v6502r

Visual6502 and VisualZ80 Remixed

WASM Version for 6502: https://floooh.github.io/visual6502remix/

...and for the Z80: https://floooh.github.io/visualz80remix/

TL;DR: Take the visual6502 project and turn it into a native+wasm app via perfect6502, Dear ImGui and Sokol.

How To Build:

Make sure python and cmake is in the path.

To get an idea about additional required tools, first run

> ./fips diag tools

To build and run the native version, run:

> ./fips build
...
> ./fips run v6502r
> ./fips run vz80r
> ./fips run v2a03r

Linux may require additional development packages for X11 and OpenGL development.

To build the WASM version:

> ./fips setup emscripten
> ./fips set config wasm-ninja-release
> ./fips build
> ./fips run v6502r
> ./fips run vz80r
> ./fips run v2a03r
