| More on the no-titlescreen version of Super Mario Bros and all hacks based on it. You can start the game properly on any(?) emulator by holding A when you press start. This is the hidden continue code which apparently bypasses the reliance on memory containing 0 at power-up. And the reason I read for this reliance is that the dump was modified for use on pirate hardware or something and didn't leave enough room to initialize memory properly. I've still found a few hacks that don't run on a proper emulator due to relying on inaccurate emulation of the sprite 0 hit and max sprites on a scanline flags (they freeze at the title screen or when you start the game). Graphics hacks are a common cause if they don't leave the all-important coin-sprite hit at the bottom of the status area. |
