Prepare your original game files
Many Android ports distribute an engine or executable while expecting you to supply game data from a copy you own. Keep the original files private and do not upload them to a catalog or issue tracker.
Check the exact edition
Projects may support a particular retail revision, storefront release or regional version. Read its documentation before copying files. File names, checksums and formats are project-specific.
Prepare a working copy
- Install or extract your legally acquired game using the storefront or media’s supported method.
- Locate the files the port explicitly requests.
- Copy the required data to a separate folder, preserving spelling and directory structure.
- Transfer it to Android using your own USB, local storage or trusted transfer method.
- Choose the data folder in the port’s system file picker if instructed.
Let the project define the destination
Android storage permissions and app-specific folders differ by OS and application. Avoid assuming an old /sdcard path works on a new Android release. Follow the current project’s file-picker instructions.
Keep saves separate
Back up your saves before switching releases or data editions. Never replace an entire app-data folder without understanding which files are saves, settings and assets.
