Use this PocketSNES http://www.modaco.com/content/Smartphone-S...ators-for-C550/
I have Excalibur too and works very good, a little bit slow but playable.

And i have like 20 programs in cab files if you want some.

I have a Dash and most of the emulators posted here work. You need to make sure to install TGETFILE.dll on your system first (none of the emu's will run without it). Look for other posts mentioning this file, how to get it and install it.

I've tested the following on the Dash:

PocketNesterPlus 0.9 (aka NES) - Works great, full screen w/sound and smooth! (I only wish it had a volume control)

PicoDrive 0.52 (aka Sega Genesis) - Works great, full screen w/ sound (stereo!), some games play smooth (like Golden Axe), others are a little choppy (like Madden & Montana Football). Enable Fast Render. Try playing Ghouls & Ghosts, it's a mind blower...

PocketSNES 1.52 - A little slow, the screen isn't full and is a little hacked on the left (overlaps from the right), even in portrait mode. I never thought that SNES games ported well to a small devices anyway...

PocketEngine 1.0b1 (aka NEC PC Engine/TurboGrafx-16) - Doesn't work since it's designed for the IPAQ. Wishfull thinking, I know...
