I used the EU version of the rom but i'm pretty confident that the US version would work just the same for what I did lol
Mini tutorial for what I did below bud:
Open up
gbata, then load in your rom and patch the SRAM so that it creates the "
output super puzzle fighter file"that you'll be using in the next part of the tutorial. T
hen open up the
3DS GBA Footer Generator and instead of keeping everything to default change
save type to
SRAM,FRAM (128kbit) and
save chip manufacturer to
0xC0 (SRAM <V112,FRAM,FLASH V131) then hit create and make the .cia like you normally would! That seemed to work for me and got me past the Capcom opening, I played the game and everything I choose Ryu and went some girl with a white head band and blue skirt, fyi not a fan of the series but I wanted to help you out since you went out of your way to help me thank you and let me know if it works for you k
Let me know if there's something you don't understand k bud
