rolunaaaaaaaaaa

so I've been working on a fantasy computer emulator entirely just because I'm a nerd and I'm really really thinking about putting out a sort of little "come learn with me" sort of series on Patreon while I do it and then releasing the executables... I've been having a blast so far, it's so complicated but so cool

somebody make me get back to writing my next book

I’ve already given somebody a haircut (no I don’t know how) and made us breakfast and I’ve only been awake for a handful of hours PRODUCTIVE CAT

hi if you’re reading this you’ve just seen the most recent post in a long line of Ro learning how to build a retro computer emulator on a fantasy architecture she vaguely made up looking a lil like 6502 and she’s actively learning how to make the thing work. I will be crashing out occasionally. thanks for coming along on the journey lmaooooooo

I don’t know if I’m handling ROM right. I’m kinda treating it more like an initramfs and like loading it from ROM right into a RAM space? tbh that can be ok tho esp if I want to do something like the c64 did with letting the user write to the ROM range. which I’ll probably do to give the user more addressable RAM. the whole thing is unified bc why not so VRAM is addressable, ROM should be addressable, I’m still figuring out how to use the device range lmao probably just by programming peripherals in JS that then read and write to a specified range? that works right?

THE CPU FETCH DECODE DISPATCH LOOP WORKS ITS GREAT so that means the assembler is broken oh no

I’m gonna be better at assembly than ever before tho lmao

I somehow managed to give my assembler and CPU emulator completely different opcode tables how tired was i????
