View Full Version : "Memory Card" for the Genesis?

I just thought of what could have been the best thing ever to my childhood gaming experience- A "game save" cart for games that did not offer in-game saving. Think of how awesome it would have been to "save" your progress on Sonic 2.

Since the Genesis lacked any internal memory, it would have to be an add-on device, inserted first into the cartridge slot, then attach your game to it something like the Game Genie or S&K in design. Play your game, and SAVE it. Come back later where you left off. The device would have a user menu to select your game before you start.

Memory amounts back in like 1993, would be like 32 megs? Enough to save several dozen game files?

There are so many games out there that i never beat, because it took hours of game play.

Do you think something like this would have sold? If so, why or why not?

They made this for the Snes back in the day, pretty much a save state cartridge.
I once saw one on eBay but was outbid.

It could be an interesting homebrew project, but the biggest issue is the demand. Would enough people be interested in buying such a device?

I'd buy it.

I think that the lock on cart should use fram so it needs no battery here is some 4megabit or 512kb fram that is accessed in words like the genesis instead of bytes so the data does not need to be odd aligned. http://edevice.fujitsu.com/cgi-bin/document/document_search.cgi?LANG=EN&PARTNO=MB85R4002A&DOCTYPE=D02
unfortunately 3.3v
or here is some 8megabit (1megabyte) fram http://www.ramtron.com/products/nonvolatile-memory/parallel-product.aspx?id=116 and again 3.3v but either way this is better because it would need no battery which sram does so it would reduce cost.

Problem is that SRAM + battery is magnitudes cheaper than FeRAM

I remember seeing one of these advertised for NES.

An alternative which Sega could have offered is an add-on like the Tennokoe Bank II/Turbo Booster Plus for PC Engine/TurboGrafx-16.

That doesn't make any sense at all. The Booster Plus works because the HuCard games were designed to work with it, using that expansion port! The TGCD offers the same capability. There's no way an EXT or SCD Expansion Port saving module would work, every game would have to be re-configured to work with it. The only method that would work is a cartridge add-on, like the previously mentioned Naki Game Saver+. Here's a couple pictures:

Can't you use a flash cart with a save state function?

You do know most people here own original cartridges, not flash carts... Right?

Neither do I.

Emulator style save states are quite impossible, and making games not designed to save to save is not exaclty easy either.

Then what does this thing do? looks like a save state to me.

Man if I had a thing like that I would have modded it so it took power from the wallsocket.

I'm not seeing how they can restore all hardware registers and such, unless they got some extensive spy circuits in them that sniff the whole system... which gets hard on MD because of 2 CPUs which of one is not directly visible, plus YM which is more or less write only device.
I would love to see inside that thing

I remember that the Super Wildcard DXII could also do savestates like that, never did try it though. (though I saw a friend of mine do it with SF2 once)
