* 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. | * checksums seem to apply to encrypted blocks.

This is most likely a custom checksum algorithm. Standard CRC8 would yield zero for a zero block. | <del>This is most likely a custom checksum algorithm.
