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

[Deleted User]

So can you trim the GBA ROM before CIA generation?
Currently, you have to use the full ROM dump otherwise you cannot fetch the ROM info.

Does it need to use a custom firmware or can I do it without one?(

yes. cfw is needed to install the .cia files.

 

[Kruphix]

Ok. What custom firmware does it work with?

Is NSUI cancelled? It's been the same beta version for months and it doesn't even have a thread...

It's not. I'm working on it almost every day.

That's actually great to hear! I remember liking it, but a lot of features I wanted to use were either not there or broken in the beta, and I hadn't seen any discussion about it since a reddit post. Sorry to take you off topic!

If a trimmed ROM will run on a flashcart or emulator, it should be possible to inject it, too. You’d probably want to load the original ROM first and write down what save game settings are used.

I mean, I want the program to automatically trim the ROM before after determining info and before CIA generation.

The IPS patching does not work: I tried to use the IPS translation patch of FE6 but when I launch it in the 3DS it shows a white screen.
However, if I convert an already patched ROM, it works.
Also maybe you should consider more patching formats.

Try instead using NSUI beta 27 (https://gbatemp.net/threads/discussion-new-super-ultimate-injector-nsui.500376/) and let me know if it works.

Also, what patching formats do you want NSUI to support? Thank you.

How would you bring the games Save data? I.e. the save files and save states.

Suggestions:
1. When generating the CIA file, trim the ROM file first. Unlike NDS, GBA trimming is totally safe.
2. You should get the info from the ROM file's headers. Currently, if you try a patched or trimmed ROM file, it cannot fetch info. Patching or trimming may change some values in the header, but they should be still valid and they do not change the ROM's product code (which is to determine the icons, 3D banners and such).
3. Defaulting the 4-digit product code to the one of the GBA ROM's in step 4.
4. Do not restrict the font selection to TrueType fonts in the 3D banner.

hey, this is all so great! but for some games, this graphic problem happens ;_;
The lower part of the screen goes weird, and the upper part is cut off a bit.

Spoiler: the screen photos here

Do any of you know why this happens? I would be very happy if I knew how to fix this problem.

Here is a thread of people having this issue: https://gbatemp.net/threads/q-gba-cia-on-emunand-not-rendering-screen-correctly.397084/

It hasn't been figured out 100%, but it maybe seems to happen more often on SD cards that are 128 GB+. And cluster size is possibly a factor, formatting the SD using 64kb clusters solved it for some.

A more temporary solution is to repeatedly press the Home button, this can cycle the screen one line at a time or so until the issue is fixed for that session.

Thank you! I am kinda relived to know that it is not my own problem. Mashing home button didn't help me but when I turn off the game and then immediately turn on the game again, sometimes they work fine. I think this is the best temporary solution I can use right now...

Every time I play Pokemon Emerald the game doesn't load up and it shows a white screen what can I do?

Amazing tool, thanks! I actually have a NDS Lite, and was looking for a GBA Flashcard and recently tried the GBA VC from the 3DS. But i'm having some problems with three ROMs: Pokémon Emerald (U), Pokémon LeafGreen (U), and Klonoa Empire of Dreams (U)(Mode7). The program cant't find any data on the database for these ROMs. Its not like don't work, i use them on my smarphones and PC (Retroarch) Funny, Retroarch don't display any information about these ROMs. Should i try another ROM?

Also, Pokémon R/S/E had a RTC on original cartridges, do i have to check the RTC box on the program?
