Haven't found a fix yet, but I've got it to a playable state. You can adjust the screen position from WITHIN the game menu. Just start a game then pause it by pressing "Start" then "Select". You should see "Screen Adjust" and just move it. (the opponent side will be partially cut off, but that's not important
)
As for the speed of the game....There's two way to slow it down. One is by the Option WITHIN the game and the other is to set "AutoSpeed=on" in FPSE.ini to limit 50fps max.
Also, the D-pad sensitivity seem to be a problem with fpsece 0.10.1 release. For example, if you press a button and hold for 1 second the emulator will process it as 2 second (exaggerated example).
