SGB border is sometimes corrupt #440

BGB has a "GBC + initial SGB border" system feature that initially boots in SGB mode, then reboots in CGB mode once a border has been loaded. However, the SGB border graphics are sometimes corrupt, and the game has to be reset a few times until they look entirely correct.

Isn't this a BGB issue?

I haven't seen it happen with Gold or Silver, so I suspect it's an issue with how PC copies its data to the notional SGB cartridge. Note that I ported the code from pokered, not pokegold, since it was completely disassembled.
