Very nice progress, most classic arcade coversions work flawless (see attachents).
Found the reason of incompatibility with my TV: the core provides a composite (horizontal+verztical) 31kHz sync signal over VGA pin 13 instead of pure HSync. Discovered it accidentally, forgot to switch on my sync merger on my DIY RGB->YUV converter, and despite it the result was an acceptable picture (see screenshots). Probably it won't cause any visible difference on monitors being less picky than my TV.
Perhaps there's the same problem with the River Raid core, previously beta release (with red water) was compatible with my TV, the new one with corrected colours is not anymore.
I cannot test it the same way because of the component-incompatible vertical resolution of that core (1024 if I remember correctly). I would be very grateful if you would check that!
