Tim Allen 3a9c7c6843 Update to v099r09 release.
byuu says:

Changelog:
- Emulator::Interface::Medium::bootable removed
- Emulator::Interface::load(bool required) argument removed
  [File::Required makes no sense on a folder]
- Super Famicom.sys now has user-configurable properties (CPU,PPU1,PPU2
  version; PPU1 VRAM size, Region override)
- old nall/property removed completely
- volatile flags supported on coprocessor RAM files now (still not in
  icarus, though)
- (hopefully) fixed SNES Multitap support (needs testing)
- fixed an OAM tiledata range clipping limit in 128KiB VRAM mode (doesn't
  fix Yoshi's Island, sadly)
- (hopefully, again) fixed the input polling bug hex_usr reported
- re-added dialog box for when File::Required files are missing
  - really cool: if you're missing a boot ROM, BIOS ROM, or IPL ROM,
    it warns you immediately
  - you don't have to select a game before seeing the error message
    anymore
- fixed cheats.bml load/save location
