Hi, I’m RuGrantez

But some people know me by my old handle Ruguevara.

I build tools for retrocomputing and demoscene—mostly in C++ and Python. I like making old hardware (ZX Spectrum preferably) do interesting things and giving myself and other people better tools to work with it.

Some things I’m building:

  • Dizher — perceptual image conversion for ZX Spectrum and Commodore 64.
  • µZX — a modern workspace for composing and playing chiptune music.
  • ZX-REAPER — agent-assisted game reverse engineering and porting, stage-checked against the original.
  • TAYM — interchange format for chiptune with timer fx.
  • PyAYay — sound-chip emulation bindings for Python.

I also contribute upstream to audio and demoscene tools, including Bitphase and Tracktion Engine.
