So I have a build that runs pretty well in an emulator, but has serious rendering issues on real hardware. I'm still working to see if I can fix it tonight, but it is 10PM here so I'm starting to think this will go into tomorrow.

SORRY!

Fun Fact
The game contains an unused high-score table labeled MASTER MODE. Despite the name, completing the playable Master floor still counts toward the Expert rankings.

Advanced Extra Floor 5 is getting closer to 60FPS, and the Naomi to Dreamcast SDK continues to be useful.

Fun Fact
AiAi has a system for choosing what to look at. Nearby bananas and the goal hanging bag compete for his attention, with distance and direction affecting which target wins.

Just spent multiple days trying to pin down a character rendering issue that appeared while trying to improve performance. Luckily it has been fixed, and the normal work can resume. One positive side effect of this is that the physics should be much closer to the Naomi version in the next build compared to what I was originally going to release.

Fun Fact
The original arcade statistics save more than just scores. They include per-floor attempts, deaths, game overs, and continues, along with total, shortest, and longest play times.
