Programming / 65815 BIT immediate
« on: February 24, 2015, 10:48:39 am »
Hello, new to the board. Just as a pet project I'm trying to write an SNES emulator in Javascript to run in the browser. Not sure if it's going to work or not, but ehh, it's fun.

Anyway, I'm trying to emulate the opcodes at the moment, going off of this doc:

http://wiki.superfamicom.org/snes/show/65816+Reference#fn:2

For the BIT operation in Immediate mode it says it only uses 2 bytes, but I'm wondering if this is true when the Accumulator is in 16 bit mode as well? Wouldn't you need 3 bytes for that?
