This week we figured out why the sprite 0 code was slowing things down for the game when there were lots of entities on screen and then we figured out how to change the game to run with mapper MMC3. I wasn’t able to get the scanline interrupts working properly yet but we’ll get that handled on Thursday. Thanks to those who watched!
