Read the DLDI article again, noticing the recommended method for patching with DLDI. You're trying to run a command-line application when you have no knowledge of the command-line, which isn't going to work. Look a couple of sentences above that in the article, as it tells you exactly what to use and how to use it (it really can't be much simpler)
EDIT: darnit, thought you were the guy who needed help with SNEmulDS. Sorry about that.
I'm not exactly sure why it's not launching at all. Do you have all the necessary files in the directory? Like the snesDS.exe program?
