Fix magic boosters conversion Fix small overflow error while converting magic boosters from right rotate to left rotate, in particular booster 38 was converted to 4122 instead of the corrcet value 26. Formula used was: s1 = original & 63, s2 = (original >> 6) & 63; new = (64 - s1) | ((64 - s2) << 6); Instead of: s1 = original & 63, s2 = (original >> 6) & 63; new = ((64 - s1) & 63) | (((64 - s2) & 63) << 6); This has no impact in number of cycles needed, but just in the resultig number that yields to a rotate amount bigger than 63. Spotted by Ehsan Rashid. No functional change.
