NESFab is a new programming language for creating
NES games.
Designed with 8-bit limitations in mind, the language is more ergonomic to use than C, while also producing faster assembly code.
It’s easy to get started with, and has a useful set of libraries for making your first — or hundredth — NES game.
// This small program plays a sound effect.
// Variables:
vars /sound
UU pitch = 1000
// Sends 'pitch' variable to the APU, emitting sound:
fn play_sound()
{$4015}(%100)
{$4008}($FF)
{$400A}(pitch.a)
{$400B}(pitch.b & %111)
mode main()
{$2000}(%10000000)
while true
pitch *= 1.01

Performance
NESFab generates better 6502 machine code than any high-level compiler te
