During one of my wonders around the internet, i came across a video which claimed to be a Playstation One emulator for PocketPCs. I kind of dismissed it because I was busy. But I just check out the video and I'm amazed. It doesnt store the Rom on a large CF or SD card, it doesnt even involve remove bits from the orginal rom. No you use Wireless to transfer the rom bits needed. Wow!
Not tried it out yet, but going to try it someday soon…
