Windows Mobile users have been enjoying smooth PS1 emulation for a while now, while Android users are stuck with PSX4DROID(v2) which is notoriously buggy, and whose developer charges for updates. Developer Schtruck has promised Android support for his rock-solid emulator in "a few days."
It comes after these videos hit YouTube a few days ago:
The emulator, which the developer has been working on for years has the tested support of 342 PS1 games, including multi-disc titles and numerous game pad overlays with (expected) bluetooth controller support.
PSX4DROID has desperately needed competition since it's launch on the Android Market. Seeing very few bug-fixes and compatibility updates, Android users have been avoiding it for years, all while Windows Mobile users have been quietly enjoying FPseCE on their HD2's and TG-01's.
