PS2Recomp - How to get started recompiling (initial stages tutorial) YouTube video by Plastered Crab

Was looking for something new to do. Tried PlasteredCrab's PS2 Recomp tutorial www.youtube.com/watch?v=xCeB... and I managed to get to the end with just a bit of fuss! #ps2 #recomp

I probably overpaid for it, but today acquired an actual Sega Master System. #consolegoals #sega

I didn’t “like it” either, but I played the demo four times. So… maybe? But the girl’s hair is distracting and the constant talking annoys me.

This is totally not fitting my typical audience.

Another batch of comic strips. I can't help myself.

Yeah, it's random but I made some comic strips:

What boneheaded decision have they taken this time?

Working in a large code base is indeed like parable of the blind men and an elephant. You hope you've felt up the elephant enough to know what you're doing.

I listen to a fair bit of music when I work so when I go to a concert I always have the feeling I should bring my laptop. Otherwise I don’t feel as productive.

when the tools will get automated, things will get really crazy.

I'm like "I should do a decomp!" but the rate that everybody's going I think eventually whatever game I think of will be done in the next few years.

Current irrational thoughts: Hey! Let's reverse engineer Shadowgate for the NES and port it to everything!

Last article! Downland Unearthed Final: Porting The Game To Over A Dozen Platforms

Hi there! I don’t own the IP so unfortunately it’s a build-your-own affair where you’ll need an original Downland V1.1 rom.

Currently working on the final Downland Unearthed article, going through each of the ports I did. It’s gonna be a long one. #downland #tandy #coco

I want to see someone adapt Lord of the Rings where everybody’s in casual clothing holding a cup of tea or a small dog. Same plot points but just taking it easy.

Still don't know what kind of project to work on. Started looking at Cave Walker, the quasi-sequel to Downland. Started learning OS9's binary formats and using Ghidra to reverse engineer a small module. #tandy #coco #cavewalker #downland

Gonna invent a new console as a Mister FPGA core right quick. How hard could it be?

This guy Bresenham's like "I want my name to live forever. I'll invent a way to draw a line really fast"

Posted a new Downland Unearthed article, this time about background collisions.

Someone was selling a GBA flash cart near me. Picked it up and now I can confirm that Downland runs on hardware! #downland #tandy #coco #gba #gameboyadvance

These are still great. Arty print outs of Atari 2600 games' assembly code. I wish he still had prints for sale. I should've gotten the whole collection when I had the chance.

Seems like the OAM data for the title screen is pre-stored into memory at 0x600. Then copied on demand.

RE'ing Kung Fu, Day 8. Good amount of digging. The "background drawing" routine is actually a generic copy-data-to-ppu func. Figured out more about how its triggered. Explored how the snakes are shown on the main menu. Evidence of it being a general sprite draw func #nes #kungfu

If the length byte has bit 6 set then it’s a repeating tile.

So yeah. Backgrounds are made up of strips. Each strip has a screen location, data length, and the strip data. The data is copied straight to the PPU.
