PSX - Piracy Warning on an ISO...any way around it?

[IT_Freely]

For the record, I honest to universe own the actual game, and am trying to emulate it on Recalbox as my PSOne AV cord is missing in the wind at the moment.

I am tying to get Dragon Ball Z - Ultimate Battle 22 working, but when it loads up flashes the piracy warning and quits back to the main menu. Not sure entirely but wondering if it might be a region issue. I do have the SCPH bios in the BIOS folder for PSX, but again, not sure what it might be here.

Is there a suggestion like a specific BIOS that allows multi region, some sort of boot disc, etc.?

My other rom for Dragon Ball Final Bout works (again own the actual title).

Appreciate any help.

Some PAL isos need sbi files.
