Explained the save game checksum routines in both Tony Hawk Pro Skater 2 (Japanese version) & Castrol Honda VTR (Japanese version) to help me create SuccessCheckSumUpdater (SuccessCU).

Berion of PSX-Place compressed the images of this document properly (this is the first time I’ve edited photos).
Martin Korth for confirming the SetSession bug found in VC0A, VC0B, and VC1A CDROM controller BIOS versions, and for the priceless PSX-SPX document.
Peppe90 of PSX-Place for testing NTSC gamems on a PAL PS2. His results have confirmed that the video mode can not be changed from PS1 software in PS1 mode on a PS1. It must be changed in PS1DRV from the PS2, as PS1 mode is set to always display the same video mode that the console shipped with (for the early PS2s that Tonyhax International supports). He mentioned that PS1VModeNeg v1.0.1 can be used to overcome this. The original Tonyhax issue explaining this also was helpful in figuring out how to bypass this PS2 level limitation.
