When you try to open the halo portable, you can only see the words Halo but not the menu, and about 30 sec later you hear music? Also does a warning pop up that says that you need to turn off anti aliasing? Also this is the school halo port.
If you cant find any way to fix it just dl the halo portable Custom Editon. Unlike the school one, ppl have this so there are always posts about it. An annoying thing about scool port. is that when it extracts, it extracts to a TEMPORARY folder which cannotbe altered. haloCE extracts to any folder you like and it is same amount of space required as scool port. ( for ppl with 19 gb harddrives lol)
after installing Halo CE jsut go control panel and go nvidia control options and go to halo CE (after adding program to this folder) then go antialiasing and instead of 2x make it controlled.
after this jsut play andpress esc as son as you see halo words or if you wait 10 sec its ok
