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

[Asdolo]

Unfortunately, no. GBA, GBC and GB games (excluding New VC/Pokémon RBY) don't support Link Cable or other multiplayer functions. Only NES, Game Gear and SNES games do.

Actually, someone did adapt the RBY patches to makes CRYSTAL cable link functions work in an injection!

I know that already. That was Gen 2 injection of Virtual Console. Gen 1 doesn't support Link Cable in any way.

@Asdolo Turns out you are right indeed, the way you're handling it right now is as good as it gets, editing any more digits causes issues on the n3DS apparently.

The best idea would be to include a DB in there of all official 4 digit titleIDs though and just exclude them from the randomizer. (but not from the field entirely, just don't let them show up at random)

Even with 4 digits, we have 16^4 = 65536 different Title IDs.
But more than one time I got an official eShop Title ID, so I'll try to include a DB. Besides, that DB won't obviously include Homebrew or Custom CIAS

FBI Installer should warn you if the CIA you want to install already exists (in terms of Title ID).

If it'd help, I could go around and try to find a bunch of homebrew TiDS to also exclude from the randomizer and post them here in a spoiler tag for ya.

Edit: Actually, here's all the homebrew title IDs already compiled, you're only concered with the ones that actually use 4 digits so not all of them are useful to you, but it looks like most homebrews are here:

It would be great! Maybe even there is actually a Homebrew Title ID DB. 3dsdb.com does not include them?

Hello guys, I heard that I need to patch the pokemon games before make it as CIA ?
Can you tell me what I need to do exactly ?
Thanks in advance !

What do you mean by patch?

 

[HoloryTV]

Do you still have to patch Pokemon games beforehand

For now, yes.

 

[Clydefrosch]

i just edited the ids manually for now. going with something simple like A001 A002 etc, there really shouldn't ever be issues with anything official.

also, i noticed that random games seem to be using for example the X button? in sonic battle, it mirrors the B button.

finally, super monkey ball jr doesn't seem to save, mario advance 4 doesn't start due to save reasons either. damn these save types

 

[HoloryTV]

I will need to ask to @Asdolo what "patch pokemon" mean.
it must be "agb_firm signature patcher" ?

B is mapped on both B and X. It's a feature of AGB_FIRM. This way you can use B-A or X-A, which has the same orientation of Y-B on a SNES controller.
Regarding SMB3 save, I found this on a thread on that iso site

*** For the e-Reader levels to function properly, you need to boot the game once, and when you see the world map shaking, shut down your system and reboot the game. You might see a "Save data corrupted error" when booting, but the game should work as intended, as long as you keep using "File 1". There have been reports that the "Save & Quit" function might lead to data corruption, so I recommend you save at castles instead. Special thanks to skmpowdjy for the info.

i'm even using the wii u release with the e-reader levels... and while that sounds like a plan, the game starts with save data corrupted error and never gets past it. so i cant do that

Ok I fixed my white screen problem.
For those who got a white screen with pokemon games you need to use a hex editor.

@CheatFreak47

Is it possible to include functionality that would allow for editing names / banners of already injected cias?

 

[hacksn5s4]

could you also make an easier way to import saves like the save injecteor for gba vc is not that good and its in python could you make a exe save injector for gba vc

@Asdolo So far the only trouble I'm having is getting games that need SRAM patched to save properly.

With the older tools like GBAFooterGenerator, it was possible to set Save Chip Manufacuter AND Save Type
and setting both correctly would allow games that have been SRAM patched to work properly. So you'd use GBATool to SRAM patch the rom, load it into footer generator as set Save Type to SRAM and Save Chip Manufacturer to EEPROM. (Weird I Know, but that's what you have to do to get it to work)

Then someone discovered there's some sort of blur toggle in that footer generator and now there's a footer generator that replaces Save Chip Manufacturer with Ghosting settings. Did nintendo put these two settings on the same byte or something? I'm very confused about this.

If there's anything I can do to help fix this, let me know.

For reference Asdolo, the easiest game you could use to figure this issue out is Super Mario Advance, it freezes saying "Save Data is Corrupt" on startup when it's not working. It needs to be SRAM patched by GBAtool to work and it seems like nothing I do in your injector, no combination of settings allows it to work, unfortunately. :/

With some experimentation and help from 3dbrew and hex editing I managed to create a footer for Super Mario Advance that removes the blur, is bright and colorful as it should be, AND works with the SRAM patch.

Hope this helps some with figuring out the footer stuff further
another good option would be allowing your own footer to be inserted but that's kind of dodging the issue.

Umm not to butt in but i did make a observation on this.

New version 1.2!

What's new:
+ Added: More rom compatibility (it fills with zeros the rom until it has a common size, i.e. 4MB, 8MB, etc). This may improve patched roms rompatibility.
+ Added: Now the random Title ID's won't match an eShop app Title ID.
* Changed: Now it generates a new Title ID every time you pick a gba rom.
* Fixed Issues with 32 bits OS (A.K.A. 'Could not find code.bin' error).


Links in the OP!

So, I have a pretty strange problem...
After creating and installing a few CIAs with your injector, NONE of my GBA CIAs (including those made with a different injector) work. They just give a black screen. I'm certain I haven't done anything to AGB_FIRM in the meantime that would have caused the issue.
