Uh, Scramble Formation and Tokio are the exact SAME game. Flipping a dip switch causes it to change the title (and place names change from english to japanese or the inverse).copados33 wrote:A bit off topic: I have an original Tokio PCB, would it be possible to convert it to Bubble Bobble? same hardware as Bubble Bobble, the western version of Tokio a.k.a. : "Scramble Formation" doesn't have the Z80, but Tokio has it.
The board has Two Z80Bs (next to each other) one Z80A (at the opposite side as the other two Z80s) and a protection MCU (the MCU is at about the middle of the board).
The sound hardware is very different (Scramble Formation/Tokio lacks the YM3526) from bubble bobble and that would be a bit of a challenge for the conversion.
And... Scramble Formation is actually the Japanese name for that game. Tokio is the "overseas" name. (Trivia: Tokio is an alternative spelling for Tokyo and also how the city name is written in Portuguese)
