Lo de los emus parece ser que de momento solo el de NES (fceu v2 ) lleva esa opción, aunque me aseguraron que el beta 4 de snes la llevaria pero no ha sido así , - aqui teneis las caracteristicas por si alguien no las sabia:
xSnes9x Beta 4
- Fixed memory leak which was causing Mario Kart, Lemmings 2 and selected other roms to lock on exit. Big thanks to The Joker for his assistance and advice.
- Added SDD-1 Rom support for Street Fighter Alpha 2 and Star Ocean. You'll need the Graphic's Packs from
http://www.dejap.com to run Street Fighter Alpha 2 and Star Ocean. Unpack the SFA2 graphics packs to the FreezeFile/SFA2SDD1 directory and Star Ocean graphics packs to FreezeFile/socnsdd1 direcotory.
- Added screen resizing and movement with both analog sticks while in game. Left Stick controls x,y movement, Right Stick controls stretching/scaling. Upon exiting a game your screen settings will be saved at the last set position.
- Proper NTSC/PAL/PAL60 support implemented.
- Fixed bug where some games would never create a valid SRAM save file. (Super Mario All Stars & World)
- Added Turbo Button - default is XBOX_WHITE . This is useful for speeding up intro scenes and large text passages in RPG's. The Turbo button can be mapped via the .ini file and is only active while the button is held down. Once a button is released default emulation will continue.
- Fixed a sorting bug with the rom list. For example if your list contained Mario.ZIP and Mario Kart.ZIP it would sometimes load the incorrect ROM.
- Added RomPath= in the .ini file where pathname is the directory to scan for ROMS. E.
RomPath=ROMS
RomPath=SnesRoms
etc
are valid paths. You cannot use absolute paths (RomPath=D:\ROMS is invalid)
The RomPath MUST exist as a subfolder under the main xSnes9x directory.
- Added *experimental* HDTV support. To enable this set one of 480p, 720p or 1080i to 1 in the .ini file. Since i have no way of testing this please provide feedback/screenshots of the output.
- DPAD Up and Down enabled in the rom list for more accurate selection."
