1414   - GRCG+
1515   - EGC
1616   - rewrite using slot devices
17   - some games put "Invalid command byte 05"
17   - some later SWs put "Invalid command byte 05" (Absolutely Mahjong on Epson logo)
18   - Basic games are mostly untested, but I think that upd7220 fails on those (Adventureland, Xevious)

1920    TODO (PC-9801RS):
2021    - extra features;
r19471r19472
3637
3738   floppy issues TODO (certain fail)
3839   - 46 Okunen Monogatari - The Shinkaron
40   - AD&D Champions of Krynn
3941   - Bokosuka Wars
4042   - Dokkin Minako Sensei (2dd image)
4143   - Jangou 2: floppy fails to load after the title screen;

4547   List of per-game TODO:
4648   - 4D Boxing: inputs are unresponsive
47   (A Midsummer ...)
49   - A Ressha de Ikou 2: missing text (PC-9801RS only);
4850   - Absolutely Mahjong: Kanji data doesn't appear at the Epson logo. Transitions are too fast.
51   - Agumix Selects!: needs GDC = 5 MHz, interlace doesn't apply there;
4952   - Brandish 2: Intro needs some window masking effects;
5053   - Dragon Buster: missing bitplanes for the PCG (or not?), slight issue with window masking;
5154   - Far Side Moon: doesn't detect sound board (tied to 0x00ec ports)
5255   - Jan Borg Suzume: gets stuck at a pic8259 read;
56   - Jump Hero: right status display isn't shown during gameplay (changes the mode dynamically?)
5357   - Lovely Horror: Doesn't show kanji, tries to read it thru the 0xa9 port;
5458   - Quarth: should do a split screen effect, it doesn't hence there are broken gfxs
5559   - Quarth: uploads a PCG charset
60   - Runner's High: wrong double height on the title screen;
5661   - Uchiyama Aki no Chou Bangai: keyboard irq is fussy (sometimes it doesn't register a key press);
