Intro
--

This is a nice glitch Pokédex mode which in Gold/Silver allows you to change the colour of the screen on the mode listing, after pressing A to change the menu to a different colour each time.

Stay tuned for a few more of these in the next couple of days :)

In Crystal it has a different mode listing effect; freezing the game instead, with possibly with a different freeze in the Rev A release of the game (white screen rather than black screen with Unown graphic observed).

In this video we use the Gold/Silver memory editor GUI created by Epsilon to change the current dex mode to 0xFE and view the effect.


What are glitch Pokédex modes?:
--

Glitch Pokédex modes are invalid Pokédex sortings and modes among the valid modes (New Pokédex, Old Pokédex, A to Z, Unown Mode) in Pokémon Gold/Silver/Crystal.

In the game, glitch Pokédex modes can be accessed in the expanded Balls pocket (by adjusting item 64 quantity however bytes may be shifted up afterwards*) via the duplicate key items glitch https://glitchcity.info/wiki/Duplicate_key_items_glitch or by accessing an out of bounds Glitch City (Crystal) https://glitchcity.info/w/index.php?title=Out_of_bounds_Glitch_City_(Generation_II)&stable=0 or with arbitrary code execution e.g. via a box name or stored items e.gs. Gold/Silver: https://glitchcity.info/wiki/Coin_Case_glitches or  https://glitchcity.info/wiki/Wrong_pocket_TMs_and_HMs (from duplicate key items via bad clone) or stack corruption ACE via bad clone https://forums.glitchcity.info/index.php?topic=8097.0

In Crystal the arbitrary code execution methods to get glitch Pokédex modes include: unterminated name/bad clone https://www.youtube.com/watch?v=VtRFxxKW7mY https://www.youtube.com/watch?v=YqD68-2aAjg   or wrong pocket TM/HM like in Gold/Silver 

Using a memory editor, D67E (Gold/Silver) or D959 (Crystal) will directly change the dex mode.

Alternatively GameShark codes 01xx7ED6 (Gold/Silver) or 01xx59D9 will replace the dex mode with xx's value.

*You can't toss from the item stack either, the quantity is locked. So the quantity must be from another item x254, and if the shift up occurs, it can be shifted down again until it's in slot 64. 

Dex mode 0xFE:

Dex mode 0xFE (quantity of 254) has the effects described in the intro heading above. But it is really just one of many interesting Dex modes, a collection of which can be found here:
