Burger Time (NROM) - black screen

This looks like an emulator issue with PPU timing, but I'm not 100% sure. The game seems to get stuck reading PPU status and looking for bit 7 to be true for an NMI change

Resetting the game fixes it. Maybe initial state isn't right, or a race condition happens around the initial reset after cartridge assignment

setting nmiDelay to 16 instead of 15 seems to fix it, and as far as I can see, doesn't impact other games. I'll keep nmiDelay at 16 for now and close this issue
