That's not even really true. The rom that most people use competitively was created because it makes things like score tracking above the ordinary limit easier. It just happened to also patch out the crashes (which were discovered later). It isn't like Dog said "I'll use this rom to avoid crashes". The community has mostly used this rom for years as their base choice already.

It's true when you advertise the accomplishment as being played on "NES Tetris". The vast majority of readers will assume this means it was played on the original NES Tetris. This kind of misreporting is especially bad because it will subtract from any level overflow achieved on the original game. Despite being a much more difficult task, if somebody does manage it, it will get less attention because the reporters made it seem like it already happened.

Most records set in NES Tetris up to this point, including those that have been reported on, have been set on this mod.

All of these communities set up norms and it is weird how every time any news breaks out of them it is stuff like "wtf he is playing smb1 with a keyboard that doesn't count" while all the people actually involved in the community are just shrugging their shoulders.

Previously reported NES Tetris accomplishments did not involve modifying the game to bypass an extremely difficult part of that accomplishment. Fixing a score display bug makes almost no difference to how the game is played. Similarly, playing SMB1 on a keyboard makes very little difference to how the game is played. All the challenges of the original game are still there.

Wrapping the level counter on Tetris Gym is difficult and impressive. It is not however the same thing as wrapping the level counter on the original NES Tetris, which is what every reasonable reader who's not involved in the Tetris community will interpret "NES Tetris" as. Tetris Gym was accepted as standard before people could reach the crash levels. The fact that it previously made no real difference does not excuse continuing to call it "NES Tetris" now that it does make a major difference.

I guess I personally care much more about what the tetris community counts as NES Tetris than what other people think.
