I was just thinking today, that a Dreamcast Emulator would be awesome on the PSP. Imagine Sonic Adventure, Powerstone, Soul Calibur, Code Veronica + many more.
It might be a dream, but do you think the PSP has the horsepower to pull it off? Sony are releasing a PSOne emulator, and the PSOne wasn't as powerful as the Dreamcast, but the PSP supposed to be not far off the PS2 for power. (Sort of a PS 1.5). We don't even have a working N64 Emulator yet, but i think the Dreamcast would be the holygrail, i just can't ever see it happening. You can't even get a good Dreamcast emulator for the PC can you?
