uo_Snes9x for PSP Ver.0.02y32 by y

Snes9x 1.43 is the base for this emulator.
This is an unofficial modified version of Snes9x based off of
Snes9x ver.0.02 for PSP written by Bifuteki.

{About Update}
Fixed minor corrections(received some reports).

{Caution}
Use the 333, 266MHz acceleration (standard is 222) option at your own risk.
I have set the emulator so that it will always run at 222MHz when return to PSP menu.

It is now certain that increasing the Graphic Speed will result in freezing and draw errors.
Depending on the game and the screen being displayed, Graphic Speed x1.1 will result in errors.
If problems occur please make sure that the GraphicSpeed and the SoundSpeed are set to x1.0.
GraphicSpeed and SoundSpeed settings are to be changed at your own risk.

Specific settings will be saved with each individual game.
I appologize, but any settings made to any releases of this emulator before y26
will be reformatted upon installation.
Please reconfigure to your desired settings.

I shall not be responsible for any incidents or disadvantages caused by the use of this program.
Please utilize this program on your own responsibility. 
You should read the license.txt.

{How to Install}
Place the {EBOOT.PBP} file in a folder marked {\PSP\GAME\SNES9X}.
Place the rom files wherever you wish.
Zip rom files are supported, but must only contain one file.
Access to SNES ROM images in *.smc, *.sfc, *.fig , format otherwise you will have nothing to run.
This emulator has only been confirmed to work with firmware Ver 1.00.

{About the Menu Wallpaper}
Place the {WALL.BMP} file in the same directory as this emulator.
The following format must be adhered to.
Using files that do not adhere to this format will result in display errors.
- 480x272x24bit Windows bmp format
- Header size 0x36byte (file size 391,734)
Creating the wallpaper with any standard application should result in an error free file.
Once installed the wallpaper can not be adjusted, so please choose a wallpaper
that is easyon the eyes.

{About Save Files}
In game SRAM save data (*.srm) is saved when you return to the PSP menu via the home key,
select a different rom, and put the PSP into sleep mode.  Therefore, if a game hangs before
you have a chance to do this the in game SRAM save data will not be saved.
You can manually save SRAM save data by selecting SRAM SAVE from the menu screen.

State save data (*.00?) is not compatible with the version before y21.
It is compatible with Snes9x.
The content of SRAM is included in each data.
Turning on the thumbnail save option will result in a compressed version
of the screen being saved. (*.tn?)

Menu settings will be saved everytime a game is played. (*_psp.cfg)

All save files will be automatically stored in the SAVE folder.
The default settings stored in the same folder as EBOOT.PBP. (uo_Snes9x.cfg)

Cheats date (*.cht) will be stored in the SAVE folder too.
It is compatible with Snes9x.
The input about description field is not supported.
When the file generated with Snes9x is copied, it becomes effective.
