cleverest Posted December 18, 2016 Share Posted December 18, 2016 My Dreamcast games are all uncompressed in individual folders (GDI format, they have additional tracks files in the same folder), the US ones ONLY work...I have the file DC.zip in the roms folders where they are... I created a new instance in launchbox for Naomi 1/2 for Demul as I read was recommended, and tested Virtua Fighter 4 Final Run, it works fine...When I open a US DC game, it boots up fine too, but when I try a Japanese one, it only boots to the DC icon screen....the only difference I can make in the process is to choose VIDEO / VGA and some Japanese games tell me I have the wrong video mode selected...so I go back and choose RGB.... What am I missing, is there some special Japanese BIOS I don't have - where do I get it, does it need to be renamed and placed into the DC.zip? My setup, along with an example game not working...

DOS76 Posted December 18, 2016 Share Posted December 18, 2016 Yeah you are most likely missing the Japanese BIOS find a European game to test also as you may need to find that bios file too assuming you have interest in European exclusives.

cleverest Posted December 18, 2016 Author Share Posted December 18, 2016 I can't find anything besides various dc.zip packs online, and none seem to work :-( Quote Link to comment Share on other sites More sharing options...
cleverest Posted December 18, 2016 Author Share Posted December 18, 2016 I AM able to launch EURO PAL games (Ex Virtua Tennis 2 PAL), but for some reason the Japanese titles just won't work... ....anyone have these working fine with their DEMUL 0.7 builds?

DOS76 Posted December 18, 2016 Share Posted December 18, 2016 I have the Japanese version of Zero Gunner 2 running the first game I tried brought me to the DC menu which usually means the disc is bad Quote Link to comment Share on other sites More sharing options...
cleverest Posted December 18, 2016 Author Share Posted December 18, 2016 Hmmm I guess I need to test every one of these...and I'll let you know all know if any work. Thanks. Quote Link to comment Share on other sites More sharing options...
DOS76 Posted December 18, 2016 Share Posted December 18, 2016 According to this you should only need one BIOS for DC if using Demul. I'm guessing it could be the game the page has some pretty good info on Demul Quote Link to comment Share on other sites More sharing options...
cleverest Posted December 18, 2016 Author Share Posted December 18, 2016 This sucks, it's like 31 games, LOL, none are working if they are not US or PAL....darn... Quote Link to comment Share on other sites More sharing options...
