Yeah. This could require a lil' Arduino or PIC type of circuit which would read the SRAM and put the data out a USB port.

Excellent challenge KeFF, so creative! Updating the front page now.

That's so cool! I wonder though, will MuteCity be able to make these just by modifying original Nintendo hardware? (another not so subtle poke) From the little I know from Neil, this could be a real challenge to make dedicated cartridges, since carts with an adequate configuration were never produced for the US market. wink It's either a load of soldering or a ReproPak from retroUSB. But I am itching for a little challenge here.

Mmm, so excellent. Another use for the ever-versatile NROM cartridge! I dunno if I'll ever get a chance to meet you in person, but it'd be a real honor.

OH, and my big thanks goes to you for making this Open Source! Alot of people here can't imagine how awesome this is that it's all GPL, and as a hardcore GPL junkie for several years I thank you most heartily for the source code so generously provided. If only all the other awesome tools for the chipscene were GPL, like LSDJ or NanoLoop, this place would really be busting at the scenes.

Sounds like a good plan to me. R&D is a big part of why I mess with this stuff, actually.

Nice job Keff. I go on hiatus for a day or two to get my computer fixed, and come back to this. Awesome. Now you should challenge someone else Keff!

Nice work Neil. I look forward to making a cartridge of this very very much. In fact, if you don't mind sending me an advance copy (PM me to get my email) I can get working on it sooner. *blatant hint*

Aaaand... I think it's time for a submission man!

Yeah, no purple? This could be quite cool, actually. Especially considering that... well, no offense, that palette is a pretty steep limitation.

I am going to build my own... smile
It's not going to be anything spectacular, but it could be kinda neat...

Indeed! Mr. Tirstendo, please pick the next challenger. If you don't do it soon we'll have to do it for you, so this doesn't get killed off.

Hmm, guess it's time for a lil update here. Nice work Tristendo!

However, the Repropak boards do offer a little more flexibility with this, and are certainly alot easier to get set up than hacking an existing MMC1 board.

Ultimately, we'll just have to wait and see what his finished ROM looks like. And as for an SRAM save/load to PC circuit, that could certainly be done, though I'm probably not going to attempt that one myself.

Without using MMC1 (or any mapper), what are the options? If a non-mapper cart is limited to 32kb PRG then it's never going to happen - the editor itself take about that much space! smile

You are indeed correct. MMC1 is a good choice because it's common and simple. I applaud your selection, actually, its just that without seeing the ROM I'm not completely sure what specific board configuration to use.

Yes, orgwell has it about right. When I need long battery life in my devices, especially my Tandy 102, I go with plain old alkaline AA batteries.

Wow! Nice work. I like your heart design, it's quite genius.
