Request : Xplorer FX NTSC-US rom (3.20)

Hello, I'm trying to flash my Xplorer FX to display on my NTSC-US TV. The only roms I could find are PAL so they don't show anything. Moreover I have not been able to communicate directly via the printer port. I can get X-Killer to communicate with my PSX via X-flash but I can't change the video mode of the Xplorer FX because X-killer talks to X-flash loaded rom and not the rom on the Xplorer FX itself.

Wayback machine does not help as the rom files are not archived.

Please help me.

Thank you.

Finally got it. With rom 4.52 you can change video mode from the menu.

For future reference :

1- Flash Xplorer FX with rom 4.52 from an X-flash CD
2- Restart PSX with Xplorer FX plugged in
3- With controller, press down 3 times and press X (should hear beeps telling your navigating menus)
4- Press down 4 times and press X
5- Press down 5 times and press X.

That's it, video mode should be changed.

Now I'd like to replace all cheats in the database for NTSC games. Anyone knows if it's possible to import a whole new database containing selected cheats?
