v1.0.0 — first release

First release of the native PC port of Tiny Toon Adventures: ACME All-Stars (Mega Drive, Konami 1994).

This download contains no game code. It contains the runtime (tinytoon.exe) and the tools that build the game from your own ROM: the recompiler, an embedded Python 3.12 and TinyCC. On first start (or during RecompLauncher's setup) the game is translated and compiled on your PC in about 20-30 seconds, and the recompiler checks that the result is byte for byte the code verified in development. See LEGAL.md for why it works this way.

What you need

Your own ROM of the European cartridge: GM T-95146-00, raw 1 MB .bin, CRC32 1227b2b2. Only that exact release works, since the code is translated from it.

How to play

Extract the zip anywhere and run tinytoon.exe. Pick your ROM once and it is remembered. Controls are in README.txt. With RecompLauncher, drop in your ROM and press Play.

What works

• The whole game, start to finish. Story mode and every stand-alone mode have been completed without a crash.
• Two players on one keyboard or with any two gamepads.
• Keyboard keys and gamepad buttons can be remapped in tinytoon.toml, or picked from ready-made layouts on RecompLauncher's game page.
• Stereo FM sound and the original 50 Hz PAL timing.
• Picture modes: pixel-exact, fill window and 4:3.
• Fullscreen, and quitting from the gamepad with L+R+Start.
• Mods: drop a .dll into mods/.

Known gaps (measured, not assumed)

Sprite masking, the VDP FIFO stall and YM2612 SSG-EG are not implemented. The game never uses them.

Third-party software in the zip

Python 3.12.10 (PSF), Capstone 5.0.7 (BSD), TinyCC 0.9.27 (LGPL 2.1, unmodified official binaries), SDL3 (zlib). The licenses are in LICENSES/.
