Changelog:
- sfc/ppu-fast: added hires mode 7 option (doubles the sampling rate
of mode 7 pixels to reduce aliasing)
- sfc/ppu-fast: fixed mode 7 horizontal screen flip [hex_usr]
- bsnes: added capture screenshot function and path selection
- for now, it saves as BMP. I need a deflate implementation that
won't add an external dependency for PNG
- the output resolution is from the emulator: (256 or 512)x(240 or
480 minus overscan cropping if enabled)
- it captures the NEXT output frame, not the current one ... but
it may be wise to change this behavior
- it'd be a problem if the core were to exit and an image was
captured halfway through frame rendering
- bsnes: recovery state renamed to undo state
- bsnes: added manifest viewer tool
- bsnes: mention if game has been verified or not on the status bar
message at load time
- bsnes, nall: fixed a few missing function return values
[SuperMikeMan]
- bsnes: guard more strongly against failure to load games to avoid
crashes
- hiro, ruby: various fixes for macOS [Sintendo]
- hiro/Windows: paint on `WM_ERASEBKGND` to prevent status bar
flickering at startup
- icarus: SPC7110 heuristics fixes [hex_usr]
Errata:
- sfc/ppu-fast: remove debug hires mode7 force disable comment from
PPU::power()
[The `WM_ERASEBKGND` fix was already present in the 106r44 public
beta -Ed.]
