Almost work on Winamp 2.95 about wdrp HOT 2 OPEN

Thanks for reporting this. I wonder what's changed between that version and the tested ones. I'm swamped with my day job work right now so it might be a ways out before I can debug it, but if you're motivated you can definitely you can attach a debugger to see what's going on, Winamp is debugger-friendly. The plugins run in-process and nothing bad happens if you halt execution. To set it up, you build from source to get symbols + plugin binary. Copy the test binary to your plugin folder. Then debug winamp.exe with Visual Studio or your debugger of choice and ensure plugin symbols get loaded. The source code's Visual Studio project has some leftover stuff for this, from what I remember. One thing I remember being fussy is what the actual plugin interface was. The plugin API for Winamp was only like 50% documented. Some of it I had to get through experimentation or looking at other plugins. So maybe there's a behavior that the plugin relies on which it shouldn't.
