hello dear people!

i am having a problem with my emulator,
it seems that it doesn't play my original copy of Resident evil 1 nor any rom that i can find.
while other games work fine..

i also tried to make a master image of the disc, but also doesn't seem to work.. (input/output error)(?)
anyone familiar with this? since i just have the itch to play this nostalgic game again!

i am using a macbook pro 2009
running OSX and my emulator is PCSX (PCSX-Reloaded (1.9.92)
i have working bios files..

Thank you!
