Master Boy 2
|Master Boy 2|
This is almost certainly not a sequel for Master Boy, but only a 2.0 revision. It is unlikely that the title screen says "Master Boy 2".
According to Haze, wrt to the 1987 version of the game being dumped:
"This also very likely means the elusive ‘Master Boy 2’ is in fact just the version we already had emulated, it’s clearly a sequel to this 1987 game, but for whatever reason Gaelco opted to not put ‘2’ on the title screen. Anybody who had played both back in the day would have remembered the 1991 as a sequel, which is where the ‘2’ likely came from."
