byuu says:
Changelog:
- entire GBA core ported to auto function() -> return; syntax
- fixed GBA BLDY bug that was causing flickering in a few games
- replaced nall/config usage with nall/string/markup/node
- this merges all configuration files to a unified settings.bml file
- added "Ignore Manifests" option to the advanced setting tab
- this lets you keep a manifest.bml for an older version of higan; if
you want to do regression testing
Be sure to remap your controller/hotkey inputs, and for SNES, choose
"Gamepad" from "Controller Port 1" in the system menu. Otherwise you
won't get any input. No need to blow away your old config files, unless
you want to.
