OK, I know first hand that this works on Samsung Galaxy S7 (without tab) and S20, Android 8 to 11. So I am quite confident we will bring this to work. And the presplash.png never shows on Android, it's a Windows only thing.
- First, please make absolutly sure that you downloaded the most recent and official versions of both game and mod.
- Make a backup of your saves and the persistent file.
- Go to Android settings for Summertime Saga and delete both cache and data.
- Uninstall Summertime Saga.
- Re-boot your tab.
- Install Summertime Saga. Install only the game, no mods, no translations no nothing else.
- Run the game and verify it works. Play through the first day (first time visit Erik, School, Eve, Diane, gardening minigame, overhear Diane's phone call etc.). Go to sleep. Make a save at this point in his room after MC woke up and finished dressing. Go to the main town map directly (using the map icon) and make another save there. Leave the game.
- Now install the mod. Follow the instructions carefully, to the letter. Install nothing else.
- Run the game. Verify that the "Naughty Tribute Mod version ..." line is visible in the bottom of the main menu.
- Load your save. A warning may appear that it could not be loaded normally, dismiss that. You may solve that later with the LOAD_ERRORHANDLING parameter.
See if you can play now. If yes, report back here, please. If not, go to settings and disable the mod with the DISABLE_MOD parameter, try again. This disables the mod as if it was not installed and should work, but, certainly, without mod features. Report back here the results.
