make a 1:1 copy using cdrwin, applying the
ntsc->pal (or vise versa) if neeeded. go to megagames.com in the "psx utilities" section, download the action replay game shark cd
burn it to a cd-r using cdrwin

then go to code edit & enter these codes
D002D51C 023A
8002D51E 1000
D002D494 000A
8002D496 1000


after that, load the game. and it should work.

it worked on the ntsc version for me. i just made a 1:1 copy using cdrwin, booted up the gs cd, entered the codes, and then loaded the crash bash game. and it worked fine for me.

i'm not sure if you even need to apply the pal/ntsc patches when using the gs cd.. i've never tried playing an import game.. so that could be the only way that it might not work. but its damn well worth a shot. at worst it will cost you 2 cd-r's, at best it will cost you 1 cdr and you have a working copy of the game.
