‘The Goonies’ is a Konami 1986 original game for the MSX (1983) system. Using our custom compiler we were able to modify the game and add some enhancements.
Enhancements do not require modern technology
The game runs on the same hardware as the original game
The main enhancement is a complete replacement of the audio with music and sound effects played via samples. Music was taken from the movie sharing the same name.
music: ±6 minutes
sound effects/voice: ±2 minutes
The result of this project should be considered a technical challenge rather than an actual game that people would play. Samples and sound effects are mixed in realtime at 6khz on a 3.57mhz z80 cpu. The default sound chip in the MSX system is the AY-3-8910. Its a 3-voice programmable sound generator (PSG) designed by General Instrument in 1978.
