The popular mobile Playstation emulator FpseCE is now available for Google Android. Appropriately, the developer has dropped the CE (which stood for Windows Compact Edition) from the name, and you can now download FPse from the Android Market for just under $5.
Sony is actually expected to launch its own PlayStation app for Android soon, making classic PlayStation One games available for purchase. The advantage of using a third party emulator such as FPse or psx4droid is that you can rip your own CDs to play most PSOne game (or download games off the internet… for titles you already legally own, of course).
FPse for Android also supports Android 2.2 and up, while the Sony app will require Google Android 2.3.
Some early users are reporting bugs in the FPse forum, but developer seems to be actively working to improve performance.

I doubt Sony will allow that and complain to the Android market staff.
