Do you know what IOS's you deleted?
I can see you don't have 202 or 222 - You were lucky that you didn't delete IOS70 that would have been a brick.
If you only removed the stub IOS's then i wouldn't worry to much - just backup your nand.
There is an option in [Only registered and activated users can see links. ] (scan wii internals) that shows you what IOS's you have installed and what version they are and save the info onto your sd card so you can post the results.
