Actually you said you CAN'T emulate PSX games, you're just going back on that now.

You could just buy the PSX game, copy it as an ISO, then return it to the store, easy enough, plus there are plenty of torrent sites online that purely host torrents for game ISOs, including numerous PSX games.

Now if you'd started talking about how Saturn ISOs were hard to get, I'd agree with you, but certainly not for PSX games.

Anyway, get both, play Tales of Destiny when home, and Lunar Legend when away.
