I've got Japanese version of PS ROMS and found out some of them works really well, but few doesn't work on my x-box. If you could give me a tip that helps me playing those games don't work, I would appreciate it.
Also, I would like to share the info that helps everyone that are trying to play Japanese virsion of PS Roms.

By the way, to play Roms on X-box, I am using the SCPH1001.BIN bios for playing those from USA, but for Japanese virsion, I, just in case, am using the SCPH1000.BIN by changing its name to SCPH1001.BIN.

The lists listed below are Japanese virsion.

Games that works
Armored Core
Bomberman Fantasy Race
Dragon Ball Finalbout
Dragon Quest 4
DX The life 5
The Famiresu
Final Fantasy 6
Final Fantasy 2
Kyoufu Shinbun
Momotarou Dentetsu 7
Powerful Pro Yakyu 2002
Poppen Tanks
resident Evil 3
Silent Hill
Smash Court2
Street Fighter Zero 3
Tokimeki Memorial

Those that doesn't work....(Please let me know what's wrong...)
Metal Gear Solid..... Works on PCSX PS Emu on the PC... but doesn't work on X-Box..
Metal Slug.............. I can play first mission, but it freezes when starting second mission..
The Tetris............... Seems like when I am playing the game few min, the controller stop working...

If there is any problems for the Japanese virsion Roms, we can help each other.

We allready have a thread for this, link

just make sure to put (J) next to every gamename when you add them to the list.

Well, thanks for letting me know... I knew that there was the list.. I just wanted to make another list for japanese virsion.. I've checked the list, but it is kinda hard to find out Japanese virsion soft.. Just wanted to make it separated lists for both English and Japanese virsion... Well, but sorry anyway..

I found some that said PAL but no Japanese games, so you could be the first to add some Japanese games you tested.

also psx games are not roms, they are called iso's since its a cd image.

(eventhough iso means there's no cd track we mostly use the word Iso to describe cd images)

Got it working, (the dragon quest 4 remake iso i mean)

Use the 14th version core, with 116 and 19 plugin options, the menu now comes up and is workable. Not sure if this will work w the english 7 or not and I also had 2 dif bios in the bios folder, not sure which one it chose, 1001 or 1000. Someone pm and let me know how it turns out on the english 7 or if they need help on the japanese reprise.
