Hi! Thanks for the fast reply. I tried reformatting and it didn't work, nor did the Woods firmware. I don't know if it's relevant, but it works on the 1.4 DSi firmware.
EDIT: Managed to get the 3ds to detect it by updating the kernel of the flashcart and now works with the R4i GOLD launcher...
Hi everybody! I've tried all of the launchers attached to the main post and I can't seem to be able to boot into my flashcart, which is an R4i SDHC 'Brand New' V2.0 (r4isdhc.com).
On the back of it 'R4i SDHC 9' is written.
What should I do? Is there any other firmware that'll make it boot...
@Xdqwerty, Osu! Tatakae! Ouendan! is the Japanese version of the game, different settings/characters/songs but otherwise identical mechanics. I played that before I knew about Elite Beat Agents lol. Both fantastic games https://en.wikipedia.org/wiki/Osu!_Tatakae!_Ouendan
