DirectInput RegKey

[Gismo]

Hi,

I'd like to modify the following XP's regkey:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Me diaProperties\PrivateProperties\DirectInput\VID_09 25&PID_8866

for using my PSXtoUSB adaptor as DirecInput and I found an .ini file in C:\WINDOWS\system32\DirectX\Dinput, the .ini that's attached, but I don't know what I have to modify.

The adaptor works as joystick in the following regkey:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Me diaProperties\PrivateProperties\Joystick\OEM\VID_0 925&PID_8866

Can anyone help me?

Thx, bye
