Full Byte of Keys

NOTE: I don't know if this code works or not. I have not had a chance to test it yet.

Someone emailed me with this question. If I understood the email correctly, this is what he wanted to know.

The Code

This following code will assume you've already strobed/reset $4016:

; after code is done, key will be in A ;--CODE START--; ReadKeyByte: ldx #8 loopKeybyte: ora $4016 asl dex bne loopKeybyte ;--CODE END--;

This Day In Review

My appologies to the person who emailed me about this, I had this file sitting around for some time. This file (if I haven't figured out if the code works yet) is part of my new policy of putting up things even if tests aren't done or are inconclusive.
