			Sending the bad checksum response to the client will cause the client to overwrite portions of the character data. Specifically on PSOGC, according to chaos_ak, it clears such information as your inventory, bank, material usage, and C-Mode completion. Kayak (and Kabes) add that it clears techniques as well.

According to Fuzziqer's documentation, Packet 0x96 is some kind of client checksum. What it is a checksum of, I have no idea (but knowing about the checksums in PSOBB, its probably a CRC32 of something). Clients expect a reply to this packet that is of type 0x97.
