Need PS2 US patches for PS1 games Dino Crisis, Nagano 98, Tomb Raider4, and Crash Bandicoot2

[Babar]

Need patches for the following games. Dino Crisis (Was told that you don't need patch but copy just shows plastation symbol and freezes). Nagano 98 (Can't find a patch anywhere). Tomb raider Last Revelation (Not sure if it is #4 or what but the US patch for #4 shows an error when I try to patch it). Crash Bandicoot 2 ( No patch found anywhere). I have a Mod Chip in my PS2 from modchip. com and it seems to work for most games that I patch with PPFomatic and burn on CDRwin. Thanks for any help.
