SRAM/FRAM save type
There shouldn't be any problems with those.
FLASH save type
Save size less than 128kb:
Same as SRAM, it shouldn't cause any problems.
128kb saves, save type FLASH1M:
These are not supported by AGB_FIRM.
All games that use that kind of save will require patching to save properly.
Examples: all Pokémon games, Super Mario Advance 4.
Leaf Green/Fire Red and Ruby/Sapphire/Emerald require hex editing, as described
here or
here.
Other games (SMA4 and Pokémon Mystery Dungeon) can be fixed by patching their save type to SRAM.
Alternatively, you can use these IPS patches:
for all Pokémon games,
for Super Mario Advance 4.
Patching will change save size, dump save with Decrypt9 to check which exactly size game uses now.
If you want to inject 128kb save into patched game, you'll have to trim save first with
this app.
Just drag and drop your save onto .exe and type in the size that patched game uses.
EEPROM save type
512b saves:
Not supported by AGB_FIRM.
To fix saving you should patch games' save type to SRAM.
Again, this'll change save size and you will have to pad your save before injecting it into VC.
For padding you just have to add a bunch of zeroes or FF’s to the end of the save file,
you can use the same app as for trimming 128kb FLASH1M saves (read above),
just type in required bigger size.
8kb saves:
These EEPROM saves kind of supported by AGB_FIRM.
Such games will be able to save even without patching.
Yet you can't inject regular 8kb EEPROM save as is.
Here’s what you have to do:
1. Open your save with
Hex Workshop;
2. Then do: "Tools->Operations->Byte Flip"
3. Choose "Treat Data As: 64 Bit Unsigned Quad"
4. Press "OK" and save the file.
5. Rename save file and try to inject, it should work.
