G1 seed generation may be faulty about shiromino

Sure. The more info, the better. If it's possible for to provide a video demonstrating this behavior, that'd be helpful.

@gregorulm Just committed a change that might have closed the issue. You were right about the seed not being very random between games. Before that change, the value of the seed on game over from the last game would be used for the next game. I changed it to constantly keep changing the seed nondeterministically while in the menus, so you'll always get a very random seed every game. The change applies to all modes, as the previous non-randomness was occurring with all modes.

Though the supposed same-initial-sequence thing you observed could just be seeing a pattern where there isn't one, because the seeds do change pretty randomly every time the randomizers are run, so the seed on game over of one game that got used for the next game wouldn't be similar to the previous game's initial seed. But the change I made is still appropriate, and is the "right way" to initialize the seeds before starting games.
