Got the 7725 core cranked up to 19.2MHz... now what to do with it ^^;
F1 ROC displays one line of garbage in the upper half of the screen now, everything else still works perfectly. There was no real point in doing it, though. But that will give me enough additional headroom for the opcode LUT handling in case I decide to implement ST0011...

What is it exactly that the OBC1 does, and for what purpose? From skipping through bsnes source it looked like it just shuffles some addresses around when cart RAM is accessed, based on register settings.

The OBC1 is just a glorified bit twiddler used for building OAM (sprite) tables. Each sprite has 34-bits of data, and the last two bits can be a pain to access for individual sprites, because they are all packed into a separate buffer.

It seems like an absolute waste of money, some better code optimizations would most certainly allow Metal Combat to work with only the base hardware.

Assuming the cost is under $500, sign me up for one. I am most interested in the DSP emulation. It is nice to see somebody finally creating a SNES flash cart that won't require destroying retro-gaming hardware.

Are you going to get a nice plastic shell designed and fabricated for sd2snes? If you are mainly interested in designing the perfect technology and don't want to be overly troubled with business stuff, consider teaming up with RetroZone. While they already sell the SNES PowerPak, they could sell a product based on your sd2snes as a higher-end alternative to the PowerPak.

To whom it may concern: I put up a little blog documenting the current status and progress :)

You implemented CX4 core in your cart design? That's awesome! Wasn't expecting that kind of thing. As far as I know that's something no other commercial flash cart maker ever implemented. My god, last time I checked on this project long time ago I just thought it would end up just being a fun project for you duplicating the basic functionality of an everdrive or powerpak. I just say the list of core you implemented and the one planned. All I have to say is Wow. Keep going like that and I reckon you will be creating some serious buzz and interest among the retro gaming community. I wasn't excited about a SNES flash cart in a while but that seriously did the trick.

I'm running a batch of 100pcs in the course of 2012, starting end of March. The hardware is now declared final :)
Most units are already reserved but there's still a small quantity left. If you're interested drop me a private message here or via http://sd2snes.de/blog/contact .
EUR 120 + shipping (depending on country of destination). It ships as an assembled PCB in an ESD bag, bubblewrapped, in a cardboard box.

Be prepared to wait though - I'll be making this batch by hand so I can only make ~3pcs per week ;)

And that's it - all are gone. :)
Everybody who wrote me has made it on the list, even though I haven't replied to all messages yet. I hope to answer all messages within the next two days.

Looks like I missed out, Bummer.

Oh well. Stuck with BSNES for now.

ikari, was there any chance of you "licensing" the design for other larger operations to make?

Looks like StoneAgeGamer is organizing a proper mass production, which is good because ikari's time is better spent improving the firmware:

Hopefully everybody plays fair and money from sales is fairly distributed.

It will be Krikzz, Mr. Everdrive, handling the production, he just posted that on his forum! Will be the "Ferrari" $$$ of SNES flash carts though.

When this us mass produced I will likely choose is over a powerpak. I love my nes powerpak but this is much more advanced than the snes version.

Supposedly the price is going to be like $170 though. Honestly, that is just ridiculous.

Actually I think $170 is a good price. I was afraid with all its features and abilities that it would be more than that. The snes powerpak is $155, $140 at the moment on sale, and can't do all this one can. I'm pleased with $170 if that is the final price.
