When playing either of these games you may normally get stuck after typing in your name, but some people have found a way to bypass this.
Once you start up the game on no$GBA, immediately click Utilities>Cheats>Add New and put in this code:
020DD9DC E1A00000
Name it whatever you want but make sure you make it an Action Replay code.
That should fix it so you can get past the black screen after naming yourself but if it still doesn't work, try the same thing with this code:
020DD9E4 E1A00000
If it still doesn't work then I'm very sorry but I have no further way of helping you.
Thanks to NintendoWalkthroughDude for showing me where this code was and for the people who figured this out.
