The enemy modifier codes don't work at all.
The Max Stats works for only Melee and Short.
Infinite HP causes graphical glitches and makes the enemy legs and right arm have infinite health.
(I know you don't make the codes, I'm just testing them so others don't find out the hard way)
I fear these are more of those kinds of codes that require the updated firmware of the official AR cart......unless the R4 team updates the AR compatibility, we're probably SOL for a lot of newer codes.
