Does pogoshell/moonshell work on the EZ3?
Yes (the EZTeam sent pogoshell’s author an EZ3 to play with) although why you would want to use it I do not know (EZPDA most of what pogoshell does, emulators all have injectors and anything pogoshell does can be replicated using other programs) and you should use the more current versions too. Moonshell is designed for flash carts using external memory carts e.g. M3,supercard,EZ4 and so will not work.
