Hacking GBA injection

[piratesephiroth]

Ah, yeah, now the jpgs look fine. Also no mdf header anymore.

The latest version can parse every alldata.psb.m I have, and all the sub-PSB files, and spits out the chunk data as separate files.

Minish Cap, converted to JSON. Just a tad larger.

$ ls -al alldata.*
-rw-r----- 1 andrew andrew 50434048 Oct 4 05:58 alldata.bin
-rw-r----- 1 andrew andrew 1014967149 Feb 23 03:16 alldata.json
-rw-r----- 1 andrew andrew 16252 Oct 4 05:58 alldata.psb.m
$ wc -l alldata.json
2657851 alldata.json

Disregard this, I went with the good old RAM dump method.

I must be doing something wrong. I've tried injecting FFV into Minish Cap and it keeps freezing my Wii U. any thoughts?

gba by nintendo isnt compatible with every gba game try another?

Thanks I figured it out. had a corrupted bin file.

I'm checking out the Compatibility List and it states that Final Fantasy I works with Mario VC, but it seems the injector won't work since it's 16 mb. is there a solution to this or should I inject via network?

You'll have to use ram injection for now.

Of the VCs I have, the one with the most space is Minish, but the FF1 rom is too large to fit.

Using The Legend of Zelda - The Minish Cap
Compressed file '1810 - Final Fantasy I & II - Dawn of Souls (E) (M5).gba' (11012286 bytes) too large for injection (max 7985152 bytes)

I have a mostly-working tool which lets me stuff in any size rom, but it's not ready for public consumption yet.
There is still something odd with the obfuscated 'names' table. I can write out a table which works, but for some reason I can't re-create the exact same table as the original.

No prob, take your time. Love your app. Thanks for you hard work.

That language is not approprate for this forum.

I just stumbled across this project based on asmodean's exm2lib, this makes things much easier.

PSB files are my bitch now.

Working:
Injecting smaller roms.
Injecting larger roms.
(E.g. FF 1 as mentioned by @buda81. I confirmed restore points work across a power-cycle.)

Not working yet:
Different size/type saves.
(E.g. SMA4 as mentioned by @piratesephiroth)
Time to start looking inside the sub psb's and the rpx.

time ./tools/unpack-psb.py -r "1810 - Final Fantasy I & II - Dawn of Souls (E) (M5).gba" -o z-minish/content.new/alldata.psb.m z-minish/content/alldata.psb.m

so you can now inject a 32mb rom?

SMA4 seems to work so far with:
1549 - Pokemon - Volume 2 (U) (Video).gba
2227 - 2 Games in 1 - Sonic Pinball Party + Sonic Battle (E) (M6).gba

Commit logs are your friends.

Commit logs are your friends.

i did read them but i didnt find anything sma4 related and since im not a very tech savy person unless you tell me if it supports sma4 i have no way to understand lol i just wanted to do some 32mb testing.

I've updated the README, just for you.

The biggest issue now is figuring out which roms work/fail with each VC game, which will mostly be down to save-game compatibility rather than the rom size.

There is a good description of the problem here:
