Given Naka-san, SEGA was employed by SEGA at the time I would guess if needed he would have been summoned to over Japan to help on the coding side or at least take a call for any team member needed help on Sonic CD. Failing that I don't see why the Sonic Team in Japan couldn't have come up with their own engine and design for the boss stages, much like they did with special stages Jon said himself he had nothing at all to do with the Mega CD version of Puggsy; I think that happened with a lot of Mega-CD titles Where the main team were different from those who worked on the Mega Drive originals. I'm sure that was the case for the like of Fifa, Sensible Soccer Ect, not that looked to change much in those mind other than add in PCM soundeffects and more animation in Fifa I don't see how a tiny team in the UK could have a better grasp of the Mega CD hardware, than the staff working inside SEGA Japan, where you have the people who designed and made the hardware inside the very same building, never mind Core would have needed to put up with poorly translated doc into English that you had back then. It just came across that SEGA Japan consumer teams were overstretched and just put more of their effort into the base system, since that was where you were getting the best sales, but I don't know and its all guess work. So many of SEGA Japan Mega CD tiles felt cheap and quick like their Mega CD baseball and golf games. Also, I remmeber the Red Access light being used when you get that time traving screen, so I would guess its loading in some data, maybe just for the PCM music on the past stages. I maybe have to double check on that mind since, its been so long since I played Sonic CD on a model 1 Mega CD . Either way, Sonic Team should have just used the PCM chip for a much better sound effect. I can't belive it was used in the game myself, it was horrible. I'm not having a go at you btw or trying to wind you up . I just felt SEGA Japan could and should have done far better with the Mega CD and felt bitterly letdown by SOJ. I love SEGA and love the Mega CD and just was hoping for so much more from them on the system . SEGA Japan on the Mega CD were very much like Sony on the PSVR. In that SEGA didn't have many of their In-House teams making AAA projects for it and left it to 3rd parties for the main and like with VR on the PS4, when the Mega CD was used to its fullest, it was an amazing experience.
