| 36 | 36 | - The Black Onyx: writes a katakana msg: "rino kata ha koko ni orimasen" then doesn't show up anything. (Needs user disk?) |
| 37 | 37 | - Campaign Ban Daisenryaku 2: Hangs at title screen? |
| 38 | 38 | - Can Can Bunny: bitmap artifacts on intro, could be either ALU or floppy issues; |
| 39 | | - Carrot: gfxs are messed up |
| 39 | - Carrot: gfxs are messed up during floppy loading |
| 40 | 40 | - Combat: mono gfx mode enabled, but I don't see any noticeable quirk? |
| 41 | 41 | - Fire Hawk: tries to r/w the opn ports (probably crashed due to floppy?) |
| 42 | 42 | - Grobda: palette is ugly (parent pc8801 only); |
