Been on and off of this since November of 2024. It's an #animated revamp of the overworld from Super #Mario Land 2.

Prompted by the paint demo below, taking a lil detour to try hooking a #SNES Mouse directly up to #GameBoy (snes controller protocol over link port).

Commited a few crimes with the latch and clock polarity (signal inverter not here yet), but it still manages to ~work on a DMG.

We didn't share it in Bluesky back in the day, so today is the perfect moment to recall that a remastered colorized Donkey Kong is coming later this year.
