just realized you are the same guy doing the VB sprites repository, thank you for everything!

im doing the builds with your program, is super easy to manage, now even more

[hollow sand]

Works like a charm awesome amazing work man! You are so awesome the community loves and appreciates you!!!! #Legend

[azure moat]

Just wanted to pop in to say thank you for your work on this! This is seriously a game changer and I love I can do most of my modding through one app rather than the several I've been using up until now. Looking forward to future updates and thank you again for the amazing contribution to the modding community!!

[earnest wave]

This has honestly saved me hours of modding for my kids. Thank you for all the hard work @jaunty hemlock

[slim brook]

I have been pretty out of the scene, does this support editing the evolution trees/requirements?

[twin heath]

just stepping by to say that getting all sprites while you build is a genious move

thank you again @jaunty hemlock this is awesome and keeps getting better 🙂

[jaunty hemlock]

Nope it does not

[solemn grail]

Question, so the only way to upload images for the sprites is individually? There is no option for just uploading the sprite sheet for a digimon?

[jaunty hemlock]

You can upload multiple individual images. Supporting sprite sheet is tough because there's so many different sprite formats with different sizes and different borders and different sequence of animation. Probably need to build like a wizard to guide user through uploading spritesheet, choosing dimensions, selecting sequence, checking output before uploading and also adding error handling for ppl who upload invalid spritesheets. Could probably do it if I had time but lol been pretty busy lately

[light coyote]

You could just set it to read the standard PenC format

Tortoiseshell's sheets are in that format

And Cyanic's tool can export penC sheets like that

The DMC can use the same format, since it uses the same frames, just with some repeats

I don't know how difficult all of that would be to set up, but there is a standard format for both PenC and DMC

[solemn grail]

I am no developer so idk how feasible something like this is, but what if you could highlight the sprites you want to change and have them be swapped with sprites that are in the standard pen c and dmc format?

Either that or a tool that can slice the images in the spread sheet apart and then let you download them as folder of pngs. Then you can just label them that way and do the import.

Idk just thoughts

[tight ore]

One problem with file multiselect is they often don't remain in the same order as selected

A sheet cutter shouldn't be too difficult. Just specify numbers of rows and columns, slice it up, and scale up if necessary

[solemn grail]

Good point. I assumed that the sprites in the bin are order roughly the same as as the pen c format/dmc format ( idle, training, attack etc) so I thought it wouldn’t be crazy.

[merry fog]

This is my 1st time using this app and I got this notification. Do I have to use the original bin file and start all over again?
Before this, I asked my friend to mod my device and he used a different software

[vivid pike]

It simply indicates that it is a modified bin file.

[merry fog]

Ok. So it's still gonna work if i continue building the modified bin file right?

[vivid pike]

Yes, that's right.

[merry fog]

Thank you!

[cobalt meteor]

Gave +1 Digi-rep to @vivid pike (current: #425 - 2)

[earnest wave]

Yes and no really. If you are sure your modded rom dump or read is good and you are 100% sure that everything is in the correct order, then there would be no issue.

If the dump/read turns out to be corrupted, then you might get some weird glitches and bugs when you ultimately rewrite it to the chip.

The best way to know a read is good, is to take multiple dumps of the original firmware and test out each one and to only use unmoded roms to make any changes so you are sure your dump or read is good before proceeding

[merry fog]

So i need to use the original firmware to mod? Means that i have to start all over again from scratch

[earnest wave]

You don’t have to per say, but its best because you can check if your read is good or not

If you are good with hex codes and can verify that the modded dump is in order and will not cause issues, then go for it.

Thing is, with a modded roms, its kinda hard sometimes to verify if everything is in order since modification have been done to the file.

[earnest wave]

This notification could also mean the read that you took wasn’t a good read.

Its too hard to tell why you got that notification exactly.

since you also said the firmware is a modded firmware.

[merry fog]

Well, the thing is, i'm using modded dmc and penc right now. I don't know how to mod but i know how the dump files work like the correct numbering of the images. So after i sorted out the dump files, i'll send them to my friend and he'll mod them by using different software from this one. Recently he sent me the modded bin file and thus the notification

[earnest wave]

Yeah, thats probably why.

[merry fog]

So it's better for me to drop the original bin file and edit it from this app right?

[earnest wave]

This is best since you get the green notification that indicates everything is working properly and will produce a good bin file once you are done.

[merry fog]

Ok. Thanks bro

Good luck and have fun.

[muted pasture]

do you know if there is a plan to add such things? including just adding to the tree?

[jaunty hemlock]

I will add them to the webapp when the big brains who reverse engineer the device release these feature.

[twin heath]

does this support, or will support monster hunter DMC?

