HOW TO USE THIS EMULATOR
--------------------------

You must include the BIOS (512k) on the on the root directory of the CD. you must wait till the musci stops before swaping a game or count 15 secs

What you have to have is a NEOGEO CD game. Boot this up and you will see the boot screen.
Open your dreamcast lid, remove the emulator, then place the NEOGEO CD in. Close the dreamcast
lid. Wait 30 seconds (or less) just so the GDROM drive spins back up. Then press start.
If the game works (for example: puzzle bubble) then about 10 seconds after you will see the
game load up.
