Been great, just been chatting, sometimes even researching a Pokémon Black 2 ROM, last time I was experimenting with the sound data with the Wild Battle theme SSEQ, SBNK and SWAR files and transferred them over to the first Pokémon Black, tested them out... only to realize that most of the sound data had glitched up and only working when I encountered a wild Pokémon. Even then, it sounded very strange when the Pokémon was encountered and when the Pokémon was sent out, it stayed frozen there while the wild battle theme from Black 2 kept going. lol
I guess it isn't that easy as I thought it would be with exchanging the sound data from other NDS ROMs. xD
