// Update 2022: sub CPU doesn't seem responsible for sharing code to main,
// and bit 7 write to 0xca00 happens after that main checks it out during attract.
// Notice that main CPU just fakes the ROM checksum check at startup, just drawing ROM # OK at PC=0x1726
// There's also this (nsfw link) -> https://sudden-desu.net/entry/tee-d-off-a-saucy-secret-and-hidden-dev-credits
// which implies that at least 1 ROM is bad here.
