YouTuber hoscarconh brings you an awesome, almost unheard of, system the Konami Bubble System, an arcade system board designed by Konami and used in many arcade games across 1985.
The Bubble System was supposed to have a unique new form of data storage for arcade-style video games. It used bubble memory cartridges, a sort of non-mechanical magnetic storage system. It was said to have a higher reliability than mechanical floppy disk or tape drives.
This awesome download is around 25mb and contains everything (Except the emulator – uses MAME) you need to add this to your system. It seems that hoscarconh is paving his way for a great name in the scene, releasing this and other decent sets, (if you are reading this please get in touch!)
