Thanks to the two games submitted by Charlie as not working (wheres the rest of you, eh? 😉 ), i’ve made a lot progress in fixing bugs in the CPU core… Critical Mass was particulary useful. Thanks for your help. Charlie! 🙂
As a result, the following games now seem to work perfectly… Arkanoid, Bubble Bobble, Critical Mass, MegaBucks (yay!) and Zynaps. The AI in Chaos is fixed, but there is still the odd graphical glitch. Starquake still seems to crash, which is a shame.
The bug fixes have also sorted out the flashing graphics in a few games, such as Spike in Transylvania. Now i’ve just got to track down that Starquake bug…
