Its like this for most flashcarts:
Get newwest firmware.
If game fails to run on newwest firmware you can TRY arm7 patching.
If this also fails you will be waiting for a firmware updage from your flashcart company.
(Myself I use the DSTT I was gonna play some patched JUS but ended up with 2 white screens)
(I arm7 patched the game and it ran like a charm)(DSTT do is updates so that proofs arm7 fix also is needed for some games even if the company still updates)
(Think I also needed a arm7 fix on guitar hero after apply-ing the no grip patch)(I cant remember what firmware I used back then but arm7 fix again made it work)
(I think these 2 are the only 2 games I ever had to arm7 patch.)
