Of course Harry could/should move this to Help & Troubleshooting
The Oni Galore page on the wiki is indeed a good place to start.
You can also search the previous forum for "thedayismine" or "dev mode" or "developer mode".
You'll find a few "old" threads with highlights of the Dev Mode, instructions on how to get it to work, overview of the features, etc.
I may add a few links to recent versions of the EXE (with not only Dev Mode but a few unlocked controls, widescreen support, etc... well there's not much of an "etc", actually )
