2 questions about SD cards

[Impmon]

Someone (not me) is working to make a special cxartridge that can be used
with MMC card to load any 2600 game ROM for playing on the actual 2600
system. It could prove useful to game development as it'd skip the need to
burn EPROM and eliminate the need to build custom cart PCB for games larger
then 4K.

But MMC is fairly hard to find locally nowday and pretty much all
electronics uses SD instead of MMC. Even those that uses MMC can use SD.

So my question is: does anyone know where I could find a detailed spec on SD
card including how to read it and such? Also where may I find a source of
SD card socket? I could be wrong but it appears to be slightly different
than MMC card socket. Finding the info and the socket could help get the
cart to use SD card instead of MMC card (or even use both)

Thanks.

Why not just use EEPROM, or battery backed ram to store the code for
testing? Also, the April 1986 issue of BYTE magazine had a project for
an in circuit EPROM emulator. "Build the Emulo-8" starts on page 105. It
has a serial interface, but that could be changed to a parallel, USB, or
ethernet port with modern chipsets.

You mean Atari 2600?

Sean Kelly makes a Multi Cart, has the entire library on one cartridge, as well as custom
games. Check out atari newsgroups, as well as Vectrex and ask for Sean Kelly.

I have a Vectrex Multi Cart for my Vectrex, amazing.

Has the entire library on one cart available through menu control.

I know about Sean Kelly multicart but currently he only sells Vectrex
version. (copyright issue) And that's not what I'm looking because
multicart couldn't updated by self for new games or to test a new program.

EPROM is also out of question, most people don't have EPROM programmer and
don't want to build or own one.

The MMC card based cart is currently under development as most people
already has the multicard reader or could get one for under $15 and new
games can be added in a blink.
