I'm more of a fan of the Japanese version of Bakugan than the english version. I also like the Japanese voices better anyways. I was waiting for the Japanese release of the game, and now it's finally here.
How to play "Bakugan Battle Brawlers DS: Defenders of the Core" on your DSTT and R4
For DSTT User:
Copy the TTMENU.DAT files from the DSTT kernel to the root directory of your DSTT. And also, copy three files of infolib.dat, extinfo.dat, and ttpatch.dat from the DSTT kernel to the TTMENU folder of your DSTT.
Use YSMENU with the same manner of the above instruction as like DSTT. Thus, use R4 YSMENU. You must use the r4patch.dat file that was included in this karnel, and copy it to the TTMENU folder of your DSTT.
Note: The file of extinfo.dat can record up to 512 game titles. If the entry exceeds 512 game titles, the extinfo.dat can not be recognized by DSTT kernel. Therefore the special patch was applied to the three files of TTMENU.dat, r4patch.dat, and ttpatch.dat files. You must use these files together after this.
