"Eyes & Lichty" is scene slang for the excellent manual "Programming the 65816 Including the 6502, 65C02, and 65802" by David Eyes & Ron Lichty. It may be the best unofficial textbook on SNES programming, due in no small part to the fact that the Ricoh 5A22 is based on the 65c816 and the SPC700 is based on the 6502.

Eratta

page 497 recommends making sure the carry flag is already set, or to set it with SEC prior to doing a SBC to "avoid subtracting the carry flag" but it should say "to avoid subtracting one"

In the tables that show which MPU supports which instructions, an "X" denotes yes and a " " denotes no. Many readers would find a check mark less confusing.
