King of Fighters 2001 [Arcade] - Original Zero

This is a playthrough using Original Zero in the Arcade version of The King of Fighters 2001. Read on below for more information...
Original Zero is the penultimate boss of the game, and he is a non-selectable character in both the Neo-Geo MVS and AES versions of it.
===== VIA DEBUG DIPS =====
One of the external methods to select him is by adjusting the system's Debug DIP settings, which is the way I did it as shown early in the video. In order to get access to the Debug DIPs, a modified Neo-Geo BIOs must be used.
If you have access to the Debug Dips, the switches to enable are 1-5. Do this before you reach the character select screen. You can then disable the switches on the character select screen. Original Zero's icon (which is invisible) location is 1 space to the right of the Roulette [?] icon.
===== ABOUT ORIGINAL ZERO =====
He is the real Zero, whereas the one in KOF2000 was a clone of him. Despite him being a high-ranking executive of NESTS, he is an honorable man and a good guy.
O. Zero is definitely one of the more powerful characters in the KOF Universe... he's in the same "bracket" as Omega Rugal, Goenitz, Krizalid, Clone Zero, Dark Ash, Nightmare Geese, Maki (maybe), etc.
===== 2001 ZERO INFO =====
Here's the technical information on his operation:
---- On both the 1-player and 2-player character select screens, his "portrait image" is glitched sprites of other items.
---- On the character select screen, his "slot" is 1 space to the right of the Roulette [?] icon. He does not have an icon here which means that it's invisible. Obviously, this slot is usually non-accessible.
---- On the character select screen, when Zero is highlighted, his name says "ROULETTE?".
---- On the character select screen, his post-select icon (which appears next to the portraits) is glitched.
---- On the order select screen, he actually has his own proper icon here, despite being a non-selectable character. (normally you don't see these icons here before you fight CPU Zero)
---- On the Versus screen, his portrait banner is of a glitched sprite, and his name is "ROULETTE". As 4 of them appear, it slows the screen down.
---- If Zero is selected as one of your characters and the others are other characters, the whole team will consist of 4 Zeros anyway.
---- He always appears in gameplay as a lone character.
---- If he is selected as the 1st character in your team and you play through single-player mode, the path near the end is wrong and will eventually freeze the game.
---- If he is selected as the 2nd, 3rd or 4th character, it is possible to play through the whole game with him in single-player mode. However, after defeating CPU Igniz, the game will then loop a cutscene over and over which means that the game cannot progress.
---- The cutscene that appears and loops infinitely after beating CPU Igniz is actually the Hero team's pre-fight-to-Igniz cutscene. Not only is it wrong for Zero, it also appears at the wrong place. It is supposed to appear after you beat CPU Zero.
---- He has a 2nd colour palette despite being a non-selectable character. His Strikers also have different colours. You can see this at 19:03 in the video.
---- When setting him up on the order select screen, the other 3 Zeros must be selected as Strikers, otherwise it will freeze the game if he tries to call the ones that are not set as Strikers.
---- In gameplay, he cannot crouch/duck. But he does have a semi-crouch-block animation.
---- In gameplay, some of his Normal moves are similar to Igniz's ones.
---- In gameplay, he always has the 3 unique strikers - Ron, Glugan and Krizalid. They are also summoned using unique commands that are different to how a regular character summons a Striker.
---- In gameplay, even though it appears that he has no super gauge, this isn't true. He actually does have it, it's just that it's invisible. This is because he still needs stocks to perform his super moves.
===== ADDITIONAL INFO / TRIVIA =====
---- Despite being a headswap of Clone Zero from KOF2000, Original Zero actually has less animation frames and less personal moves.
---- He appears in 2001 because the supervising designer was not happy with Zero's design in 2000. The designer also hints that this design and the lion were already made back then but were not used.
---- In the game's intro, when the grid of the roster appears, Krizalid and Ron appears in it, despite the both of them being non-regular/just Assist characters. Therefore this makes Original Zero, Igniz and Glugan the only three characters to not appear on this grid.

16:59Chain Blade Transaxial Slice is a great counter attack against the beginning of Slice.😊

What the hell is that glitched Striker Joe?

[@cloud_s_97]

Possibly a leftover from kof 2000, especially the kof 2000 Joe striker..
