You have to remake the plugin and all using a modded file which you can find on a thread on here, but why would you want online plugins? As if we don't have tons of cheaters online already on every game out there...:/
For Battleminerz it's fine since it's a crap game overall that's only kinda fun for the first 30 mins until you realize that you've seen all there is to the game, so just look for the thread about online plugins on here or just use Luma's cheat function which works online (not 100% sure but it should). I'm just glad you aren't cheating on MH or Pokemon, TOO many online as is:/
