You know that you're comically out of touch with your fanbase when you finally accidentally do something that makes them happy, and then apologize and say that you're "looking into it" as if their happiness is an issue that needs to be immediately rectified.
There's a good explanation for that.
In Japan there's a huge arcade competitive fighting game culture, and since share houses are rare, arcade players are likely to buy the home version to practice for the arcades. So the Japanese consumer expects top-notch AI which provides the challenge of playing another human.
However, what does the average consumer in America want? Fighting games are party games you play with your buddies at home. And people who play them for single-player mode are not looking for "training" for arcades, they're looking for a fun and paced campaign experience. Almost all enemies need to be beatable by Joe Average in at most a few attempts, or people start to get frustrated by lack of progression.
Sure, a small proportion of masochists would like the amazingly-good AI but most people don't want good AI because constantly losing to the same enemy feels like shit, and people play games to feel good.
I honestly have no idea what you're on about, but when I say that Super Turbo's AI is fucked, I mean that it's actually locked into the highest possible difficulty regardless of what setting it's actually on. Even if you set it to 1, it will be stuck on 8. This wouldn't be quite as big of an issue as it is if the AI didn't EXTREMELY blatantly cheat when on this difficulty. I tried it again just the other day and I experienced such fun things as
1: Guile charging up his moves instantly. Normally he has to charge for almost a full second before he can use a special move, but being able to instantly use them on reaction to anything makes him incredibly overpowered. I died to him more than the final boss and every other character put together. Also he can use flash kicks while standing up. He isn't the only character that can do this when controlled by the AI, but he's the worst example of it by a huge margin.
2: Dee Jay taking away over 50% of my life with one uppercut
3: Dhalsim oneshotting me with a throw (throws are unavoidable in super turbo btw)
4: Incessant button reading (oh you tried to attack? nah the AI just happened to magically hit you on the exact frame that you opened yourself up, git gud)
The Japanese version of the game does not have this issue, which is why people were pleased when they thought that they were giving the option to play that one instead. Even if the average American does have some kind of aversion to the not-shitty AI in the Japanese version, there was still the option to play on the American version. Them adding the extra versions to the game was probably the only time they'd ever actually done something objectively good that had pleased their players, and a day later they said "just kidding" and took the option away, to the joy of probably nobody.
There are still actual issues that have existed in the game since Day 1 that would have required practically zero effort to fix, and yet this gets "fixed" immediately. Third Strike had bugged audio on release, which caused stereo sounds to be played in the opposite channel that they were meant to. Fans found out that this was pretty much immediately fixed with a simple XML edit. However, in the next patch, this XML file was removed, with the devs claiming that the audio bug had been fixed (spoilers: it wasn't fixed. they just set the game to use mono sound instead)
I could write an entire full-length tragedy novel about the clusterfuck that is this collection and its release, but this post is getting too long so you get the idea.
