  Run it in a browser in Wine on a MAC?

    None of them run in a browser powered by WebAssembly. I created a 2D engine in C++20 based on SDL, in which I can use Lua to create games. Then I thought, “I’ll make a NES emulator,” so I started with its CPU, the 6502.

      Have you run https://github.com/Klaus2m5/6502_65C02_functional_tests https://github.com/Klaus2m5/6502_65C02_functional_tests ? See also https://www.righto.com/2012/12/the-6502-overflow-flag-explained.html https://www.righto.com/2012/12/the-6502-overflow-flag-explai... I also note that you have the same code copy/pasted in every ALU operation which might be better expressed in one location for maintenance reasons.

        Good call out. Thank you! I will give a try.
