loooooong lurker, but eventually I had to register here as well...
Nice looking cartridge! :) But as MMC64 user, I would like to have also normal SD instead of MicroSD, so I made few searches and came up with this:

http://www.diatec.co.jp/products/det.php?prod_c=460

...which seems to solve the problem. Can someone find these available somewhere nearer to europe than Japan?

EDIT: darn, it's for MiniSD... :? oh well... it seemed nice forawhile.

Count me in for a couple.
Most micro sd card come with adaptors to standard sd so this aint
too much of a problem for me.

Wait i already said that. :)

Could you tell us more about how one would access the memory card? Would it work like an MMC64 or would it be able to handle multiple files? The thought of being able to quickly download a .d64 image to RAM and run something from the image is very exciting.

I spoke to Joe about this last night and his feeling was that it would be advantageous to call this something like Super Snapshot Pro so that he could continue to sell the original design (albeit with updated software) as the Super Snapshot (v5.whatever). They would compliment each other nicely if the original were available in the $50-$75 range and this model was in the $100-$150 range. Quite frankly though, I wouldn't flinch at paying $200 given that this seems to have most, if not all, of the functionality of a RR, an MMC64 and an RR-Net. You know, this has the potential to be the last cartridge anyone would ever want to buy. Freaky.

Very nice job, dW.


Mate i find myself in total agreeence with you this could be the last card
you need to buy.
Making this project very important to get right.

O.O! awesome...

I'm curious about the cost too, though... I mean, I only 'recently' bought my RR ( on BreakPoint ), which cost me 50 euro.. ( that's quite some money for me... >.> )

oh well, I guess I can always sell my RR for one of these babies ;_)

just wondering... will it be compatible with The Final Replay? I mean, I just hate the order of the buttons and the annoying menu with the Retro Replay ROM... >.>

If the AR6 mode fits in the CPLD (and that's a big if), TFR will also work. If you just don't like AR6, there's always native SSv5 mode.

Just a small update: the MicroSD slot is now alive and kicking. With a little optimization help from Jeri, Adrian got the SD slot mapped to the same address as the MMC64. The init code is working, and he's now reading sectors off the card.

Good news: I tested the RR-Net connected to my snappy prototype, and it works perfectly on my breadbox. The same RR-Net doesn't work when connected via my Retro Replay on the same machine (packets are received but corrupted). If you have a machine where RR-Net doesn't work (or works badly), the Snappy Gonzalez might be an option.

Why only 128k RAM? Wouldn't 512Kb or even more be alot more fun?

512K wouldn't increase the price a whole lot. The biggest limitation, however, is that cart RAM can only be accessed 8K at a time, mapped in at $8000 (just like the original SSv5 and quite similar to Retro Replay). Not impossible to work with, but still, quite painful for large amounts of data.

Might as well do a quick status update while I'm at it...

I'm working on a cart flash utility that receives the image to flash over ethernet (based on MagerValp's udpslave). About 75% done.
Also working on an AR core. Ideally, it will be selectable with a jumper, but at this point it seems unlikely they'll both fit (so we'll have to choose either SS or AR).
Prototypes have been distributed to eager Style members who will be helping out with the software side.

Short term goal is to have udpslave and ether flash functionality built-in, along with rudimentary microSD fat32(or d64) loading at WoC.

Knowing nothing about the Super Snapshot, this might be a stupid request, but:
Would it be possible to add a jumper option for configuring the cart's startup mode in such a way that it could be forced into Ultimax mode upon reset? - And additionally control the /GAME and /EXROM lines after reset?
I mean, put cart in Ultimax mode via Jumper, then execute whatever one puts in the reset vector via the ROM and then later switch to some other memory layout?
This would be a nice option for i.e. supporting a hardware debugging cartridge ROM, that would have a chance to work even if the C64 RAM was fuxx0rd.
..which reminds me, how is the RAM accessed on super snappy?

Just like AR6: it's banked in at $8000-$9fff.

ok, so /GAME and /EXROM are software configurable already.. then all that is needed is a jumper for pre-setting them to Ultimax mode.

Does it allow mapping one page of RAM into $de02/$df00 like Retro Replay does?
