Now that we have the proverbial "Tower of Power" would there be room in the FPGA chip to merge all three together and maintain a single core instead of 3 separate cores with folder structures?

I would also assume getting all three merged would allow the few remaining CD/32X enhanced games to run as well?

The whole reason a Mega CD core exists is because of the difficulty of fitting it together with the SVP chip + turbo features on Genesis. Adding the beefy 32x processor just compounds those difficulties.

It's more than just size. Genesis uses several chips that are coordinated by a bus arbiter that kind of works like a traffic cop for the system. Currently, this particular part of the system isn't perfect in our cores. Each of the three genesis cores has a slightly differing implementation for it that doesn't work well for the full library.

Sergey was in the process of rewriting this and the VDP in the 32x core, but it doesn't seems he had time to finish it yet. When that is done, perhaps then it would be possible to evaluate the various cores to see if the memory could be consolidated enough to merge some of them.

Weren't these combo games all FMVs?

Yes, we're not missing out on much.

Nope.

Yes, and most has a regular Sega CD/Mega CD counterpart.
