New 27" iMac and Age of Mythology

Hello,

This is my first 27" iMac. What a beauty..

Does anyone still play Age of Mythology now and then on their 27" iMac?

Does anyone know of a way to allow AoM to play on the native iMac's resolution 27-inch (2560 x 1440)?

I tried manually adding the resolution by opening this file in Text Edit:

AoM>Contents>Resources>GameData>gfxconfig>geforce3.gfx

Didn't seem to work.

Any suggestions?

Thank you.
