Here's an update on how the retranslation is looking!
If you've played the game before, believe me when I say this is doing more to make it feel fresh than the colorization itself.
It still needs a final editing pass, but I'm really happy with how it's coming together.

There's a lot of confusion around the terms decomp, recomp, disassembly, and port, and people have been asking me which category Super Mario Land Advance falls into.
A small explanation here, in case you're interested: toruzz.com/unlisted/2026-10-…

After the disappointment w/ Pokémon I decided I wanted the fly to play something else, but this time for real, and only using the actual capabilities of a fruit fly brain.
And here it is: a fly playing Arkanoid on a Game Boy!
Read the thread to know more.

And big big thanks to Jonas Fischbach (@j0nas) for creating Retroid, which is this Game Boy version of Arkanoid I used.
Follow his work on the official website the-green-screen.com/
I wonder if it's possible to make the fly play Lunar Lancer too👀

(4) Am Stand von @retrospieler war u.a. der GAME BOY ebenfalls vertreten. Die Spiele sollten euch bekannt vorkommen, falls ihr auch im vergangenen Jahr auf der #Gamescom gewesen seid. Das Dottie Flowers für SNES werde ich mal im Auge behalten.

The legendary #Workboy found a new home!
I ported the ROM to work on the #MegaDuck laptop (a #GameBoy clone). Not the hardware we wanted, but.. hardware that exists! Keyboard, RealTime Clock, etc.
Free #DuckDuckWorkboy #rompatch on itch page:

Made a source-patch #MegaDuck port of the recent #Celeste Classic #GameBoy version by Rous/joshop.
Playable and fun even on blurry oem screens.

Made and shared with permission, only needed minor edits to get it running on the good duck.

Uncover a secret in "Black Castle 2". In the first level, just after the reaper, you can find a hidden heart.

I did an interview about Super Mario Land DX that didn’t end up being published as planned, so I’m sharing it here.
Hope you find it interesting!

I've hinted at it so much there's no point in keeping it under wraps any longer.
For the longest time, I've been working on a way to port GB games to the GBA.
What I ended up building is a modified GB>GBA emulator that targets a fantasy console instead - I call it the GB Bridge
Jonas Fischbach retweeted
OutRun never officially reached the Game Boy, but @EGVroom's 2025 homebrew OutRun GB delivers the full 1986 arcade original to Game Boy Color. Every track, every song, faithful visuals and handling - the portable version fans waited decades for.

Here's a fun little Sonic the Hedgehog visual demo running on Game Boy Color.💨
Fast and loads of parallax. Just a fun break from finishing up Starseed 3. !:)
