Dumping GBA carts with null title and developer codes

[ploiu]

Some after market Gameboy advance cartridges (like shantae advance: risky revolution) don't have the game title nor the developer code populated in the ROM header. Does this make it impossible for the cart reader to detect automatically?

If I add an entry for that game in the gba db file, it doesn't seem to be recognized until after the CRC32 is calculated

I have updated the code to read a nulled out game ID as "0000" instead of "" and re-ordered the database by game ID so entries with the same game ID are grouped together.

To create a database entry for e.g. Risky Revolution you just use:
name
crc32,0000,size,savetyp
If there a multiple entries with 0000 as game ID you can use the rotary encoder to select between them.

Risky Revolution does have the string "RISKY REVOLUTION" at offset 0x65A05. So we could also hard code the detection.

Oh awesome thank you! I was definitely looking at the wrong address for the title then, thanks for pointing that out as well
