On Christmas day Pixelboy from AtariAge released a handful of Colecovision roms here
http://atariage.com/forums/topic/247116-team-pixelboy-news-bulletin-december-25th-2015/?p=3399780one of them supports saving on an EEPROM, i know that one game is already supported and saves to the sd card (i cant remember the name of the top of my head)
I was wondering if support can be added to allow this new game to save too?
I can post the rom here if it helps?
