Dumb question. Can you do a rough X/Y scroll split with 2 writes to $2006.
Of course you can. Most games do it that way. My game does it that way too. Fine X scroll stays the same.

This is the "standard" way to do it. All games does it that way. The 6-5-5-6 method was only decovered by the reverse-engineering retroscene in the 2000s.
