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:

Install Deno:

https://docs.deno.com/runtime/getting_started/installation/

You'll also need cmake and your system's C/C++ toolchain.

To get an idea about additional required tools, first run

> ./fibs diag tools

To build and run the native version, run:

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

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

To build the WASM version:

> ./fibs emsdk install
> ./fibs config emsc-ninja-release
> ./fibs build
> ./fibs run v6502r
> ./fibs run vz80r
> ./fibs run v2a03r

To develop the project in an IDE first run one of:

> ./fibs config win-vstudio-debug
> ./fibs config macos-xcode-debug
> ./fibs config win-vscode-debug
> ./fibs config macos-vscode-debug
> ./fibs config win-vscode-debug

...then open the project in Visual Studio, Xcode or VScode:

> ./fibs open
