There's nothing else interesting besides fpsece on WinMo. The only reason to take the HD2 would be its actual price, and because it's possible it gets a port of WinPhone7. But if I tell you the truth, I would go for the Desire HD, or better, wait for that 2ghz monster Samsung is gonna release soon with Android Gingerbread on it.

On what device have you tried this crappy thing? lol On the HD2?
I've tried it on my HD2 with android on SD (then superRAM build), on my wife's Motorola Defy (with its omap overclocked to 1200Mhz...far from a Snapdragon but pretty good device) and could try it on the HTC DHD of one of my friends.
I'm using Android on my wonderful HD2. Thought I would see what psx4droid is like, its OK but not that good. It just made me laugh looking at the comments for psx4droid on the Android market, the latest ones are just asking about fpse release date. Lol.
Edit: After the one time I used the free version I've uninstalled it. It's nothing compared to what I'm used to with fpsece.
