There was a pack somewhere with several cheat files someone created that did interesting stuff (eg: change spawn weapon, change fall damage on or off, etc). Maybe it's in Fonzie's modding pack.
The memory modding stuff is actually really, really, outdated. If you're still on 10.6 or below and operating on Halo Demo, the memory stuff may operate decently well. Otherwise, I recommend not touching almost any
of it including The Cheat, the memory mods, the memory modding template, etc. Modzy mentioned
there was a more up-to-date alternative to The Cheat called BIt Slicer, so you may want to check that out.
Regardless of what tool you use, just check the tutorials to grab an understanding of them.. Maybe once I get HaloMD on the road, I can focus back on the memory stuff.
I am no longer active to Halo or MGM, and don't guarantee a response on the forums or through email. I will however linger around the discord room for general chatting. It's been fun!
