Yeah. Tried that but I'm good the way it is. Works fine and any stretching that might be occurring is just not noticeable. At least to me. I play on a 1920x1080 monitor. The only thing I loved about using the widescreen hack was being able to alt-tab out, but I don't even miss that.

Does it include any patch notes? I'd like to know what stuff does it fix.

Yes, it includes a readme and a console_commands.txt. Here is a copy and paste of the readme;

Requires summoner v1.40

Copy dinput.dll and dinput.ini into the directory of sum.exe
Open dinput.ini in a text editor and set the options appropriately

A list of console commands is available in console_commands.txt.

Also-Judge Dan has a mod some of you might be interested in. It's a weapons/armor rebalance.

"All weapons have been rebalanced. Bows now do more reliable damage overall and several prices have been corrected. Previously broken enchanted weapons have been further repaired. Oh, and the spiked mace now does piercing instead of slashing damage."

Posts describing this mod in detail begin at post #56 I believe. I've been using it for the last week and so far game play has improved significantly.

I think it dosn't work anymore.
When I used this patch on the gog-version I become a "wrong version"-message and the game dosn't start =[

Well, worked for me. But no Alttabbing.
