(Forgive my low English skill)

I have two questions

1) Vanilla with bugfix

I installed co8 mod pack following instruction in website of co8, for bugfix
When I played this game after activated Circle of Eight mod pack, I can not found tutorial in game
I should go through tutorial because i will first play this game
So How can i play vanilla TOEE with only bugfix of co8 mod?
Should i reactivate TOEE but Circle of Eight mod pack at TFEX?
Then Can i play TOEE clicking GOG shotcut?

2) Widescreen

How can i set widescreen resolution?

Both and many other options are accessible when starting the game from ToEE Front-End X
which should have appeared on your desktop when installing.

In the front ends main window, just choose Temple of Elemental Evil instead of Circle of Eight Modpack

From "options" you can select the game resolution, some widescreen presets should be available.

Thanks for your helping
But I couldn't find any resolution of widescreen in game option although choose Temple of Elemental Evil in TFEX
So i just edited cfg file in game directory :p
