Started to write a driver for Cycle Mahbou, an obscure game from Taito / Seta. It seems to be the logical next revision of the Joshi Volleyball / Great Swordsman HW, and like them, it has 2 Taito 8741 MCUs to care about…so it’s not yet working mainly due of that:

This game was brought to you by Chack’n from Team Japump & Dumping Union, a present gift for the Christmas 😉

Today I’ve beated color prom decoding in two games, first one is Carrera…

…and the second one is Super Moto / Super Rider:

Both of them uses awkward prom encoding and required a decent effort from my side to finally get them right. Amusingly, I’ve got the Super Moto one by seeing that it requires a very specific pen color for the ranking screen that was entirely black, fixing the bitplane order by checking that specific screen was an obvious choice for it.

I’ve also tried to fix Koi Koi Part 2 colors, but current dump looks incomplete (the prom is only a look-up one, the proper color prom is undumped apparently)

Fixed colors and some video glitches in Kusayakyuu

…and apparently this game looks a prototype / location test release? There are many apparent BTANBs in there, namely:

*I’ve did 1 run and the game gave me two points

*When the player slides there’s a small video flipping bug that cannot be fixed because it clearly breaks other stuff;

*It gives just five seconds on the team selection screen

EDIT: Added proper sound:
