PAL mode does not work, system locked to NTSC

[fanXbox]

I am happy with the new firmware version 2.1.10, which has solved many problems.
But I must point out that it is not possible to switch from NTSC mode to PAL mode (and with some games "Prince of Persia: Warrior Within" the localization does not work correctly), even if you do the switch several times with Enigmah and verify that the EEPROM is actually set in PAL mode.
I was able to set the PAL mode only by deleting the "kp.bin" file, but the video output is squeezed sideways, while if the monitor is set to "fit image", the image is shifted and enlarged.
