| 7 | 7 | a.k.a. same Jangou blitter but with NCS CPU for displaying graphics as protection. |

| 12 | 12 | TODO: |
| 13 | | -Night Gal Summer trips illegal opcodes on the NCS side, presumably a CPU bug; |
| 14 | | -Fix Sweet Gal/Sexy Gal gfxs if necessary (i.e. if the bugs aren't all caused by irq/nmi |
| 15 | | wrong firing); |
| 16 | | -Proper Z80<->MCU comms,many video problems because of that; |
| 17 | | -Abstract the video chip to a proper video file and get the name of that chip; |
| 18 | | -Minor graphic glitches in Royal Queen (cross hatch test, some little glitches during gameplay), |
| 19 | | presumably due of the unemulated wait states on the comms. |
| 20 | | |
| 21 | | Notes: |
| 22 | | -Night Gal Summer accesses the blitter in a weird fashion, perhaps it fails the ROM check |
| 23 | | due of address line encryption? |

| 38 | | 48 03 78 80 07 06 00 (again) |
| 13 | - Night Gal Summer trips illegal opcodes on the NCS side, needs to check if bit-rotted or encrypted ROM; |
| 14 | - Fix Sweet Gal/Sexy Gal gfxs if necessary (i.e. if the bugs aren't all caused by irq/nmi wrong firing); |
| 15 | - unemulated WAIT pin for Z80, MCU asserts it when accessing communication RAM |
| 16 | - Abstract the video chip to a proper video file and get the name of that chip; |
| 17 | - Minor graphic glitches in Royal Queen (cross hatch test, some little glitches during gameplay), |
| 18 | presumably due of the unemulated wait states on the comms. |
