Sad to hear Mark Volman has died. Always loved that era when Flo & Eddie were in the Mothers of Invention.

Happy #MaySiXth ! I haven't got my #MSX here at the moment, but these are some of the games I used to play as a kid, all purchased in the '80s.

Only 6 days to go until #MaySiXth, worldwide known as MSX-DAY! Everyone will post the best picture of their current #MSX setup so get cleaning, set-up the lighting, look for the perfect angle and make it a shot to be remembered!

This year there will be a free game too!

Asset extraction is coming along nicely. Managed to read the tilesets, spritesets and graphics data straight from the ROM file. Just need to apply the color palette.

In all my years playing this game, I never noticed that the big "Eggerland Mystery" title on the main screen is totally off center!

Streaming some #msx reverse engineering on Twitch. I'll be extracting graphics/assets from the Eggerland Mystery ROM.

NEW VID: an investigation into an interesting chunk of memory in Eggerland Mystery (MSX, 1985), where a little byte seems to be marching on.

Just released my first YouTube video, where I discover and delve deep into the two algorithms that handle how the level data in Eggerland Mystery is stored in the ROM cartridge.

Eggerland Mystery ROM patching is as good as done, can inject all regular and special rounds, as well as bonus stages, update the passwords and the special word. Simple download from the website where all rounds, 5-packs and ROM packs will be stored.

Sneak preview of the new Eggerland Mystery Online Construction Mode I've been working on. Made with PixiJS.

In the last few streams I have been reverse engineering Eggerland Mystery (#msx 1985), and figured out, among other things, how the level data is stored. I've been working on an online construction mode, a custom round database, and a blog post/YouTube vid to explain how it works. All released soon!
