Developer Vitor Vilela has once again used his knowledge of the SNES’s SA-1 expansion chip to improve SNES games, this time focusing on the game Gradius III. Previously, Vitor has focused on games like Super Mario World, but has also dedicated his time to help create dev tools and start SNESLab, a place dedicated to unifying the SNES hacking community.
In the simplest terms, Vitor’s SA-1 patching offloads some of the processing from the SNES’ CPU and PPU onto the SA-1 chip itself. This will allow original Super Nintendo and Super Famicom consoles to either run games it was previously unable to play, or remove slowdown from games that suffered when there was a lot of movement on the screen.
I have finally polished it and a now I consider the Gradius III – SA-1 version STABLE! Download sources and patch here: https://t.co/yNcIFniCdi
Video below is the infamous bubble stage that is extremely slow in the original game. Can you now beat it without lag? 😉🔥😈 pic.twitter.com/UaA6ZxYztz
