The title screen includes graphics for a less scantily clad fairy girl.

Also included is the text "VER-2".

Error Handler

Surprisingly, there is a fully functional error handler inside this simple game. Some parts of the game still have some debug asserts, which may call this handler, but in the final release, there are no such errors possible. Unfortunately, the graphics data for the font it's using is not in the ROM anymore, most likely due to lack of free space. The font loading routine is disabled, so you couldn't see the actual screen anyway.

After a restoration patch (add a standard 1-bit ASCII font to any location, enable the font loading routine by patching 0х001425-0хC9:0х00, then set the font offset at 0х001427, and finally set the test crash code with 0х001816-0хСD:0хC9), you may see a result like the picture above.
