Why do you have a game files on your desktop? That isn't a suitable location.
May I suggest moving it to a more suitable location e.g. C:/Games/Iw4x

Emblem / title data is stored in your stats file, your stats file is saved to the players folder in your game folder. The only reason your title and emblem choice isn't saving would be because the game can't save your stats because it doesn't have perms to do so.
Is your MW2 game folder by chance in program files folder?

I just downloaded iw4x too and I noticed this too, I was worried but I hope it will be fine

I think I found a way to avoid this. If you reinstall the game, and then never open MW2 multiplayer from steam, avoiding the first time setup and just launch from the iw4x app, I don't think Spacewar shows up

I believe the code just checks if it's in your library aka purchased.

is that all mods? just 3 mods?

In this post yes. For the whole of IW4x no....

My thoughts are that he is a troll or just plain dumb. If you read/listen to what he says, he just strings words together that I doubt he even understands himself...

Punkbuster

? MW2 Steam doesn't have Punkbuster, it uses steams VAC. I believe Call of Duty 4 uses Punkbuster but not MW2. He is mistaken.

They copied Fallout 4's skins

? No idea what he is talking about, he provides zero context.

can ban you from Steam for copyright

? Again zero context and has no evidence. This is not true. IW4x is a mod for MW2, it's not a copy and no you cannot be banned from steam for using it...

Uses pirated copy

? It doesn't, it requires a steam copy of the game. Again no evidence, just false accusations.

Don't download from pirate bay

? Well yeah don't, you should use your steam copy of the game. Again not sure why he mentions it just seems out of context.

itself infects you with a virus

? He provides no evidence. Yet another empty claim. The project is open source so anyone can review the code and even build it.

These are the ramblings of an idiot or a mad man. His videos just make him seem foolish for pretending to know more than he actually does. I tend to avoid the Steam forums as there are many of these such people who just circle jerk each other.

It's perfectly safe to use. It's used in development for new games etc.

Some mod likely disabled it. (Only badly coded mods do this....)

You will need to either reset your config file (.cfg) or use the console to re-enable hitmarkers. I am unsure what the dvar is called so your best bet would be asking in the IW4x support channel or check the IW4x website for what it is.

No, nor should you be using a machine connected to the internet that's running Windows XP in 2020

You have to edit the the games code +reverse engineer) but it wouldn't be advised due to stability issues.

Basically you cannot do it via dvars or gsc.

The players folder contains all user data, you can just have two copies of these and just rename them when you wish to switch profile.
