Glitch Evil Ryu
I’ve got a good idea of what’s going on here. Where this glitch is involved, player one acts as a source and player two acts as a mirror. This means whatever part of player one has this glitch involved, it will be reflected by player two if they also have this glitch involved.
The current things I know about are selectable glitch Sagat, selectable glitch Bison, A2 Ryu and A2 Evil Ryu’s move set. It’s like the game has a set path that all these… Pieces of code, lead into. When they come across each other they have an effect on one onother.
To start of the example we’ll use glitch Sagat Vs glitch Bison. Normally glitch Bison’s graphics are what look like Psycho Shots when he first enters interupted (before he’s invincible). What you instead see are Tiger Shots. When you knock him invisible he goes to his scrambled character palet. If glitch Sagat is player one, instead of seeing Bison you’ll see Sagat.
“If we flipped this round you’d notice glitch Sagat doesn’t mirror like glitch Bison. This is because you can’t knock glitch Sagat into invincibility where he’ll display another palet, like glitch Bison.”
This means player two is mirroring or copying player one. All four of the glitchee’s work this way, player two mirroring player one. As a better example we’ll use Evil Ryu (for new times sake) Vs glitch Bison. If we load glitch Bison from the first time so he’s solid, we’ll see Hadoken animation. Then if we knock him invincible he’ll have Ryu’s palet.
But here’s the brilliance. Previously A2 Ryu and A2 Evil Ryu don’t have a visual glitch property to have an effect on player two. But, if we flip the match around, glitch Bison Vs A2 Evil Ryu, we have a different effect. The visual glitch getting mirrored onto player two. Because of this we now get the result we know as glitch Ryu and glitch Evil Ryu (<well, you do now).
You can tell these four are connected to each other because any other character, that I’ve seen so far, doesn’t emit an effect or mirror an effect. I think this is because simply, they’re not involved in the glitch. I think the connection between the four is the character select screen.
Now here’s theory number two, same disclaimer again.
*Capcom orgionally had a few different touches to Hyper Street Fighter Alpha which got removed at a later date. Those touches where three characters which you select by pressing start on the game mode menu. Classic A2 Bison, Classic A2 Sagat and A2 Evil Ryu selectable buy changing the colour on A2 Ryu (not Evil Ryu) to red.
While they changed the way you select Evil Ryu and closed up the selection hole, they failed to do so on Bison and Sagat. While they also removed the data for Classic Bison and Classic Sagat, they didn’t need to remove the data for A2 Evil Ryu (selectable via A2 Ryu) becuase they already had the data in Evil Ryu himself. Since we can still select glitch Bison and glitch Sagat, the results are it getting leaked into Evil Ryu, where part of the problem exists.
This is why we get Evil Ryu’s move set, also why the character has A2 Ryu’s command list because that’s the character it was origionally selectable for. Also since you use the only move set left in the glitch (Evil Ryu’s), glitch Bison and glitch Sagat get limited to no super because they’re bound to Classic laws.*
I still don’t really know what’s going on, but the more you notice and look into it the more the pieces of the puzzle are fitting together. I’m going to play around a bit more but I don’t think I’ll find much more today.
