{| border=2

The rest in pseudo-code:

for (int 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
}

* Someone please fix the code block's syntax, thank you :-)
