IMO, I noted that most of the pc engine and tg16 was released prior to Konami taking over Hudson soft towards the end of 2011 , thus, I suspect, if there was planned more releases ( ie, similar to wii virtual console which released a few years before) then konami scrapped it, cos I noted that no new pc engine games was introduced to hk psn after 2011, same with tg16 which was a bit behind, worse still uk and Europe ( none at all)
