See the post, I attached a .NET quick throw-together to extract anything you want. Probably easiest to use Extract All. Compressed with MPRESS as I'd rather not see the effort lost, but if you want src, I can provide. Extracts resources as they are. Scripts appear plaintext, images are TGAs, etc. I did throw together a tiny UI to print some details out about each entry. I use a 4K-display, dunno if it will look right on lowDPI screens. I don't bother with DPI issues.
Entirely wrong. Almost all cracks do because people who crack games usually use packers to compress or help protect cracks from moron rippers and skiddies much like in the mid-2000s where a scene group would release a crack and some shit kid would try to steal it and the credit with it. Any decent AV would flag probably 9/10 cracks, though not always a viral. Sometimes merely flagged as compressed if the AV isn't able to decompress and sig it as perhaps a Diablo2oo2 (DUP) or AT4RE patcher, quick examples. But if it bothers you, either buy it or find original files and remove the steam_api protection yourself, then write a mitm DLL and crack it yourself. Not hard.