(i dont have mine yet but im eager to tamper)

[tight ore]

It probably won't out of the box because there are extra sprites to deal with

And it also needs to handle right facing sprites for a few characters

And potentially running out of space

[twin heath]

understandable, thanks!

[jaunty hemlock]

Thank to @tight ore and his work on reverse engineering the MHC, there's a beta version of the mod app that supports the MHC. I have not robustly tested this so there may be uncaught issue - do let me know if you face any issues. If there are no bug reports for the next two weeks, this feature will go into the main app page.

As mentioned by @tight ore as well some characters have 20 sprites instead of 15 sprites so do take note of that.

https://mhcdemo.dmc-mod-app.pages.dev/

[lean drum]

My devices arrived today! I’ll be checking this out in the next few days, so I’ll let you know!

[lean drum]

Thank you 🙏🏼

[jaunty hemlock]

Added some checks to ensure that BIN file does not go over 8MB (8388608 bytes) which may happen if you add sprites that are too large

[tight ore]

Probably check for 0x7fd000 instead so you don't go into save data territory

I don't have that in mine because some people can use extended size chips. Although maybe I should make sure to carve out that space so sprites don't get written there

[jaunty hemlock]

Good point - will do that! Thanks 🙂

[jaunty hemlock]

This is amazing. I hadn't fully come to grasp just what this tool could do since it came out when I was checked out of Digimon stuff.

Absolutely phenomenal work

[obtuse elk]

I'm still having issue putting in the mh bin? Is it the way that getting bin are different with dmc?

[obtuse elk]

Oh my bad, I'm using the wrong link

[faint flax]

I'm currently having issues downloaded an edited bin file
I click on build and nothing happens. Is it supposed to take a bit before giving me a download link? I hope I'm just being impatient 😅

[jaunty hemlock]

It takes awhile then it downloads as a zip file patched_bin.zip to your downloads folder

[faint flax]

Thank you for the confirmation, I was just being impatient as evident by all the things I changed 😅

[devout swan]

@jaunty hemlock the attacksprite is 24x24
After changing the attacksprite bin file, the machine cannot boot up.

[jaunty hemlock]

i'll take a look

can you share with me which version you were using

[devout swan]

penc v0

[merry wave]

SHINKA!

@devout swan has evolved into Baby I!

[jaunty hemlock]

I'll dm you

[blazing elk]

I'm getting the same issue with DMC V5 after changing some sprites and AtKSprites for my kids DMC V5 it won't boot up...Tried three older bin Files BaseV5Bin/V5HDBIn/V5CustomBin all loaded fine...but the new one I made yesterday won't boot.

[jaunty hemlock]

There was some bug ytd

Try again - it should work today

[devout swan]

@jaunty hemlock excuse me bro, one question again, can enter the Chinese name in to the this mod?

[jaunty hemlock]

Not my mod, but from what I understand only A-Z is supported from the documentation

[devout swan]

[lean drum]

I've been trying to use an English mod for my MH device with sprites used from a project here, and even on a clean save, I keep getting an error saying that one of my images are the wrong size. I've narrowed it down to the actual names of the monsters are the ones that are bugged, but when looking at both images, I don't see anything wrong with the height and it doesn't appear that length is a requirement, so just not sure what is going on here, hoping some one could point me in the right direction as to what to try out next

Error I’m receiving

[jaunty hemlock]

I just tried and it works. My app does not have a dimension error alert anymore ever since the new mhc support update. It just shows a warning if you upload a sprite that is greater than 96px in width. My guess is you're using a cached version of the app.

Either open the app in incognito mode, or just clear cache and refresh your browser

[lean drum]

I’ll give it a try, thank you!

[twin heath]

sorry to bother @jaunty hemlock but how do we edit attack sprites now?

i know in past version of your edit tool you had attack sprite ID to edit on each digimon, in character tab

but now i can't seem to find it

nvm im dumb i just had to scroll right

[winged parrot]

Bumping just so it appears in my threads.

[pallid musk]

pinning top post so it's easier to find

[twin heath]

ok, ill post it here in case someone met the same problem as me

i have a penc+ (kurozatou's mod) virus busters already parched and working , i reflashed it and it works flawlessly

but when i use firmare mod webapp to edit it, penc doesnt even start

i only changed sprites , digimon names, and some type (virus, vacine data) nothing more

i already used this program a lot before and never had a problem, edited a lot of DMC, and never had a problem

so, i think problem might be in name or attribute name change?

have anyone encountered simmilar issue?

as soon as i flash edited .bin, penC stop working. If i reflash the penc+ mod clean (without editing in the webpage) it works again

so problem might be in the name editing?

