Load WEP graphic from WEP1 Sheet Expects r4 = pointer to miscellaneous unit data (presumably for attacker). Expects r5 = WEP1 sprite data (lies within r4 table ^^) Expects r6 to be something important, saved to and loaded from stack at r29 + 0x28 r19 & r18 & r17 = r4, however r19 is overridden quickly by r5.
