So, I was comparing alfred the chicken on the gameboy with the nes version, (Which is a direct port) and i noticed things like the stars on the title screen only lag on the nes, and not the gameboy, and thats not all, because when I started to play the game on the nes, I started to see some lag that wasnt present on the gb version. To test this, I was using fceux, with the the lag meter tuned on, and used bgb, while watching the dmg cpu usage bar, which hardely even reached the top. So this might be due to the nes being weaker than the gameboy, with the nes having a slow clock speed of 1.789773 mhz, while the gb has a blazing clock speed of 4.1942mhz! Almost 4 times more powerful than the nes, and even a little faster than the game gear. But I know that this is an unfair comparison going by the clock speed. But still, I am pretty convinced that the gb is more powerful, because of these things. Feel free to reply your thoughts. Also I am saying that the nes can't run sml, because super mario land already slows down on the og gameboy due to the poor coding, because it was a launch title, and if the game engine were ported to the nes, it probably will come to a stop before you even beat the game.
