Hey eightbit,
I'm sorry you're having so much trouble. To address your problems:
-When I run ETconfig emutron general config and launch script wizard are grayed out
The Emutron general config and the script wizard are not quite ready for prime time yet. The disabled buttons are intentional.
The general config basically sets up the etoption.cfg file for you, allowing you to pick the script you want to start up with, setting screen size, key repeat rate, etc.. You can do this by hand(it's not hard)
The script wizard is a work in progress, It promises to write the scripts for you via a point and click , drag and drop interface. I hope to have it ready soon

-When I launch game catagories I'm not sure what to do with it, rom path won't let me select or type in a directory its looking for a file name.
You have to use the browse button to select your rom path, And once you're in the rom path, you have to click on a rom file(I know , I know, this is not-self-evident) ETConfig will get the path from the file you click on.
As I type this, I'm working on an in-depth faq file on how to use the etconfig program and how to set up game lists. I'll copy and paste it at the bottom of this post.
-I can't get emutron to show anything except some default aircraft game list.
The current script you're probably running (mame.cfg) is set up for multiple catagories, the way to move bettween catagories is defined in the script. Here's the piece of code that defines it:
EVENT NextCategory
KEYDEFS
SCAN_LCTRL
END_KEYDEFS
ACTIONS
SaveState()
NextInList(categorys,1)
fireevent("LoadCategory")
END_ACTIONS
END_EVENT
So if you press the L_CTRL (aka left control button) on your keyboard, you can move on to the next game catagory. You can change this to be anything you want. I have defined all recognized key codes in the etscript.rtf file at the bottom. You can use mouse movement, joystick, gamepad, or keyboard.
Take a look at the scripting language to set up the script the way you need it. I know it's a little in-depth, however I want to be able to provide the flexability you need to configure / run multiple emulators /multiple catagories/ and multiple skins.
Basically, Emutron reads in list files, These list files are arranged in "columns" of information like a data base. Then, each column of info can be referred to in the script code for the current row. Each list can be 1 -10 columns wide. Based on the column info for each row, you can generate screen shot names, art file names, screen text, etc...
I hope this all makes sense.
I'll be posting a link to the FAQ file I'm writing very soon.
