Notes : In 1985 Konami decided that it was going to experiment with a new state of the art program storage system to replaced ROMs. This was called "Bubble Software".
Other manufacturers had already operated magnetic media (disks and tapes) instead of roms with some success, so Konami decided to make a modified version of their own new G400 BIOS system.
Bubble memory is non volatile electromagnetic writing/readable memory and was thought to be, at its inception, as a direct a quick replacement for floppy disks.
Unfortunately Bubble Memory proved to be extremely susceptible to electromagnetic fields (not great for something in a arcade enviroment) and were also more expensive than standard ROM based boards. For this reason the project never got beyond its first couple of games.
Anyone who still has one of these systems in their possession and still has it working today is incredibly lucky...
You can tell bubble soft games by the startscreen "wait while system heating up", because the BM needs to be heated up to between 30-40 degrees to work properly.
