Various fixes for Brandish 2
[src/mess/drivers]pc9801.c

trunk/src/mess/drivers/pc9801.c
r19456r19457
2929    - Dies on ARTIC check;
3030    - Presumably one ROM is undumped?
3131
32   floppy issues TODO (certain fail, even with a stock F version)
33   - Bokosuka Wars (perhaps not 2hd?)
32   floppy issues TODO (certain fail)
33   - Bokosuka Wars
3434   - Dokkin Minako Sensei (2dd image)
3535
3636   List of per-game TODO:
37   - 4D Boxing: tries to format User Disk;
37   - 4D Boxing: inputs are unresponsive
3838   - 4D Driving: accesses some undefined ports (guess that it accesses the low part of them with word opcodes ...)
39   - Absolutely Mahjong: Epson splash screen doesn't appear at all, why?
40   - Brandish 2: has some annoying strips at the main menu, also no selection seems to work;
39   - Absolutely Mahjong: Kanji data doesn't appear at the Epson logo. Transitions are too fast.
40   - Brandish 2: Intro needs some window masking effects;
4141   - Dragon Buster: missing bitplanes for the PCG, slight issue with window masking;
4242   - Far Side Moon: doesn't detect neither mouse nor sound board;
4343   - First Queen: has broken text display;
