problems with bleem/other psx emulators, plz help!

[blade2002]

Hey guys,
I don't have a psx but some psx games, so I'd love to have a nice emulator for my pc (1.4 athlon, 265 ddr ram).
Unfortunately none of the emulators seem to work. When I run bleem (which seems to be the best emulator) it tells me an error (not a win32 application) and the crack doesn't work either (can't find bleem!.exe)

Can anybody help me finding a good emulator so I can enjoy tekken on my pc??
And what's wrong with bleem (the error even occurs in the demo version)??

Please help

tom
