FAQ: Can You Play Genesis ROMs on a Sega CD?
This question has been asked all over the Net during the last decade or so. I just encountered this topic again today and thought I would address it here.
No, there is not a way to play Genesis/Megadrive ROMs on the Sega CD. The system does not have a way to nativly play them. It also does not have the horsepower to emulate itself.
The closest thing to this was an attempt to convert Neo-Geo ROMs to Neo-Geo CD format. The project produced a couple successful conversions, but it seems to have been killed off.

Absolutely correct!
You know these flash cartridges for Mega Drive and 32X? If it could be done to flash them with a ROM from a Mega CD application….
best idea is to softmod an xbox put the emulator on there, torrent all the megadrive roms and there u have it!
every single game there was and u dont even have to open the box.
You can get a megacart from tototek.com that allows you to flash from a CD onto the cart then play.
so basically…..you just cant copy the files of a rom (lets say, sonic the hedgehog) to a CD? and be able to run it on the real SEGA CD hardware?
That’s correct — you cannot do that…
If this isn’t possible yet, it should be be. How else did Sega make the 4 in 1 and 5 in 1 discs that came with the original Sega CD and CDX respectively? If someone had access to the original source code for those titles, they could reverse engineer a loading program for other Roms. I’m betting size would be a factor however, depends on the ram and other factors. But in my mind Sega’s own publication of those discs shows it is possible to run carts of a CD.
Time travel, and objects moving at greater than speed of light are also possible. They just hadn’t been done by humans yet.
I don’t think those were emulators — they were most likely straight Genesis-to-Sega CD ports. No software to interpret the game.
so could we create a converter program to convert the genesis roms to sega cd format just take a look at sonic 1 megamix a sonic 1 hack it started of as a megadrive game then ported to sega cd
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

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