I have been learning and speedrunning this game the last 3-4 days, and I have a question if lag in this game is normal? Sometimes, you hit the button but it's like your input does not register if an enemy is shooting or lots of things going on in the screen. I know that most retro games are like that, and I understand it but when there is only a few enemies in the screen, game doesn't want to register the buttons you press. It's so frustrating! Is it normal? I'm playing on the original Genesis using RT5X on a CRT not a monitor.
