Hacking The general VC rom injection thread (NES,GB/C/A etc.)

[zhdarkstar]

Out of curiosity, has anyone tried running PocketNES or Goomba Color via VC? I know that the concept of running an emulator within an emulator is counterintuitive, but it could be an alternative to having dozens of injected VC roms if it works well enough.

Decided to google the Camerica mapper and found out that "It's largely a clone of UNROM". There are some difficult exceptions, but Micro Machines doesn't appear to be one of them, so it works fine with this header:

544E4553062000000200000000000000

(no spaces for pasting into a hex editor, or: )

54 4E 45 53 06 20 00 00 02 00 00 00 00 00 00 00

Lol no flaws at all? No gfx glitching or anything?

Edit: can't have been very attentive the first time - yeah, there's some graphical glitches, nothing that impedes gameplay.
Is MM known for emulation problems? I remember it having glitches on my android gadget too.

I had a go at making a NES -> TNES converter. I tried to keep it simple, the code is probably terrible and ugly, but it seems to work. Zip contains the source (should compile on windows and *nix) and a mac binary (compiled on 32bit snow leopard, would presumably run on 64bit and newer os x versions). I borrowed some simple file access functions from makerom because I'm lazy, thanks 3DSGuy. It supports the mappers listed earlier in the thread, more can be added easily as they're figured out.

It runs from the command line,
tnes infile.nes outfile.nes

Feel free to share builds, make improvements, make batch files or graphic interfaces or whatever the hell you like.

lol i had just nearly finished something similar....but it was based on a python script thing i found online.....

Hey, the more the merrier

I couldn't get Qix to run, but I'm not convinced the problem is with the converter.
Also I had a first go at making a nes multi-rom, I shoved 8 roms in there but when I started the .3ds it just loaded the first one, didn't show a menu.

 

[gamesquest1]

well it seems to work as intended........but to be clear i ain't no coder, so i just worked with what i could
also it only works on headerless roms, (i.e the top line removed if it already has the "NES" header)
....so for what its worth

Needs python installed, just drag your headerless rom onto fix header.bat

 

[hippy dave]

Oh cool, using a database is nice.

Having an issue with NES multirom too. gamesquest1, how do you get multirom for nes? I've tried having "vc_rom.bin" and "vc_rom2.bin" and it doesn't work. I opened vc_rom.bin with hxd and copied everything into the end of vc_rom.bin and it's still a no go.

Tried your nes header patcher and it works great. You should probably bold the pre-requisite of having the original header removed. Took me a while to get that.

yeah its mostly plagiarism, from here http://greg-kennedy.com/wordpress/2012/05/30/ines-header-fixer/, and the data base was from here http://bootgod.dyndns.org:7777/
both slightly tweaked to the *correct* layout and mapper ID (relatively speaking)

it seems the multirom menu triggers on some VC bases and not others, there is actually version strings in the .code too, so one VC rom is not the same as another

Basically go for the smb3 VC base...it may be in others too though(well the strings for the multi rom menu appear to be in others at least...it just doesn't trigger for whatever reason)

I'm having some issues with the multirom. I got a lot of games to work, like all three Super Mario Bros in the same ROM.
I got some others working too, but when I put all of them, like 6 ROMs on the same file, some of them doesn't work, even if they work separately.

Anyone knows what is the limitation for that?

 

[alexenochs]

I don't think anyone knows the limitation but it seems your going over it

 

[Mikecrowfone]

Does anyone have a mirror for the decryption and packing tool by ground? The link in the 1st post isn't working.

I wanted to change the banner of the VC ROM I built. So I change the banner image in the Banner Maker, ran the script in the banner folder and then the script in the main folder. I changed the unique ID in the gw.rsf file and built the VC ROM, but it still shows the old banner. Anything else I have to change?

 

[gamesquest1]

did you copy the outputted "icon.icn" and "banner.bnr" into the folder you are working with for (probably decrypted\exefs if your using the tools from this thread, you will either need to rename them to "icon.bin" and "banner.bin" or exit the makerom.bat to use the .bnr and icn files instead of the .bin files

Yes, I did exactly that.

Delete the compressed.cgfx before running the banner.py script and change the UniqueID again.

That worked, thanks. So do I have to change the UniqueID everytime I change the banner images?

 

[gamesquest1]

no i think you only need to change the unique ID if you change the icon or app title, they are cached by the system, but the banner isnt, so you can change that without changing the unique ID
