S1 (df422440) works with the uni-bios menu : check on emu-zone forum. Except that you have to register to get file attachments...and my chinese has gotten a bit rusty. So if anyone has this S1 or a link to it, please post. Patch to apply on s1 rom (7c7829aa) Muchos gracias, senor. I'm not spanish... Personally, I prefer debug bios to enable hidden charas. I know you're not spanish.
