PS1 NTSC-J Modchip

Hello Everybody,

I need your help to know if there is a modchip able to boot all on such a machine ?

In fact I recently purchase a MM3 thinking it will work the same as on my PAL unit.
But not, the Jap MM3 will only boot NTSC-J backup :-/

I have tested with my PS Hacker , all works but it's not the best, I would prefer a modchip.

Thanks for your help.

My PS1 is a SCPH-7500
Regards

 

There is no modchip that will allow it to boot all games.

Only way is to swap the bios

 

IRC scph 7500 doesen't have bios protection...
That's strange....

 

Any other test I could do then if 7500 should be OK (No Bios Protection) ???

Also, this would be a possibility then to swap bios ? Just a chip to swap ?

Thanks for quick reply !

 

First of all, the SCPH-7500 does indeed have territory protection in the boot ROM, and will only boot discs that have a Japanese license sector on them. All the Japanese PlayStations are like this apart from the early SCPH-1000 models.

Swapping the boot ROM works, with the best option being the SCPH-7501 or SCPH-9001 boot ROMs from the US consoles - they still boot in NTSC mode, but don't have any territory protection and have English menus.

You can also use a cheat cartridge flashed with Catela in conjunction with the modchip - this will allow you to boot copies or imports and still use the correct ToC from the disc you are booting.
