Is anyone interested in helping port mame4all to OpenDingux? I've been poking around some to find starting points. I don't think the dingux version is really all that useful since it uses /dev/mem, /dev/jz, /dev/dsp etc directly. However, the gp2x port seems to use SDL so that might be where to start.
Also, SLDMame has been pulled into the main mame 146 sources. I think this would result in a much too large binary to be useful though.
