I was able to build cell9's NTR Debugger for OS X There is no point of posting my source code since I changed no line of code so here is the original source code: NTRClient I had to add IronPython and IronPython.StdLib packages to the project to have it compile successfully using mono Here is how to launch it: 0. Make sure you have mono installed 1. Extract the archive to /somewhere/in/your/filesystem/ 2. Using Terminal, navigate to the place where you extracted the archive like so Code: cd /somewhere/in/your/filesystem 3. Use mono to launch it: Code: mono ntrclient.exe Notice to Windows users: I know this is file has the .exe extension but you'll be better running the Windows release. My build might or might not work for you. I don't really care if it doesn't since this is build for OSX users. Bonus screenshots: PS. This has absolutely nothing to do with wine edit: can any mod prepend the thread's title with [Release] ?
