Alright I'm not going to take credit if its not due. Say as in.. I came last in figuring this out but. using the MHS money hack as a refference here. http://www.mpgh.net/forum/164-combat..._gp_-hack.html
I learned that if you set your "current value" for your EXP alongside "value when locked" to 1,500,000 the shop will think your an astrix rank and thus allow you to buy whatever the heck you want.
quite nice. I also palyed around to find that if set to 1,172,999
you can earn 7k GP after every game. and before anyone makes a smart comment like in the refference thread "its my choice to call it GP. call it whatever you want but i dont care what you think of my name for ingame money"
