Fixed high mode RAM behaviour, it makes 177 to load proper "gameplay". It's weirdly a lot faster than it's supposed to be, dunno the reason so far ... I was actually trying to fix Arkanoid with this, but it still refuse to run ... if I remove timer irq it boots with gameplay issues ...
Wow, this is going back. I had a NEC-PC8801A as my first computer in like 81/82? Living in the US I don't even know how my dad got it, he worked at GTE about that time.. played a lot of Zork on it, laugh. The only graphic mode game was a Xevious knock off that I had to get from Japan through user groups and paper catalogs!
Fixed ALU bankswitch priority issues, makes A.E. to boot A game on which you shoots at ... mouse pointer formations. Seems very stupid as an idea, but game itself plays really hardcore-ish (I haven't even managed to finish level 1 after some plays). Might do a video of this once that I properly support ALU features:
Rewrote bankswitch model from scratch, now that I'm more confident with it. This will be also needed for supporting waitstate penalties at some point (some games are definitely too fast due of that). Result of this rewriting is Tobira wo Akete booting again ... and yes I know, rewrites are supposed to break the games, not fix them
