Hello all!

I'm relatively new to copiers and the like, and recently came into possession of a Double Pro Fighter X (Genesis/SNES). When I picked it up, the seller included this cartridge as an extra. I'm primarily a Genesis collector (the only Nintendo console I ever owned was the N64), and the seller didn't really know what any of this stuff was, so I'm looking to see if anyone here can help me figure out what it is:

My best guess is it's a programmable super famicom flash cart? I used the google translate app to try to read the labels, but it's not super clear (see the last picture in the above gallery). I would have opened it to take pics of the board, but I wasn't sure how to get it apart; it doesn't seem to have any screws, not even under the stickers.

Any help would be greatly appreciated. Thank you!

You have opened this cartridge? Have you tested on the snes?
Thank you

So I managed to get it open without breaking it, and I added pictures of the CB to the gallery above. The datasheet I found for its one chip (link) says it's a 4Mbit CMOS EPROM, but the description beneath says it's "One Time Programmable Read Only Memory"; I thought EPROM meant re-programmable? So I'm not sure if it's a reusable flash cart, or just a pre-programmed pirate cart.

I don't actually own a SNES/famicom (I'm a Sega-only collector), so I can't actually try it at the moment. I'll see if I can pick one up at some point. On a side note, are famicom carts compatible with the US SNES? or are they region locked or something? I don't actually know much about the system.

Nice one, I've been looking for this cartridge for a while.
Did you buy it in Asia?

To answer your question, it's a similar "fake memory upgrade" to the 4M SF2 Turbo. I wasn't sure till you opened the case, so thanks for that.

The 4M SF2 Turbo cartridge was made back when the game was released and most copiers on the market were 16Mb, while SF2 Turbo was 20Mb.
Memory was very expensive at the time following the fire of one major producer of those ICs in Japan (I posted that doc somewhere on ths forum)

To get ahead of the competition, CCL released that cart as a memory upgrade while it was in fact just an eprom with the last 4Mb of the original SF2 Turbo game. Clever but totally misleading and illegal since it was using Capcom copyrighted material.

Your cartridge seems to do exactly the same thing with the addition of an unpopulated 4Mb eprom.
More than likely it was released at a time when most copiers sold were 24Mb and one popular game came out using an extra 2Mb or 4Mb. There are not many games like that so I'll have a look and check.
You can easily dump it on your copier and attach the link so we can have a look at it to match it with an existing game. It should show up on your pro fighter as a 4Mb cartridge.

Thank you for the detailed description! Very interesting history if correct.

No I didn't personally buy it there, but given the labels I'm sure that's where it originally came from. I bought a Double Pro Fighter X (pics) a little while ago, and the seller included this cartridge as an extra. He wouldn't say where any of it came from, nor did he seem to know much about either the DPFX or the cart. I'm guessing he found it at a thrift store or garage sale somewhere, but we'll never know for sure.

I don't actually have a SNES at the moment to be able to dump it, so that will have to be some time in the future.

Nice DPFX, it's in pristine condition. The 64M sticker indicates it's upgradeable to 64M but I believe the ram board is just a standard 32M max one.

check page 3 and 4 of this thread for the story of the SF2 Turbo cart:

If you have a chance to dump your cart, you can update this thread, I'll receive a notification Wink

Thanks, I spent a lot of time restoring it. You're right that the RAM board is a 32mb, but looking at it only half of the board is populated (pic), which makes me wonder if it could be upgraded to 64mb... not that I'd try though, really I got it more for a collector's piece/display than practical use.

Very interesting read, though I don't really see anywhere it mentioning fakes of the memory upgrades. Either way, I'll take your word for it, and I'll try to grab a SNES to test/dump this cart.

This is the standard DPF memory board, it's maxed out at 32M, those unpopulated slots are for different memory packages

Of course it's not mentioned, CCL was tricking its customers into selling RAM extension that was supposed to be reusable with different games. This kind of cart doesn't show up often so as kyuusaku assumed in that thread back then, it was believed to be RAM with some address decoding.
Only when I opened mine and dumped it I realized it was just a cheap ROM

Ah I see I misunderstood, I didn't realize that memo was from CCL themselves (of course it wouldn't say so, then Rolling Eyes)
