SpecBong

Create-game tutorial for 8bit computer ZX Spectrum Next (modern-retro-machine) written in Z80 Assembly (Z80N precisely, using few extra instructions of ZX Next and using its extra features like 256 color gfx mode and HW sprites).

The resulting game can be played (on the real ZX Next or in emulator), although it's gameplay is very rudimentary, the tutorial ends in "half time" of game development, when all major systems of game work and game can be played and one should work on further content and polish.

Check the github page for full source code.

Follow the source code evolution through the text write-up, explaining the design choices and how the code works and how it was build up.

What you can learn in the tutorial:

• how to kick off Z80N assembly-only project, producing NEX file
• how to set up Layer 2 and HW sprites
• how to write simple game-loop code handling controls
• partial how to set up your PC for development

What will you need:

• basic knowledge about Z80/Z80N CPU instructions and assembly programming
• basic idea about ZX Next HW capabilities
