Bubble Bobble ROM versions

[insx]

Hi Folks

I dumped the A78-21-1 ROM from my Romstar Bubble Bobble board and it contains the text "VER 1.1 4.SEP,1986 SUMMER". The only US versions I can find any info about are V1.0 and V5.1. Does this mean that there are a bunch of versions in between but only the first and last are mentioned?

Is there any problem running 5.1 on a board that doesn't have it or is it just like doing a software update?

Cheers

Contact mame to add your dump:

( I have a new ROM dump that I would like to submit)

It seems that my USA ver1.1 code is just the JAP ver0.1 code with the text at the end changed. They both have the same release date.

These are the only 2 different lines:
