- Sound doesn't work in RidingF/RingRage?
(for RingRage it's probably a timing / cpu sync bug, if you go into test mode
for a while then exit you'll have sound, this doesn't work on RidingF)
- It does work in ringrage but you have to enter test mode first
\- It does work in ringrage but you have to enter test mode first
- Sound balance is not emulated (see arabianm test mode)
- When playing space invaders dx in original mode, t.t. with overlay, the
alpha blending effect is wrong (see Taito B version of game)
- Bubble Symphony has an alpha transition effect that doesn't appear in Mame
- Various other missing blending effects (see Mametesters)
- Find how this HW drives the CRTC, and convert video timings to use screen raw params;
Feel free to report any other issues to me.
