Rollercoaster Tycoon 3 GOG

Hi,

I just purchased Rollercoaster Tycoon 3 from GOG. Does anyone know how to change the resolution to 1080p? I have searched online for a while but can only find results for non GOG, so I cannot follow the same instructions. I cant find any files in the folder that will allow me to manually change the resolution. 

If anyone can help that will be great! I am using windows 8 btw.

Thanks!

Really? that sucks. Ive been playing it in the standard resolution its given me, it would have been nice to have it in 1080p tho but never mind.

Classic game!
