So beautiful. 👍

This is literally the first time I've seen my own car in a video game. 😅

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

This nasty demon is the first boss in Black Castle 2.

#GameBoy #gbstudio #retrogames

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.

In Black Castle 2, you can reach higher areas via hidden platforms.

25%? Then it's very doable. A well-written ASM shmup with gameplay, music and everything else doesn't need more than 50%-60% of the CPU most of the time (even on the slower DMG). So there would be more than enough to work with.
