The Terra Cresta Amiga Adaptor is an innovative solution that enables fans to experience the legendary shoot-’em-up Terra Cresta on their Amiga 1200 and Commodore CD32.
Designed for enthusiasts who own a set of original Terra Cresta arcade ROMs, the adaptor delivers a seamless way to enjoy the iconic arcade classic on original Amiga hardware.

On the first run of the game a Z80/Yamaha OPL emulator renders all the sound effects and saves them on disk. Then the graphics are converted and the original game code is run on the Amiga, leading to a 100% accurate representation of the game, not an emulation!

• Trainer with 15 different options
• Pixel-accurate graphics and gameplay
• Original sound effects (programmatic and sampled)
• Load and save high scores
• Supports joysticks and CD32 gamepad
