| 18 | 18 | - Dust Box vol. 1-3: they die with text garbage, might be bad dumps; |
| 19 | 19 | - Dust Box vol. 4: window effect transition is bugged; |
| 20 | 20 | - Dust Box vol. n: three items returns "purple" text, presumably HW failures (DFJustin: joystick "digital", mouse "not installed", HDD "not installed"); |
| 21 | | - LayDock: hangs by reading the FDC status and expecting it to become 0x81; |
| 21 | - LayDock: hangs at title screen due of a PIT bug (timer irq dies for whatever reason); |
| 22 | 22 | - Moon Child: needs mixed 3+3bpp tvram supported, kludged for now (not a real test case); |
| 23 | 23 | - Moon Child: window masking doesn't mask bottom part of the screen? |
| 24 | 24 | - Moon Child: appears to be a network / system link game, obviously doesn't work with current MAME / MESS framework; |
