Very nice indeed, it's really amazing seeing this stuff running on the Z. So far I've tried Wipeout 2097, Castlevania, and Oddworld, unfortunately none work at a real playable speed, and there are some emulation glitches but nonetheless, very nice.
I notice in
this thread you mention installing an sdl bvdd ipk, but I've not been able to find one for pdaxrom, maybe this is only for qtopia, but if there is such a thing that could accellerate psx4all on the CX000 series, would be nice to know.
Just a suggestion but how about including some frameskipping mode (if there isn't already) to maybe speed up the emulation at the cost of looks, I see no evidence of such a mode in the menu.
Great work, I hope life goes on with this project
