Need help with Um Jammer Lammy

[Buron]

Hi. I have the US/NTSC version of the psx game Um Jammer Lammy. It has an anti-mod protection that locks the game when the stage is loading.

I have been searching for a patch on the net, but all that i can find are patches for PAL or japanese versions. The only one for US/NTSC is a PAL/NTSC selector wich doesnt remove the anti-mod protection.

I would like to know if theres someone who was able to find this patch. If not, anyone could say me how to remove the anti-mod protection by myself? (creating a patch or something like that...).

Thank you.
