Exemusic Recorder

WHAT?

Exemusic Recorder is a tool originally written to record music from certain programs, such as EXEMUSIC or 4/8/16/32/64 kB intros, a common trait found in the demoscene. It has some extra features that might or might not be helpful when analyzing programs (intros). If you have no idea what I'm talking about, this tool is not for you.

USAGE

I really hope the UI is self explanatory. Select executable, arguments & output directory, choose options, press start.

Most functions are just added for fun and curiosity - you can use this to find out what certain intros do, what files and DLLs they load, how they call certain APIs... It might have been used to analyze malware, too - but don't take my word for it, and always make sure to run those things in a VM.

TROUBLESHOOTING

If the target application crashes, try if it's related to certain options. If the binary has relocation info, remove it using stripreloc. If all fails, click the "Executable"-label a couple of times until the "Experimental" options show up.

Simple Injector: enabled by default, disabling it will use a more complicated (and potentially more troublesome) injection method that should ensure injection before anything else from the target binary is executed. Then again, so should the simple injection method.
Slow Wave Writing: enabled by default. Writes large chunks of audio buffers to disk as it if were playing in real-time. This is basically a fix for 4klang when a single large buffer is allocated, passed to the audio api and then filled - this option might cause problems in other scenarios.
Hook into spawned processes: Use this when encountering droppers that spawns a new process. e.g. obscure packers.

"Double Speed" might cause problems if your CPU is too slow (or your soundcard does not support twice the samplerate). Use "Half speed" instead.

If all of the above hints are stupid and didn't help, you're out of luck. You can file a bug here.
