is there complete guides or multiple guides that cover everything you need to speedrun MGS4 NG and NG+?
Not that I know of, but it's best to ask some of the runners / people with knowledge about the game (strafemachine) and watch a lot of runs. That should help. Maybe someone will make a guide someday.
As MiniOmegaKing said, there are no written guides for either NG or NG+
All the information was mostly shared between the runners. There are a few old videos for strategies on wolf and the explanation(s) for the resistance trick.
There was never any demand for full guides as this game isn't the most popular in terms of speedrunning.
Your best bet is to try and get into contact with runners for the category you're interested in.
Watching the segmented runs has little value as you'll be trying to replicate until you hopefully understand why exactly things are happening.
There's a discord channel, by Strafemachine, where you're most likely to get information.
RPCS3 emulation now has a board for running! This marks a big step in terms of accessibility for running MGS4, and while the emulation isn't perfect by any means, this now gives runners who don't have access to a PlayStation 3 an opportunity to compete.
Now to cover a few ground rules for competing
