Second dont say this is old, b/c they're have been other ways posted but not his way.
This is the easiest way, and only requires 2 things.

Requirements

    

* Multiman 1.17 - 1.17.4

* Game backup

Steps

    

1. Open multiman



2. Copy the game to INTERNAL harddrive



3. Go to game settings



4. Select Internal, and direct boot (bottom left of screen)



5. apply and go back into game settings



6. Set permissions



7. Apply and press X on the game! you can now play

NOTE

    

* some games require to update through multiman to play

and yes, you dont need SELECT + X

Simple and easy

This is pretty easy to do, so dont say "I already figured this out" (thats cool, no one cares)
This is just a tutorial for the people who dont know how to do this, and Im just being helpfull.

If you came here to flame then GTFO, I dont care about your anger :FU: just leave.

I try it with Sonic´s Ultimate Genesis Collection and not work. I get only "black screen"!
