Play Genesis roms on your sega cd?

I was reading about this on the Magic Engine forum:

I haven't tried it but evidently you can hack the 4-in-1 turbo grafx iso to play any hucard game if you burn the rom to a cd-r.


I wonder if this would work for the sega cd if you used the sega classics compilation that had streets of rage, revenge of shinobi, and columns? I'm guessing that these games were, in fact, roms and were not being emulated but played using the genesis hardware.

Well you would need some sort of a rom loader for the genny roms that would load on a sega cd. I don't see anyone programming that any time soon.

As far as I know, the Genesis one doesn't just use straight dumps of the ROMs. You'll notice that certain games have multiple loads, since they wouldn't fit entirely into the Sega CD's RAM.

I forgot about that part of the equation.

This idea has been discusses countless times in sega forums

ANd its impossible to do. There are sevearl problems

(I hope you understand, im not very hardware proficient)

The sega cd has 6 mbits of ram only, and most games wouldnt fit there. THeyd need to be reprogrammed and split.

Some internal memory stuff (like dmas) change when the sega cd boots up , and those memory addresses are different than when the genesis boots by itself only. That makes it impossible too

For the time being, i`d recommend you get a nomad, or PSP genesis

I thought the Sega CD has 768K of Ram which is almost 3 times as much as the tg16 with a 3.0 card. Are most Genesis games more than 768K? I'm sure the later games like Phantasy Star 4 were big but what about the first generation games?

768KB = 6 megabits. And some of that memory is used for other buffers IIRC.

Most genesis games are over 8 megabits. Even if the sega cd had loads of ram, the memory mapping when booting a cd game is completely different than when booting up a cartridge.

What about the Sega Dreamcast, which featured the Sega Smashpack collection? Genny games are emulated, but with very, very poor sound emulation resulting.

If I'm not mistaken, that's been done already. But like you said, the emulation kinda sucks, so nobody really cares. ;-)

A pirate group did hack the code for the smash pack so you could load a separate disc of genny roms. It worked ok at best, a lot of the titles where glitchy.

It's strange that the DC has such an easy time handling games like Soul Calibur, yet has difficulty getting 16 bit games to emulate with sound that is at least 90% accurate. If the emulator was designed by hackers (as are most PC emulators), then I'd understand the poor performance, given the fact that the time put into programming the emulator would not be financially compensated. But why, I ask, couldn't Sega's own team of programmers make a decent emulator for a commercial product?!?
