This article has a talk page!The Neo Geo CD was SNK's entry into the CD-ROM-based console era. Plagued by loading times due to its 1×-speed CD drive with inadequate CD-ROM cache, SNK would go on to release the upgraded CDZ model equipped with a 2x speed CD drive, albeit without 2x speed loading times due to CPU data copy inadequacies.
The absence of any region-locking made the CDZ the preferred model for importing.
Startup Easter Egg#
Pressing Up, Up, Down, Down, Left, Right, Left, Right, Down, Left, Up, Right, Down, Up, Down, C during the startup animation brings up a blocky "SNK NEO GEO" text display. No other function seems to be triggered with this sequence. This is not present on the Neo Geo CDZ.

Holding Up + Down + Left + Right (normally impossible) on any joypad during power on starts up the complete system test routine.
Unused Neo Geo Logo Jingle#
On the standard Neo Geo CD, a normal Neo Geo logo jingle is present as track 0x02, but it's left unused. The normal Neo Geo CD jingle is track 0x30.
This is not present on the Neo Geo CDZ, where it was overwritten with the used logo jingle.
