* blocks containing only 0xFF yield a checksum of 0x0F
* blocks containing only 0xFF yield a checksum of 0x0F
* blocks containing only 0x00 yield a checksum of 0xB9
* blocks containing only 0x00 yield a checksum of 0xB9
* possibly checksums apply to encrypted blocks?
* checksums seem to apply to encrypted blocks. In the case of Ridge Racer, all-zero 0x200 blocks yield 0xE4 instead of Rayman3D's 0xB9. However, all-FF blocks always yield 0x0F since they aren't encrypted.
This is most likely a custom checksum algorithm. Standard CRC8 would yield zero for a zero block.
