Galaksija Emulator
Introduction
This is a Galaksija emulator for the SAM Coupé. It emulates the Yugoslavian Galaxy home computer, a Z80-based kit machine released in 1983.
The SAM version was ported from Tomaz Kac’s Sinclair Spectrum version, with the following changes:
- Mode 2 display, avoiding the mode 1 Spectrum compatibility slow-down.
- Stack based address look-ups to reduce drawing calculations.
- Frame difference drawing for massive speed-up.
- Frame rate limiter to stop the emulator running too fast (!).
- Compact matrix-based keyboard scanner.
- Disk loading of .gtp tape images.
- Miscellaneous optimisations.
Many thanks to Tomaz Kac for supplying source code, tape images, and technical help! Thanks also to Mark Boyd for his original display code wizardry.
