Dunno if anyone's posted this, but apparently, a long while back, someone found a way to hack into MK4 for the PC and alter the graphics and sounds to it. The project (which apparently had a small following) was called MK4Strip/MK4 Enhanced, and could be downloaded from http://web.archive.org/web/20031211063126/http://www.sorcerersoft.com/mk4strip/ Well, the original owner of the project's not working on it, anymore, but the project's still available for download (the link provided is to the archive.org-saved version, since apparently the download link to the normal version is broken). Just thought you MK4 enthusiasts should know about it.
