I even mentioned that earlier in the thread: viewtopic.php?p=98828#p98828

I can't test this, and I'm not certain which games care, but try adding a large resistor (100k, give or take?) from CIC socket pin 6 to CIC socket pin 10.

If it doesn't work, we'll need a more complicated circuit to make sure that any unlicensed games that use a CIC stunner won't blow everything up.

so did nintendo break that on the top loader? that would be a cool mod/fix for top loaders.. i don't own that cart (or maybe i do) not a big sports fan.. :lol:

should be able to recycle the diode and other parts to protect the inverter chip on my circuit.. they are used to protect the input of the CIC by shorting out the -5v spikes normally found in rare third party and pirate carts :)

As far as I know (and Nestopia's source loosely corroborates), only mappers 37 (SMB/Tetris/NWC) and 47 (SSVBall/NWC) use CIC RESET to reset a multicart. And the former, being Europe-only, I think wasn't even in a place with toploaders (No toploader was released in PAL regions, right?) Adding whatever simple circuit for this seems awkward for just one game (unless, of course, it's your console :))

That and the other (far less common) game with NWC as the initials.

does the pirate version retrousb sells work the same way? or is that unaffected?

Given that he says it works on toploaders, "asian systems", and only doesn't work on the famicom for the lack of a 2nd player start, I bet it doesn't.

Yeah, the NWC repro derives reset some other way, probably the same way as the PowerPak.

So, just added an 100k resistor between Pin6&10, now my Pal B SMB+Tetris+NWS works !

Thanks ;)

Hi,

Can you show a photo to describe it ?

Thx

how did brian get permission to repro nintendo games? :? or do you think nintendo is sitting on their hands until he ends up like the "super joy guy" who got five years in federal prison.. i'm not worried about the JCIC project because of the terms to download it.. i was thinking of releasing VS. cart with a ribbon cable so the ROMs could plugin on-top of the nes.. like a converter :)

NESler, you mean 6 and 10, right? Otherwise I'm confused what's going on.
edit: he changed his post

wow :lol: right 10 is the reset line for the carts mapper/cic
good thing it's a 100k!.. that would connect two outputs together.. post edited above to remove quote!.. ;)

I think it's a safe bet to guess he doesn't have permission to repro anything besides the homebrews... My guess is Nintendo doesn't think he's worth the money required to go after him, either that or they are somehow unaware of his titles. Interesting story about the super joy, I guess it shows that Nintendo really does still care enough to take action. But it sounds like the super joy itself was the big fish worth frying, not that guy alone.

Edit: it might also be worth noting that Nintendo's financials have been on a downward trend since 2008 and they're bleeding pretty bad right now. So I think it's safe to say they have bigger matters of concern than His NWC carts. They don't put much of a dent on their 100's of millions of dollars in annual losses currently. It may be a different story if Nintendo rebounds with the Wii U though and they're looking spend money in attempt to teach anti-pirating lessons...

Or the other option: With what he does he has information of how the hardware works, bug fixes, etc. that Nintendo could find useful.

ETA: Nintendo is not turning a profit? Says who? They don't hold a candle to any other system ATM in terms of profit from who I see buying games today, but still...losing money? Hmmm...
