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.

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.
