Depends on whether the batteries were hooked up in either series or parallel. Later GameBoys only needed 2 batteries but required the same voltage, so I’m guessing that the OG GB is wired in series-parallel.
So in other words, you need at least two batteries to be good for this to work in the OG GB. Later editions need both batteries to hold a charge to reach 3V.
