There are literally no opcodes yet (though I've found a resource for then), I haven't implemented every graphics mode yet. Mode 3 graphics are doing just fine, and are what you're seeing here. Mode 4 also work :) How the heck does forkphorus run this like 6 times faster than Scratch https://forkphorus.github.io/#396344590
Site with original rom code: https://www.coranac.com/tonc/text/first.htm Image I used as reference: https://www.coranac.com/tonc/img/demo/first.png Great site with test roms and tutorials and stuff: https://www.coranac.com/tonc/text/toc.htm Change log: 5/17/2020, v0: Released without any instructions/CPU, tons of problems with the graphics mode 4, no graphic modes other than 3 and 4, but mode 3 looks good and I'm happy. I've gotten a few special memory locations programmed in as well and it makes me feel better about this for now :)
