In NESdev Discord server, Sour wrote regarding sgb_boot.asm:

this replacement sgb boot rom broke the borders in tetris dx in the end I figured out that it finishes the boot sequence much faster than the original boot rom. I hacked it a bit to make it finish in more or less the same amount of time and that fixed tetris (in mesen at least)