as this is the only new field, comparing to penc not modded

i also changed some attributes to match the new digimon i added

and thats it, the rest are just normal sprites

im now trying clean penc+ and only sprites, without name and attribute editing

to try to locate where the issue is

So, i did ONLY digimon sprites changes (upgraded to wonderswan/Seppu/TeroOx HD ones) and it's not even starting

maybe they are too big and the device is already too cramped with the + mod?

as soon as im back to default penc+ it works again

i changed only digimon sprites, but ALL of them to their HD variant

and it refuses to start as soon as i change them and reflash

i chaned all sprites from ID 240 to id 635 if it helps

with HD variant

and the clean penc+ .bin im editing works 100%

so its not a problem of bad .bin

reflashing is also not the problem, as i am able to reflash the penc+ base .bin without issue

maybe i can send you the .bin so you can see what's wrong @jaunty hemlock ?

thank you in advance

[twin heath]

when i load the .bin to check if there is any error i get this message, i think is normal

only change on this one are digimon sprites, from ID 240 to ID 635, nothing more. Not names, not type or other data.

[sand glen]

There’s an issue with PenC+ right now when sprites are not the original dimensions

Eventually I plan to go back and see if I can change that but it wasn’t a high priority

[twin heath]

ohh ok

ill wait for the fix

ty!

[scarlet vault]

@jaunty hemlock I thought it was working but I guess it’s not. The clock fix mod for the DMC ver 3 isn’t working

[jaunty hemlock]

Pretty busy lately - ill check to see what the issue is. In the meantime you can refer to #1282139224283549746 message for the original patches for clockfix

[scarlet vault]

Thanks

[lean drum]

@jaunty hemlock I'm having some issues with modifying my MH DMC with updated sprites. Over all, the sprites I'm using are smaller in size than the original files because I've compressed the sprites but I'm still receiving an over flash chip size limit warning. I've tried uploading the sprites in smaller batches to see how far I can get and it seems I reach about 75% of the roster before hitting the warning. The sprites are bigger (54x48) but smaller in file size, should I look at simplifying the color palette in order to help or do I need to resize all the sprites that aren't 48x48 to that size?

the base bin has an Images folder size of 1.68 MB while my mod sprites folder is at 1.12 MB.

[tight ore]

File size doesn't mean much. There's no compression on-device, so when stored as raw bitmap the sizes will be larger. There's very little free space on MH DMC for larger sprites.

[lean drum]

So I’ll have to resize and maybe simplify the color palette to fit it all in. thank you!

[jaunty hemlock]

Doesn't matter if you simplify the color palette also. All it matters is how many pixels there are. The more pixels, the more space consumed, Doesn't matter what's the original filesize of the png file as what's cyanic mentioned

[lean drum]

Thank you for the clarification!

[cobalt meteor]

Gave +1 Digi-rep to @jaunty hemlock (current: #46 - 38)

[tight ore]

Color palette doesn't matter either, it stores each color separately

I do have ideas for making palletized rendering a la Tamagotchi Nano Colorful (which uses the same base engine but handles rendering a bit differently), but not any time soon

[gleaming cedar]

?
Is there a way to edit the hatching time of the eggs in the digimon color to one minute ? To make it feel more like the original.

[scarlet vault]

No. The egg isn’t an actual stage. It’s a scripted animation

[gleaming cedar]

Ok thank you

[timber plume]

This tool doesn't support the DMC Godzilla yet, correct?

[pallid musk]

Yeah not yet

[pearl panther]

Hello! Is this website working with Pendulum Color Plus ?

[timber plume]

Yep, it does!

[pearl panther]

Nice thanks!

[pearl panther]

In the character view, how do you set wich digimon Jorgress with wich digimon and the final result ?
Is this even possible ?

[pearl panther]

What does this do and how can I know in what it will jorgress ? Can I change it ?

[civic holly]

It's this

You cannot currently change evolution pathing

So you would reference the outcomes on the guide

[pearl panther]

Ok! Thank you, that's clear! 😄

[buoyant minnow]

Portrait update dropped, not sure how hard it would be to implement replacing portraits but looking forward to it.

[hard bobcat]

teroOx is very busy, give him some time😄

[craggy ravine]

Does this app support the dmgz?

[west nexus]

See above.

[craggy ravine]

I hoped it had by now.

[west nexus]

Well, I think it would have been announced, if that was the case.

[exotic atlas]

i see the app doesn't (yet) support the dmc godzilla. I know a few people have done English patches, if not the website then how does one do this?

[merry wave]

SHINKA!

@exotic atlas has evolved into Baby II!

[faint shuttle]

Cyanic's sprite tool is the go to for me https://github.com/GMMan/DigimonColorSpriteTool

[exotic atlas]

okay I'll try it. Does it have a GUI or is it command line?

[faint shuttle]

It's command line, yeah
