lol...
Sorry but Lol.
You would do well to fully follow every little step exactly as told by heimdall..
Il give you a summary of what hes telling you so you understand why hes telling you these things..
When you have a softmod from a game exploit it is usualy old. So we update them.
You use the hexen disk to Update the softmod, it does this by 1st deleting the old softmod then installing the new one to do this you 1st select the option in hexen, it then does its thing and makes you back up your eeprom. when its gone to the next screen you select the back up eeprom option again and it will say "Backing up eeprom

" then you use the back to settings menu option and you will see a "basic install Unleash-x or similar option" that will then install the updated soft mod for you and make you a nice safe shadow c.
After you have done that You can then go back to hexen and use the hexen options to change your display settings to ntsc. you simply press a or b like the thing tells you. then restart. if you can display ntsc on your tv when you restart the picture will be good so you can then go back to hexen and enable the hd video modes..
Now thats the basic version.
if you want to be able to do it you need to read carfully what your told and do it exactly like told.
Any time you think Hmm.. im stuck, il just reboot.. say "WAIT STOP, did the instructions tell me to reboot here?? I better go double check them. and if they seem unclear I should ask a question and get an answer before rebooting"
Good luck.
and have fun heimdall. Il be here chuckeling in the shaddows.
