MEGA65 (XEMU) - Turrican Engine Demo
Notes from the dev:
"This prototype engine demo was built to experiment with the raster rewrite buffer and tools for importing 256 color chars, sprites and palettes from Aseprite. It's very much a WIP and has been discontinued indefinitely as I was unable to get copyright clearance. Please note it's mostly empty as far as functionality, just some basic controls, a single weapon type and a single enemy type, Turrican takes no damage and cannot die. While there are some hidden powerup boxes that can be uncovered and emptied, the powerups themselves cannot be collected."
