Hello ! If you change the bios by a Dreamshell Bios without change the language before,you can't change the language after because you need to go in the SEGA Bios for change Language. Of course,if you reflash in SEGA Bios for change..it works but I would like to find an easy solution when you forgot to change the language ! I contacted "Japanese_Cake",but he is very busy. He told me for a DEV (I am not a dev...) it's very easy to create an App for that. So I hope to find help with one of you to create this application under Dreamshell ! Thank you in advance !
