Will it be available only as a board, or also available populated?

If the latter: How will the populated version be reprogrammed? Will there be an option for an SPDT mirroring switch? And will you provide all three options for lockout defeat (none for pin 4 cut and toploaders, desoldered original CIC chip, and Camerica defeat)?

Is it just UNROM (1 Mbit) or also UOROM (2 Mbit)?

The link is broken for the pic, and I'm curious to see it!

Members: You certainly got my attention! :) Thanks for offering to make this available somehow.

As for more info, I think I speak for everyone in this thread when I say: don't wait, fire away.

PS, I would hope we can get those at least partially populated as soldering SMC's is not always a workable situation.

You can use CopyNES to rewrite this cart, if it's built in the Flash configuration. But you need to install one wire between the CopyNES board and the NES mainboard, this feature is on CopyNES but it hasn't been used before. It uses one of the otherwise-unused expansion pins of the cart. A rewritten cart will play on a normal NES also.

PRG-ROM sizes supported: 32kB, 64kB, 128kB, or 256kB
PRG-ROM page size: 2 modes (hard-wired). 16kB pages (with upper 16kB fixed), or 32kB pages.
CHR-RAM size: 8kB
Nametable mirroring: Standard 2-screen for H or V. Hard-wired.
PRG Memory type: 28 or 32-pin EPROM, or 32-pin FlashROM.

It will be available as a bare board, and built (fully or partially). Supply artwork and I can make some good-looking labeled carts too.

tepples: I could solder a switch on there, but it would just be hanging by 3 wires because I wouldn't know where to mount it exactly.

I didn't use any lockout defeats, since it would be experimental and for now I want something that's simple and just works. I'd use some kind of defeater if I could get new cart cases.

no carrier: That's odd. I've got the pic here also. http://memblers.home.comcast.net/Pic204a.jpg

Any other way to do it that doesn't involve buying a CopyNES? Or is it just expected that all people who want to become involved in NES development will have to save up for a CopyNES?

Price?
tepples: I could solder a switch on there, but it would just be hanging by 3 wires because I wouldn't know where to mount it exactly.
Could the mirroring switch be glued onto one of the flat parts of the board that doesn't have any parts and then connected by 3 wires?

"Cut pin 4 for now." Check.

Looks nice and optimized. I bet it can be panelized easily, for low cost production.

I should mention that I believe (based on what Memblers has stated about the usage of pins of this cart in a different thread) that my CopyCart NES dumper will be able to re-program this thing. I've been slacking on the development of this thing, but I am planning on ordering 3 PCB prototypes "soon".

Thanks, tepples.
Wow, you're getting professional circuit design, with red case, and surfacemount componnants, for your garage carts ? That's cool !

Yes, I'm working on the new 'Membler Industries' site. I need to design and print some cartridge labels, and take some better pictures, but other than that, these things are ready to go.
