Reposted by undisbelieverNova @novasquirrel.com · 26/03/2026The Super Game Boy part of my Petal Crash GBC port ran into an obstacle since the original game uses screen shake effects that only apply to one board, and the normal SNES solution (mode 2) would've required giving up either the cool 12x12 blocks or the background. I found a cool creative solution. 25612
Reposted by undisbelieveregg boy color @eggboycolor.bsky.social · 02/06/2025Here's a Super Game Boy enhancement driver I need to finish some day.
