Will this work with my game version?

I have played all of the older Halo series before. This worked nice to refresh my memory on the story line.

Alt+Tab was my fix. Everything works great, just as the instructions direct. Thank you.
Very hard to get game to launch and have Wemod work. Can you fix this so that when you launch the game from Wemod the game will start with cheat enabled?

Worked well on Halo 3 but completely non-functional on Halo 4. I am going to test on other games. I would purchase this but will not pay a monthly subscription

works on both steam and the xbox version you just have to find the executable for the xbox version and run with anti-cheat disabled
