I got Daigasso Band Brothers DX on my R4, I got the patched DS_MENU_.dat AND I got a 8mb .sav file. The game turns on. It works. I can play the Daily Concert, I can make my own song, and I can use the radio feature. But I can't play Single Player mode. It's the mode reached through Middle Option on the main menu > top middle option > Top option When I click on this, the game goes to a black screen and stays there, but the music continues playing. What is wrong? I have already tried formatting my SD card thanks to Chuckstudios on the IRC, but that didn't work. Another few questions: I can't use wifi if I'm playing on a flashcart, right? And these .sav files that I keep seeing with some of the downloaded songs, but...how do I use these? I downloaded on and it came with several different .bdx files (which I assume are songs). How do I actually use them? I have already used the search function, and I have not found any solutions to these. Also, I am sorry if this is the wrong board, I am somewhat new to the layout of the forum.
