I had a "Super 2-in-1 cart" of Golden Axe and Super Shinobi (original version, pre Spider-Man copyright screen)

Cart was Japanese style, box cover was purple. Alas the cart is long gone from my collection.



You used to change which game booted up by cycling the power if my memory serves me. Always wondered how that worked, exactly...

Sure it wasn't hitting Reset? I have a pirate cart that switches games like this - I would assume this works because soft-resetting keeps some memory active that the boot ROM can use to see what game was last loaded and which to load next.

I don't think I have any multicart bootlegs. I'm pretty sure I've never come across them in the wild, and I've never actively sort them out when shopping online.

I took some pictures of my Mega Meckup. I was going to add them to the wiki but I wasn't sure how to go about doing it. Make a new page or just add them to this: http://segaretro.org...eptor_Mega_Disk

I don't know anything about it. So I'll just put them here for now: http://imgur.com/a/FUIbH

Edit: and I know this isn't a multicart, but I didn't think it needed a new topic so

Edit again: I found this advertisment, is that italian?

If it's the same thing as the Mega Disk but with different branding, add it to that page. We can work out what the best page title is later.

And yes that is Italian.

Added, thanks.

I accidenly uploaded the images to Sonic Retro instead of Sega Retro so if anyone could delete those I would appreciate it. (Mega Beckup Unit.jpg, Mega Beckup box side 2.jpg, Mega Beckup box side 1.jpg, Mega Beckup box front.jpg)
Sorry

It's even simpler than that, they use a 7474 flip-flop that changes output states when you press reset. Then, based on the output of the 7432, they just switch the ROM address lines around with some extra discrete logic (the card I have uses a 7474, two 7400s and a 7432).

That's why sometimes odd things happen if you press reset while the game is running, as the previous games data is still in RAM. You can somewhat mimic such oddities by loading game #1, making a savestate, then loading game #2 and loading the savestate from game #1.

If you do this with T2 Arcade (savestate) and Bare Knuckle 3 (the game running), you can get negative difficulty levels that have no enemies at all.

See, when you bring enough of this stuff together, you start to find patterns.

There's about 300 on Sega Retro now. If nothing else, it's probably the largest collection you'll find online.


Also image of the day:


It's like dealing drugs or something.

Holy crap that's a lot of pirate carts. Is that a private collection or a dealer?

[Black Squirrel]

I twoked the image from this auction, so I guess you can buy all this tat in one go? (or maybe £1.25-ish a piece - idk)

I can post them here or send them to you if it would actually help at all.

Nothing should go through me - both Sonic Retro and Sega Retro let users upload files for themselves. The point is to encourage more people to lend a hand because there's lots of work to do.

Indeed, this.



Maybe it's time to do another targetted scan callout again? That had some results last time.

Slightly off topic, but would you all be interested in this again? We're actually very close to having complete scan sets for US Master System, US 32X, US Sega CD and US Saturn, which would be a huge win. We're fairly close on EU Dreamcast too.

Ratigators has complete USA manuals and for all Sega machines (and for many of them covers too), since you guys just grab stuff from anywhere you could include those.

Is this the right topic for this?

Lego Batman for the Sega Mega Drive:

It's Russian.

EDIT: What happened to this? I doubt you simply deleted it without putting it with something else.

Mega Drive bootleg games - I moved it away from the User: namespace. There probably needs to be a better way to handle it all - there's still hundreds that aren't documented.
