Project mention: Block YouTube Ads on AppleTV by Decrypting and Stripping Ads from Profobuf | news.ycombinator.com | 2025-03-18
I don't have any numbers, but I think this is still pretty common. On iOS for example Alamofire which is a popular network stack, still offers this as a feature. I think the use case is a bit different for apps and web sites, especially for closed ecosystems like Apple's where reverse engineering is not as easy/straightforward.

"Emulator" is the wrong word, but the answer is yes. The word you actually meant was "re-implementation" - writing a completely new, clean-room program which reads Source data files (levels, assets, scripts) and allows the user to play a Source game is perfectly legal.
It is necessary to avoid distributing any copyrighted material, so the user must provide the game assets from a legitimate copy for using the program to be legal. In addition, the 'clean-room' must be maintained by ensuring that no contributors to the re-implementation have ever seen the source code for Source, or they become tainted with forbidden knowledge.
Indeed, it's quite common for beloved old games to be re-implemented on new codebases to allow easy play on modern OS's and at high resolution, etc.
