On a real YM2151 you need to wait a minimum interval between writes. You can check if the chip is ready by reading bit 7 of either address, it will be high when busy, low when ready (the emulator always returns low, so no worries there). Chase Vault has less/glitchy sound on FPGA hardware (it gets better over time played, but never perfect).
