ROM Data Compression

arefu edited this page Oct 5, 2023 · 1 revision

This game uses JCALG1 (Thanks Wisk & Alex O). The library and more information can be also found on Jeremy Collake's GitHub, apparently Jeffery Lim or Adam Leggett have connections.

This is based on previous research done by various members on the RomHacking forum https://www.romhacking.net/forum/index.php?topic=36943.0

Also, when attempting to read certain data in the rom it appears that code at 0x03000000 starts unpacking with JCALG.

However, I am yet to work out what handles the sprites, let alone sound but I suspect much of it is compressed the same way.
