SSNES v0.4.1

SSNES is a simple frontend for the libsnes library. libsnes is the emulator core of bSNES, the most accurate SNES emulator to date, in library form. The libsnes API has been implemented by SNES9x as well, allowing multiple different cores to be used for an emulator that supports libsnes. This enables the possibility of custom front-ends for the emulator.

Changes since 0.4:

- XML cheat support. Supports cheats with same format as bSNES uses. (Mightymo's database). Badly needs on-screen fonts to scroll through cheats and stuff

This means that SSNES supports everything libsnes does, as far as I know (except for RAM monitoring, which is pretty much useless for SSNES' purpose I suppose).

- SDL video driver. Not recommended for modern OSes, but is reported to work quite well on legacy systems (Win9x).

- Forced 16-bit colors support. Can force 16-bit colors for OpenGL and SDL drivers (see legacy systems).

- Input handling in GUI is slightly improved for multiple controllers. The GUI is now more verbose on which joypad is used for which player.

- Added a new -D/--detach flag for Win32 users. Using this flag will disable the ugly DOS console window when launching SSNES from a launcher. (SSNES-Phoenix does this automatically.)

- Windowed scaling factor now respects the aspect ratio setting, rather than assuming a hardcoded 4:3 factor. (Width = aspect_ratio * scale_x * 224, Height = scale_y * 224).
