differences between neogeo CD models?

[c0ldb33r]

...Using a boot disc, a DC can play many Neo CD games/roms. It also tends to have better load times.

Interesting. I'd prefer to use actual hardware and games though. Could a DC with a boot disc use actual neogeo CD games?

Also, I'm 99% sure that you can use the joystick controller from an AES with a CD unit. Is this right? I really like the neogeo CD controller, but I'd like to be able to use joysticks too.
