Re: [stella] Climber 5 RC#03

Exactly. LDA does an implicit

CMP #$00

so the flag content you were expecting was destroyed.

I bet you have used this as a "feature" a zillion times as in
LDA someState
BNE / BEQ somewhere

LDA affects the N and Z flags, so you can do BMI / BPL as well as BNE BEQ, but I have never seen where it affects the carry.
