The rest in pseudo-code:
for (i = 0; i < amt_of_items; i++) { item_amount = read_u_byte(); // Item Amount: U Byte
if (item_amount == 255) item_amount = read_int_me_b(); // Item Amount (if entered as 255 previously - to allow bigger amounts than 254): Integer Middle-Endian Big (Inverse middle)
item_id = read_u_short_le_a(); // Item ID: U Short Little Endian Special A }
