JerusalemLauncher

This launcher fixes the problem of being unable to save while playing Jerusalem on modern systems.

Usage

Place JerusalemLauncher.exe in the same folder of the game and use it to play, each time you go back to the main menu while playing a new save will be created.

How it works

The game actually has an autosave system: each time you access the main menu, it saves the current game on Data\Saves\SaveGame.ars, so this launcher creates a new save, named 1_ArSa#.ars (# is an autoincremented integer), in the same folder, when it happens.

The list of the saved games is located in Data\saves\user.aba and has this format:

• 4 bytes for the number of saved games;
• a list of saves in this format:
• • 4 bytes for the length of name shown on the load screen;
• • n bytes for name shown of the load screen;
• • 4 bytes for the length of the name shown on the load screen (again);
• • n bytes for the name shown on the load screen (again);
• • 4 bytes for the length of the save file without extension (1_ArSa#);
• • n bytes for the name of the save file without extension (1_ArSa#);
