I've found a widescreen fix that lets me play the game. https://github.com/ThirteenAG/WidescreenFixesPack/releases/tag/gta3

Can I use it during runs or is it prohibited?

I've waited for 3 weeks, it was 21st in the category, now its 22nd so mods approved someone elses run and still hasnt touched mine. How long should I wait until I message them? I don't want to irritate them.
