I found a nice piano note key (A, C, etc) listing for it which made converting it really easy.
I did consider making this game myself, having done many remakes of old favourite games on Windows back in the 2000's, but these days it is a bit of a minefield to work on remakes as they are once again popular and have some value for the owners.
I also didn't know how I'd solve the problem of drawing and moving so many bubbles around at the time while keeping in one screen refresh (50 fps) or at worst two (25 fps). With more experience, I know how to better deal with that if I were to attempt it today. My advice is to go the full screen bitmap route for something like this and use XOR drawing for the bubbles and the players / monsters, so you can limit redrawing and moving to alternate frames. You can also use tricks like Jetpac uses and erase & draw lines in the sprite characters from bottom up in one operation to reduce the effect of raster refresh collision problems.
With some exceptional recent remakes on the Vic such as Prince of Persia, HERO and Arkanoid (amongst others), it would be great to see Bubble Bobble join that list so good luck and will be watching with interest.
