This page is all about the Super Nintendo version, it’s box, the game…. whatever I happen to know about it.
Written by SunSoft, I hacked this one to see how it worked and used it’s core method of using the 4 colour screen, as the basis of Lemmings 2.
The 4 colour character map screen was arranged in columns and DMA cleared, and uploaded to VRAM every game frame. This meant they could draw both the lemmings and explosions into this screen easily, giving them a solid basis for the game.
In Lemmings 2, I copied this method, but managed to speed up the rendering by storing the graphics in the first 64k, and pointing DirectPage (zeropage) to the base of the graphic. This shaved a good few cycles off each lemming, and added up over the 80 that I drew.
