7878    - Arquephos: needs extra sound board(s)?
7979    - Asoko no Koufuku: black screen with BGM, waits at 0x225f6;
8080    - Aura Battler Dumbine: upd7220: unimplemented FIGD, has layer clearance bugs on gameplay;
81    - Bakasuka Wars: drawing seems busted (either mouse or upd7220)
8281    - Band-Kun: (how to run this without installing?)
8382    - Battle Chess: wants some dip-switches to be on in DSW4, too slow during IA thinking?
8483   - Bishoujo Audition: Moans with a "(program) ended. remove the floppy disk and turn off the power."
r19818r19819
8685   - Bishoujo Shanshinkan: has white rectangles all over the place;
8786   - Bishoujo Tsuushin: hangs with a beep while writing some intro text;
8887
89    - Dragon Buster: slight issue with window masking;
88    - Dragon Buster: slight issue with window masking, that translates to abuse of the uPD7220 (sets resolution differently for each GDC);
9089    - Far Side Moon: doesn't detect sound board (tied to 0x00ec ports)
9190    - Jan Borg Suzume: gets stuck at a pic8259 read;
92    - Jump Hero: right status display isn't shown during gameplay (changes the mode dynamically?)
9391    - Lovely Horror: Doesn't show kanji, tries to read it thru the 0xa9 port;
9492    - Quarth: should do a split screen effect, it doesn't hence there are broken gfxs
95    - Quarth: uploads a PCG charset
93    - Quarth: PCG charset is wrong with normal display
9694    - Runner's High: wrong double height on the title screen;
9795   - Sorcerian, Twilight Zone 3: Fails initial booting, issue with 2dd irq?
9896    - Uchiyama Aki no Chou Bangai: keyboard irq is fussy (sometimes it doesn't register a key press);
