ROM Hack [Release] Ultimate NES VC Injector for 3DS

[Deleted member 370283]

Managed to convert a FDS file to QD and injected it in. Can't swap sides of the disk though.

A patch is needed to automatically switch the disk's side.
Zelda II -Link no Bouken handles this by doing a few things.
Firstly, it modifies a subroutine during the disk swapping screen that is supposed to actually check if the disk is swapped. At address $8452 in memory...

LDA $4032
LSR
BCS $8442
RTS

This loads the disk drive's status register into A, shifts it right so that the insertion flag becomes the carry, and then if this insertion flag was enabled, it will branch. Otherwise, it just returns and loops, waiting for a disk.
We know already that a disk can't be inserted in VC, so the patch that is used is actually quite simple. It changes the BCS opcode to BCC, which makes the code:

LDA $4032
LSR
BCC $8442
RTS

Now even if the disk drive's status register says that there is no disk inserted, we will still branch and continue anyways.

The only other things it does is blank out the "CHANGE SIDE _" and "W A I T" screens to make things a little cleaner.
I don't know how similarly this would work for other FDS games, but I don't think it should be too horribly different. Good luck.

Just wanted to confirm, I tried both SMB2,3 EU and US, none of them is working. Will try another versions. Oh, and is that me or Duck Tales (US and EU) is droping fpss in Moon level? Music seems to be kinda chunky while jumping. And pixel perfect River City Ransom is AMAZING guys, AMAZING. I think I'll replace my whole eShop NES VC library. Except for Ice Climbers, nothing will make it better.

I think the reason why the compatibility with this is a hit or miss is because Nintendo probably has multiple NES emulators depending on the mapper? Anyhow I hope Asdolo considers making a Retroarch forwarder for NES games like he did for Genesis/Mega Drive games, since that would allow for custom button configurations (good for platformers) and overscan cropping and more accurate palette options.

why does this happen with every one of your injectors i try to use?

Try running the Injector as Admin, and also try disabling your antivirus. It may block access to 3dstool.exe.

I get errors like that on all injections, but i just press continue and it still works. Except the GBA IPS or save patch option. It never finishes.

Is it possible to maybe add download play support for multiplayer games?

 

[WeedZ]

thats just it. i did both of those things. i had the same issue with the snes one. my .net fw is updated as well.

the snes one wouldnt build at all. i just got a build with solar jetman nes by hitting continue, but it crashes as soon as you try to boot it :/. the vc still runs so i can hit home. idk..

I never managed to fix this popup, but sometimes it still completes, so i dunno, Maybe someone else has fix? He did say try disable antivirus, but i dunno if that what caused it. Did injections for Super mario bros 3 Mix rom hack. and Rockamn 4 minus infinity, so i guess is luck based?

 

[Asdolo]

Wait. Are you both using 32 bits OS?

 

[WeedZ]

Wait. Are you both using 32 bits OS?

win7 64bit

 

[Sonic Angel Knight]

Same, I never had a 32 pc system, since all the ones i buy come with 64, should that matter? I though lots of stuff was compatible with 64. I even tried different compatibility modes and run as admin.

 

[WeedZ]

im thinking the crash on 3ds is the rom at this point. i got a few builds between the errors. i tried a us copy, copyright screen then blackscreen + constant tone/crash. tried eur, copyright screen, then played a bit of music before crash + black screen. so it might have worked with a different rom. the problem is, you have to keep spamming the finish button and hope it goes.

Explain the crash? did you test the rom on emulator before injection? If you are able to load the VC menu but the screen is black, is the rom. If the VC doesn't load, is the CIA itself, not all roms can play on VC for special chip reasons, they have not supported emulation.

Most likely MMC5 or over 1MB in file size, some rom hacks won't play.

Its definitely the rom then, the console still runs. the rom works on other emulators. goddamn it, i always want to play just one game, and its always impossible. last time i spent hours trying to get zelda for snes-bs to run on vc, blarg, and snes9x-3ds.

Give me a moment, i'll try myself
what rom is it?

 

[WeedZ]

Solar jetman

 

[Sonic Angel Knight]

Solar jetman

Yeah, i tried it, think the rom is not compatible with VC, surprised is made by rare ware, published by trade west. It boot, show copyright then black screen with single sound playing as if system softlock (on real nes)

That's exactly what happened with me. Oh well. Thanks for checking it out.

 

[Sonic Angel Knight]

Also maybe when using injections, try to create the file name without spaces (instead of " " use underscore "___" So it would be "Mario's_Adventure" Like that) Not sure if it helps with the error you keep getting, but is random for me. Also i will try to find a way if it can be fixed to work on VC. Or maybe use a emulator homebrew on 3DS?

Can you try battletoads rom to see if it works? Seeing is also a rare ware/tradewest game i would suspect it also may not work on VC.

Posting rom data status for OP to see just in case he is curious.

If you find a BattleToads inject (made before this injector came up) that works, let me know, then I can make it work on the Injector
