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! toruzz.com/interview/2026-01…

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

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. !:) #pixelart #indiedev #gameboy #retrogaming #Sonic #8bit #sega #screenshotSaturday

Retro console indie devs, it's that time again! Working on anything new for a retro console? Let me know! Drop me a line at marc@teamdebug.com if you're working on anything & they may feature in one or more of the UK print mags I work on. I may not be able to reply to you all.
