v0.3.2

Updated to show any error message at initialization using a message box in Windows.

heroed is a console application, and it requires passing the hero.rom file as a parameter when executing it. Because of this, it silently failed when running in Windows by double-clicking heroed.exe from the File Explorer. This update should prevent this.

Also, when running in Windows, SmartScreen will prevent heroed.exe from executing the first time. You must unblock it from the Properties panel, or allow it by click "Learn more" in the alert message, and then clicking the "Run anyway" button. This is because the exe file is not signed. If you don't trust the executable, you can also check the source and run from Python.

v0.3.0

Now you can set the initial and final screen of each level, so you can change the length of each level.
There are always 20 levels, so you must distribute all the 256 screens among them. All the screens of the same level are consecutive, from the initial to the final one.

v0.2.3

Minor fixes. This has been tested for editing some game screens, and it worked fine.

Linux and Windows executables included.
