I am just joining the HomeBrew community, I am getting a cheat DSI to hack and need help

1: how do I find games? (and game suggestions?)

2: what are starter tips, I just found out that hacking a DSI is cheap so decided to jump on?

3: any guide I can follow for a simple safe process?

4: what is a good HomeBrew launcher I should use?

5: dose DS HomeBrew work on the DSI

and if you got any important info I could use as a starter I need to know, I mean I don't know jack shit yet, so if like you got anything please tell me, I wanna get Spelunky classic, (og)Doom, and Wolfinstine...
