Here's a Super Game Boy enhancement driver I need to finish some day. It uses a circular buffer in VRAM to communicate with the SNES at 60fps via a combination of command data and per-frame data, rather than joypad packets. This particular version allowed a Game Boy game to reuse Game Boy Color art.

Hmm, never considered the Swedish word “handskar” (gloves), probably comes from “handskor” (hand shoes).

Just discovered this crazy joke #romhack the other day,
which lets you play SMB with #Mario at 16 times his normal size

"Mega Giant Mario Bros"
by "N-K"
it's the sequel to "Giant Mario Bros."

You can find the patch here:

ok so my quick project - which I'm now calling 'TrackPak' - takes a playlist of your tracker music and produces a music player GBA ROM for your album with album art and whatnot. It is actually getting close to MVP. I can probably finish it tonight/tomorrow

Our first big Christmas update is with an amazing recovery of the final build of Resident Evil on Gameboy Color. Hotgen's impressive conversion that got canned. This is much closer to completion, and seems completable too. Lots to discover!

Okay, here goes: what would *you* like to see in a retro "no-code/low-code" game creation tool? What tools/principles do you find helpful or interesting? I'm tempted to try making one of my own. (Assume WS/WSC for now, but don't constrain yourself!)

Cuebus preserved DoDonPuchi Zero (ドドンプチ零) and a trial version of DoDonPuchi (ドドンプチ)! Released in 2003, DoDonPuchi Zero was CAVE's first original shooter for keitai. Both were lost to time until now! DoDonPuchi Zero's soundtrack was composed by Namiki Manabu.
