Ecube Save Fix
What is it?
add link to GBA SAVE Patching guide.
This is a util to patch your homebrew GBA ROMs, to enable the Ecube client detect the correct save type. (If you don't know what I'm talking about maybe this guide will confuse you even more.)
Save Types
- SRAM - 256kb,512kb.
- FLASH - 512kb,1024kb.
- EEPROM - 64kb, 128kb.
Current Features
- “empty space” patch the ROM.
- Correct header information.
- Patch the ROM's Title.
- Patch the ROM's Game Code.
- Patch the ROM's Maker Code.
- Patch the ROM's Version Number.
- Pad the ROM to the next power of 2.
- Correct the CRC of the ROM after patching.
- Perform all operations through the commandline.
ToDo
HIGH
- IPS patching - it's the only things I can think of now I've done everything else I was originally planning
.
LOW
- currently nothing!!! Any suggestions?
DONE
- Optimise code and bring filesize down! (Well it's never really DONE).
- Add user input checking.
- “EMPTY SPACE” patching - looks for 12 bytes in the original ROM to patch rather than making ROM 12 bytes larger.1)
- Add CRC correction into my own program (to alleviate the need to use GBARM.EXE).
- Rewrote code from scratch.
- Add commndline handling.
- Fixed some memory management bugs (memory leaks
)

1)
Might cause problems depending on whether the “empty space” is actually used for something.
2)
These are in a seperate menu but the header fixing and CRC correction are done automatically when you use either of my save patching methods.
3)
From/Based on Darkfader's Gameboy Advance ROM fixer v1.03
4)
This is only in the source as yet. Nothing in the program does CRC stuff!
5)
The string and utils lib were from my “intro to programming” lecturer I should have credited him before. In any case Allistair McMonies. thank you for your string and utils libs. but I don't need them now!
