FPse PlayStation emulator debuts on the Android Market
Available for just under $5, and having dropped the CE (for Windows CE), FPse brings another PSOne emulation option to your Android smartphone. It's able to take ISO backups from your PSOne discs, something Sony's own PlayStation app for Android is very unlikely to let you do, and supports Android 2.2 and up.
So if you've been dying to get in on some Tony Hawk Pro Skater-action on the move, but haven't found other options to your liking, then check out FPse in the Android Market. Just make sure to have a look at the compatibility list before plunking down your hard-earned cash, just in case your favorite game isn't supported yet.
