Important Notes:
Never remove the base game .pak file — the app won’t run without it.
Ensure patch files follow the correct naming and sequence.
Patch upload sequence matters — higher numbered patches override lower ones.
Best Practices
Upload base game first, then patches sequentially.
Always retain older patch files before overwriting.
Ensure correct naming:
e.g.,testPatch3-Windows_0_P.pak,testPatch3-Windows_1_P.pakRemoving a patch reverts the app to the previous version automatically.
Pre-made patch files:
