Control Warping with ASM Code (JP PM64)

%Exp points holds your group address, coins hold your room address. You can edit the exp points by holding L, then pressing dpad up or down to add/subtract. Holding R, then pressing dpad up or down will subtract from your coin count. Hold L + R while walking through a loading zone for the code to warp you to group (exp points value) and room (last byte of coins value) that has been specified. A + B + dpad up with 0 out the star points and coins, so you can always reset it back to 0 easily. Probably lots of optimizations to be made, may get around to it some time later.
