Galaksija Emulator

Introduction

Galemu 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
• Framerate 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.
