WIll an r4 work without moonshell?

My moonshell is not working on my r4i SDHC, and it takes away too much memory space. If I delete it, will my r4i still be able to play games?
(I only care about the games, no other r4i feature is worth it to me)

yes it will still work

yes

moonshell is a media player. If you delete it you will not be able to play videos or mp3s, but your flashcart will still function normally.
