@Ben Hartland only partially correct imho. you'd still need a flashcart loaded into the main deck, but there's no reason it shouldn't work. though...why even bother going through all that trouble if at this stage of console hacking you could just build a flashcart that can load a 32gb SDHC card and run faster than a cd? or two or more, considering their size in relation to a genesis cart. let's not forget the little issue of GAMESAVES. personally given all the trouble that'd take i'd just run it off an xbox or wii emulator, and work on making one of these bad boys work on the given system.

It can be done, but its not a simple conversion. Sonic 1 megamix was ported by rewriting a lot of the assembly and using Sonic CD assembly as a comparison. Other games won’t be as straight forward. But still, you guys are all right, it should have been done by now. In terms of hardware, it still utilises the original processor, does it not? It could be as simple as writing a boot loader that allows you to select a ROM from the CD, and pushing it into the Genesis processor. I could be completely wrong though, I don’t know if it uses that processor at all, but I think it does, otherwise why have it as an add-on?

I actually stumbled on this after playing Sonic 1 Megamix and searching for anything on converting genesis roms to Sega CD in some way… the obvious and HUGE deal would be that the Sega CD had no copy protection, so you could play any Genesis roms on the REAL system! There HAS to be a way to do this!

Once I get my hands on a Model 2, I’ll buy Sonic CD and burn Sonic 1 Megamix to a CD-R.

Speaking of Sonic 1 Megamix, I just downloaded the new ISO of the completed project and burned it to cd. It works perfectly fine on a real Sega CD. Team Megamix must know how to do it if they just did with their project.

Hi,
we managed to did this for the pc engine. Thanks to the internal ram provided by the cd system, we could load a patched rom in it to run it (it is patched because it is executed from bank 0×68 and not bank 0×00 occupied by the cd system itself). It can only run games of 1 mbits maximum and only when we managed to patch it correctly (which is not an easy task).
You can see the project there : http://www.zeograd.com/super_hucard_download.php

regards,
