Hi! I've been exploring Joy Van's NES catalog recently, and I of course came across Master Chu. I was curious about the Chinese variant, so I found a copy and decided to play it through. However, unlike the US version, it works fine for the first level, only to turn into a glitched mess afterwards. I'm fairly certain it's using the tile / sprite set from Level 1, so it must not be switching the banks. Does anyone know why this happens?
