Recently i got pre-production prototypes of Mega EverDrive PRO, going to finish all works in 1-2 months. Everything working already, just need to finish work over save states and polish this all (: pic.twitter.com/Rcg83hlpoc
While developing MegaSD we tested it with numerous Sega CD hardware attached, but disabled CD loading in the UI because every time a cd register is read, both cart and cd answer causing a bus conflict. So to play it safe we wanted to avoid any risk of damaging expensive hardware.
