byuu says: Changelog: - SFC: "uint8 read(uint addr)" -> "uint8 read(uint addr, uint8 data)" - hiro: mHorizontalLayout::setGeometry() return value - hiro/GTK: ListView,TreeView::setFocused() does not grab focus of first item Notes: - nall/windows/utf8.hpp needs using uint = unsigned; at the top to compile - sfc/balanced, sfc/performance won't compile yet Seems Cx4 games broke a while back. Not from this WIP, either. I'll go back and find out what's wrong now.
