I believe for the n900 version they switched up the level orders a bit? 0067B4 01850500 [023] loadk 20 22 ; "Level23" 0067B8 41C50500 [024] loadk 21 23 ; "Level44" 0067BC 81050600 [025] loadk 22 24 ; "Level52" 0067C0 C1450600 [026] loadk 23 25 ; "Level34" 0067C4 01860600 [027] loadk 24 26 ; "Level42" 0067C8 41C60600 [028] loadk 25 27 ; "Level24" 0067CC 81060700 [029] loadk 26 28 ; "Level88" 0067D0 C1460700 [030] loadk 27 29 ; "Level36" 0067D4 01870700 [031] loadk 28 30 ; "Level31" 0067D8 41C70700 [032] loadk 29 31 ; "Level21" 0067DC 81070800 [033] loadk 30 32 ; "Level41" 0067E0 C1470800 [034] loadk 31 33 ; "Level76" 0067E4 01880800 [035] loadk 32 34 ; "Level38" 0067E8 41C80800 [036] loadk 33 35 ; "Level35" 0067EC 81080900 [037] loadk 34 36 ; "Level20" 0067F0 C1480900 [038] loadk 35 37 ; "Level26" 0067F4 01890900 [039] loadk 36 38 ; "Level66" 0067F8 41C90900 [040] loadk 37 39 ; "Level85" 0067FC 81090A00 [041] loadk 38 40 ; "Level27" 006800 C1490A00 [042] loadk 39 41 ; "Level32" 006804 018A0A00 [043] loadk 40 42 ; "Level72" Also, I suppose I should mention that if you don't want to destroy your Angrybirds original levels you can simply copy your Level1.lua as every single one of those file names and then add them to another directory called pack2 or pack3. (hell if I know which) They'll appear in the menu as if they were the expansion levels and you won't have to trash your original ones, just make sure to edit whichever level files correlate with the second and third stages.
