A programming language that compiles down to 6502 NES assembler
npm i -g nesly
Take a look at the mario-demo.js
file. There is a lot of stuff hardcoded in asm to get the example working. It's not really ready to use for creating anything useful.
To get the example running you need nesasm and a nes emulator.
nesly mario-demo.js mario-test.s;
nesasm mario-test.s;
open mario-test.nes;
