| 9 | 9 | - Find real CRTC registers |
| 10 | 10 | - Some games doesn't set proper registers if you have interlace enabled, is there any real reason? |
| 11 | 11 | - Implement external ROM hook-up; |
| 12 | - Add remaining missing peripherals, SIO, HDD and w1300a network; |
| 12 | 13 | - FDC loading without the IPLPRO doesn't work at all, why? |
| 13 | 14 | - reverse / blanking tvram attributes; |
| 14 | | - there's a soft reset PCG init bug now (try for example Eiyuu Densetsu Saga then Excite Bike); |
| 15 | - there's a soft reset PCG init bug now (try for example Eiyuu Densetsu Saga then Excite Bike), MAME / MESS core bug? |
| 15 | 16 | - clean-ups! ^^' |
