PS1: Do note that at least the US version is difficult to get running properly on emulator. The music tends to drop out, and load times may vary greatly compared to console. Console is highly preferred for US version runs.

Accepted emulators:
ePSXe 1.8
ePSXe 1.9
ePSXe 2.0 [Good]
BizHawk [Good]

Saturn: On the other hand, the Saturn version emulates much more reliably. SSF is a good choice of emulator.
