Check all three key bindings dialogues. One of the others must be set to use LShift. Glad it is all working for you.
Thank you very much ZoriaRPG!
Zelda classic is now able to fit on my screen properly, including the menus. Zelda Classic also doesn't freeze on my computer anymore! It still gives me the "all key bindings must be unique" message when I try to set the start button to left shift. If that is the worst of it, then I will adjust.
In regards to this, having 3 separate key binding dialogues which are even ABLE to conflict with one another is asinine, as you can need to look through all 3 to find the conflict, and cannot switch without making things first not conflict (possibly not even knowing what key it is that is conflicting).
...As such, I have merged all of the binding dialogues. there is now 1 for keyboard (instead of 3) and 1 for gamepad (instead of 2). This will be available in the next build of both 2.53 and 2.55.
Also, on a completely unrelated note, I've also added the ability to scale the size of the ZC/ZQ mouse cursor in zc.cfg / zquest.cfg respectively; with different scale settings for small/large modes. (The scale can be set anywhere from 1x (normal size) to 5x (...honestly far larger than you could possibly need, I just needed to set a limit SOMEWHERE)
Both of these features have been merged into the main ZC codebase (for both 2.53 and 2.55), so whenever Zoria puts up a new build, it should include both of these new features!
