My R4 keeps screwwing up…need new formatt.. help?

ok so i hav this old R4 for NDSL & NDS and im tryin to play pokemon heartgold on it but it keeps glitching …im pretty sure its cause my r4 formatt is really old so it wont play

my friend had the same problem but she got her brother to put a formatt in called akmenu and the glitching stopped

im wondering if i should do the same
i heard there are other formatts like ysmenu and moonshell but they r for acekard…will work on r4?

if so where can i download these formatts and how do i put it on to the r4?
