SD Gundam G Generation Over World - NPJH50681

[korgano]

BGM and Voice work fine in rev 2810.
Anyone know how to set the custom bgm in JPCSP? You supposed put the music file in /MUSIC/OVERWORLD/ directory in your storage card.
But I dont know where to put it in JPCSP folder ==a

I stuck it in the ms0/PSP/GAME/Music/Overworld directory (since that's where the memory stick stuff is), but it doesn't seem to work for some reason.
