This is a playthrough using Igniz in the Arcade version of The King of Fighters 2001. Read on below for more information...
Igniz is the final boss of the game, and he is a non-selectable character in both the Neo-Geo MVS and AES versions of it.
===== VIA DEBUG DIPSWITCHES =====
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. Igniz's icon (which is invisible) location is 2 spaces to the right of the Roulette [?] icon.
===== ABOUT IGNIZ =====
He is the NESTS Cartel's leader, having defeated the previous leader Nests himself. He has his own battle suit which gives him deity-like powers, featuring extracting whip chains for him to utilize as weapons.
Igniz is definitely one of the most powerful characters in the KOF universe... even though he is just a normal human with a battle suit, he's in the same "bracket" as Orochi, Mukai, Magaki, True Saiki, etc. and that's saying something.
===== KOF2001 IGNIZ INFORMATION =====
This wouldn't be a Krizalid99v2 video if I didn't include the technical information... enjoy:
---- 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 to the right of the Roulette [?] icon. He does not have an icon here which means that it's invisible.
---- On the character select screen, when Igniz 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 before you fight CPU Igniz)
---- On the Versus screen, his portrait banner is of a glitched sprite. As 4 of them appear, it slows the screen down.
---- If Igniz is selected as one of your characters and the others are other characters, the whole team will consist of 4 Ignizs anyway.
---- He always appears in gameplay as a lone character, meaning that he cannot use any strikers.
---- 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 same.
---- 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 Igniz, it also appears at the wrong place. It is supposed to appear after you beat CPU Original Zero.
---- He has a 2nd colour palette despite being a non-selectable character. You can see this at 19:14 in the video.
---- In gameplay, he cannot crouch/duck.
---- In gameplay, some of his Normal moves are similar to Original Zero's ones.
---- 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 INFORMATION /TRIVIA =====
---- 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.
---- KOF2001 is the only game in the series where there are no character names around the lifebar.
