r19636r19637
8284    - Bakasuka Wars: drawing seems busted (either mouse or upd7220)
8385    - Band-Kun: (how to run this without installing?)
8486    - Battle Chess: wants some dip-switches to be on in DSW4, too slow during IA thinking?
87   - Bishoujo Audition: Moans with a "(program) ended. remove the floppy disk and turn off the poewr."
88   - Bishoujo Hunter ZX: Doesn't color cycle at intro (seems stuck?), doesn't clear text selection at new game screen;
89   - Bishoujo Shanshinkan: has white rectangles all over the place;
8590
8691    - Dragon Buster: slight issue with window masking;
8792    - Far Side Moon: doesn't detect sound board (tied to 0x00ec ports)
