Not sure about this since when I was reading over the rules, i noticed that it said cronusmax and any adapter with programable-macros/mods/rapid-fire is banned. The normal cronus doesn’t have modpacks/rapidfire and is easily distinguishable from Cronusmax. (The plastic case says just Cronus instead of CronusMax.)
I want to know this as well. I use the standard cronus, it works flawlessly.
