I fixed one for MMC5 and I also fixed the one for MMC3 as well when I notice the bug in The Guardian Legend. Here it is for most of them that look like this:

mmc3bankswitch:
php
asl
pha
lda #$86 ;might be another number for another game
sta $8000
pla
sta $8001
ora #$01
pha
lda #$87 ;might be another number for another game
sta $8000
pla
sta $8001
plp
rts


mmc5bankswitch:
php
asl
ora #$80
sta $5115
plp
rts


Thanks to FCEUX!
