Thats PS2 "turbo" mode. I bet they disable the data cache in PS1 mode, or many many games will crash that dont expect the wonders of data cache. And "some programmers" dont even expect having to flush the instruction cache, when loading in a new segment .. do they ? (wink wink ;)

Maybe I'll try to find some tekken2 and run it on a PS2 myself one day.
