PR8 / Pulsar, the reason it has so many steps is because PR8 runs on a hardware setup only found in a total of 2 games across the entire famicom and NES library, so he goes about hacking the hardware into an existing easier to find board instead of hunting a donor down. You can find a suitable donor (Final Fantasy 1+2 for famicom) reasonably cheap, shipping always kills the deal though, so you're almost guaranteed to be paying atleast 8-10$ for the cart

NTRQ - Interesting. I'll check this out tomorrow.

PR8/Pulsar - I understand why there are so many steps. If you managed to follow the thread (lengthy!) you would see that I tested the build with a friend of mine and the build used for a Famicom donor doesn't work on the American NES w/ an American donor. My question is why doesn't it work for the NES when it works for the Famicom?

what donor did you use?

I assume someone traced the SXROM board to see if it uses every pin on the cart header, NES-SNROM pcb's don't always have every pin on the board. It's the same issue that affects building FF3 repros since the only suitable US donor is a copy of Super Mario Bros 2 that happens to have every pin intact (alot of copies dont).otherwise you have to manually re-add a pin to the cart header which isn't very reiiable. Maybe (probably) SXROM is using one of those additional pins and it needs to be reconnected

Top of my head without knowing which carts were used, I would think thats a possible culprit. I haven't read the thread.

Sort of off topic, but could someone explain to me what makes this cart work, opposed to the method described here:

This has been punching my brain for the better half of six months now. We're close, but not quite there.

Sweet. If you want to make a cottage industry of it, you could convert this thread after the fact to a per-order NTRQ cart thing.

Also, do you make these with donor boards, or from new parts? I don't know enough about NES repro stuff to be sure, but I'm under the impression you can make an NTRQ cart from all new parts out of stuff you can get from Digi-Key and RetroUSB.

EDIT: Oh shit, you can even use this thing to make Pulsar or PR8 carts. Damn, I hope they restock that thing!

I'm not really sure if retrozone's mmc1 board can be used to do SNROM or not to be honest, it's easier to just use donors

How are/were these made, anyway? Was this a production run or homemade?

I can't find the guide for building them anywhere anymore, but I know I've read it before. sad

the guide I saw online actually has an extra wire routed in, I generally follow http://nesdev.com/NES%20EPROM%20Conversions.txt for wiring

AFAIK all ntrq carts are either self made or were produced in a batch by a 3rd party, I don't think neil has ever done a first hand run of them.

this cart is running NTRQ 1.8 btw

I have a spare NTRQ cart for sale, $40 shipped in the US. A portion of the sale will go towards Neil's cancer donation fund. Will ship internationally if you ask.

Cart label is based off Thretris' design
