I want to view the game data, I was stumped on their OBB (APK for Disney Getaway Blast) until I figured out its a ZIP with a custom header for likely the index (idx header) (I can open with 7Zip fine or repair using WinRAR), but many of the files in them, even the TEXTURES AND MODELS have this header of GCBF (Game/Gameloft/Code Binary Format/Framework?), along with the data in a funky format. https://we.tl/t-OEeYMs27KG
TGA/PNG: Usually a ZIP with split KTX'ed files
BDAE: ZIP with NFOs, a hash and the compressed BDAE.
SWF: ZIP with TGAs (SERIALIZED) and SWF.
GAME/LEVEL/TX(LEGO/GETAWAYBLAST/few in Tycoon), UI (Car Tycoon): JSON.
XLS/XLSX (All games)
UPDATE: Glitch isn't an engine, its a graphics api according to internal SDK mentions
