Hello, hoping this is the correct section. The situation is I purchased a Mayumi v2.1 to put into a PU-7 before I had the PU-7 motherboard. I blindly assumed it was in early release SCPH-1001 cases but the more I read it's only the Japanese SCPH-1000 consoles with S-Video correct? Or have any SCPH-1001's came with a PU-7?

I also had one more question. If the PU-7 is from Japanese consoles only is it possible to either swap bios chips with an English one or edit a dumped SCPH-1000 bios to add English text then flash that to a chip? Thanks!

Yes, the Japanese launch 1000 series had S-Video which were PU-7's, but only the Japanese models as far as I know.
Yes, you can swap the BIOS, but you'll also have to swap the HC05 if you do not install a modchip.
