01 works the same as FF in this case, as long it's not null, but the bugs/fishes size values aren't modified, it's probably stored somewhere else
if you want to be sure that your game won't crash or bug, here is the "normal" code for a full encyclopedia :
Code:FE FF 12 EF 7F FD 7D 87 C1 38 80 A3 01 00 00 00 F0 FF FB FF 83 FF FF FF FF FF FF FF FF FF FF FF EF FF FF 29 D1 FF FF FF 7F 3F AF EF FF 7F 11 08 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 FC 5F F7 FD 85 AF FF 77 04 F0 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF BF 67 01 75 79 3E DD B8
Have you tried to inject that data into another player? Can he/she get the golden tools from contests after that?
Anyway... I uploaded a new tool: the item generator! It's basically a pocket/dresser editor through QR codes. Just put any items you need and it will generate a quick QR code:
