In higan, you can crop however many lines you like from the top or bottom of the image. But for bsnes, it automatically eats sixteen lines. My view right now is that if bsnes is meant to be the casual gaming emulator, that it should eat line 224 in this mode. Most games show content here, but because of the way the SNES PPU works, the very last line ends up on its very own tile row (line 0 isn't rendered), if the scroll registers don't account for it. There's a small number of games that will draw junk data to the very last scanline of the frame as a result of this. So I chose, at least for now, to hide it. Users can obviously disable overscan cropping to see this scanline. I'm open to being convinced not to do this, if someone has a compelling reason. We're pretty much screwed one way or the other with no overscan masking. If we output 239 lines, then most games will render 7 blank lines + 224 drawn lines + 8 blank lines, and the black top and bottom aren't centered. But if we output 240 lines to get 8 + 224 + 8, then games that do use overscan will have a blank line at the very bottom of the window. I'm also trying out a modified cheat code file format. It's been forever since I bothered to look at it, and the “cartridge” parent node doesn't match what I'm doing with trying to rename “cartridge” to “game” in manifests. And indeed, the idea of requiring a root node is rather superfluous for a cheat code file. Current format looks like this: cheat description: foo code: 7e2000=20+7e2001=30?40 enabled cheat description: bar code: 7e4000=80 Open to discussing this, and I'd like to sync up with Snes9X before they push out a new release, and I'll agree to finalize and never change this format again. I chose to use .cht for the extension when using game files (eg gamename.cht) |

The unofficial higan repository
higan emulates a number of classic video-game consoles of the 1980s and 1990s, allowing you to play classic games on a modern general-purpose computer.
This repository includes the source-code for stable and WIP releases of higan, starting during the development of v068. It also includes community-maintained documentation.
Basically,
apart from .gitignore
files,
anything in the
higan,
hiro,
icarus,
libco,
nall,
ruby,
or shaders
directories should be exactly as it appeared in official releases.
Everything else has been added for various reasons.
