Get the latest & greatest Chipamp

What will this installer do, exactly?

Essentially, Chipamp itself is just a delivery mechanism for existing Winamp plugins. When you install it, it will place these plugins into your Winamp plugin directory, so make sure you've already got Winamp, first. In addition to deploying the plugins, which Winamp will automatically recognize, Chipamp creates registry entries that associate chiptune files with Winamp, so that you can simply double-click an NSF or SPC and have it launch Winamp automagically.

What will the uninstaller do?

When Chipamp is uninstalled, the plugins are deleted and previous file associations, if any existed, are restored. You can install Chipamp over top of itself, but because the plugins included may change over time, it is recommended to uninstall first before reinstalling or installing a newer version.
