Hidden content
From NEC Retro
Hidden content refers to content that is not documented in any instruction manuals nor seen in normal play. This can range from cheats that require the player to input hidden passwords or button sequences at certain points, Easter eggs programmed in by developers for clever players to find, debugging tools, unused code, or even features that had to be cut due to developers struggling to get a game in stores by a certain date. More often than not, scrapped features can be accessed using in-game cheats, through the use of cheat devices, or by hacking/datamining.
This category documents all of these hidden tidbits found in games released for NEC systems, be it cheats, unused graphics, music, or otherwise. This does not include content unlocked in normal play unless there is a hidden code to unlock it immediately.
