PSO Saves Trouble

Today I-ve created a new char *v1* in another VMU. I put a different Serial number/ key for the other.
I had both 2 VMUs inserted. Now I cant load any of them cause it says the file cannot be played.

I need to reset my DC bios to undo the serial input. I-ve done this long ago, not sure if it was with any browser cd, however I don-t remember anymore =( I tried using Pw2/ 3 and dreamkey, but no luck. I also searched on the net for Pw1, but coudn't find it.

I hope reseting the bios resolves my problem.
Any guess?

You have to use the same serials... now one of your characters has to be deleted lol. I suggest when you flash your Dreamcast you re-enter the serials for your old character and wipe the VMU file for the one you just created, then re-create him with the same serial. You can only flash your Dreamcast with PW 1.0, or with an unofficial memory flasher tool that you have to burn yourself. I think there's one in the pinned topics in Schtserv.

Also, moved.

Yeah, that's exactly what I thought! The problem is, where to find Pw1. Ok, let me check schtserv forum.

Edit: It has most of the browsers, but not the one I need unfortunatelly =(

Just flashed my DC.
No need to delete any chars yay
