I still don't get what the huge focus is for using USB for classic gaming.
IMO, it's more of an "amiga lego" then a retro game machine. One could just use EUAE for OCS/ECS games, or one could use a Minimig and expand it beyond what the creator's initial intentions were for it. I think it's the latter that have the eye for USB capability. Like what the C64 folks do, take their machine far beyond what it was doing in 1980s.
Sure do have fond memories of my upgrade ECS A500 with baseboard RAM, Supra 28MHz Accelerator, Dataflyier SCSI with RAM.
