Old 8-bit binaries taken apart byte by byte and commented, with the tools to rebuild them: nothing gets claimed that the binary does not show, and the source has to give the original back, byte for byte. Right now that means 64 MSX games.
Games made from scratch, not taken apart: for the MSX, for the Game Gear, for a BBS and for the PC.
Battle Tetris for four on an MSX: four boards on one screen, and every line you clear sends garbage to the opponent you are aiming at; T-spins and combos send more. With the Ninja Tap four people play; if players are missing, the computer fills the gaps.
MSX with 16 KB of RAM · Ninja Tap optional
Tetris for the Game Gear, in colour: seven pieces with rotation and wall kick, a ghost piece, levels that speed up every 10 lines, and the Underwater theme from Alex Kidd in Miracle World. Playable from start to finish.
still to come: sound effects and high scores in SRAM
A simulator of the Spanish league: you run a club (tactics, line-ups, transfers, youth academy) and the computer plays the rest for 20 seasons, with the first and second divisions, the Copa, the Supercopa and the Champions League. Matches can be watched in a 2D viewer.
v0.1.0, the first release playable end to end · no team or player data distributed
