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 }
