SD multicarts we desperately need


Recommended Posts

It's hard to believe we are almost 20 years into the new millennium and we still don't have SD multicarts for these very popular systems:

 

Atari 7800

Intellivision

Odyssey 2

 

So not counting flash carts? Only taking into account carts with an SD (or equivalent) type of memory card you can insert/remove?

+1 on all of these. I went looking for one for the Ody 2 and I think the most I found was a multicart of some sort. Maybe make a 7800 harmony cart? (or add 7800 compatibly to the current one?)

I have the dip switch multicart for the O2. It's a lot better than nothing but it is a pain to use.

Flash carts typically take a special program to run on your computer to interface with the flash cart. That program is usually hard to use and often won't even run on your computer without downloading special files etc and when you get a new operating system on your computer chances are it won't work at all then. SD multicarts are by far the best way to make a multicart. Just drag and drop the roms with no special programs to mess things up.

Never found flash carts any harder to use than any other multicarts, but I do get what you are saying about the ease of carts with removable memory.

 

They only reason for my question was that we do have programmable carts for the 7800 and the Intellivision, flash, SD or otherwise, as far as I know.

 

Now, working 100% or actually available to buy, that I cannot say.

This leads me into ny plea for people to open source their projects when they are done

 

Not saying making money off hard earned work is wrong but it just sucks when useful things become impossible to get due to time and lack of intrest from the original person (or worse)

LTO doesn't use SD card and doesn't show up on computer as removable drive. You need to download a program and maybe additional files to add ROMs to LTO. I didn't need to download any extra files on my laptop with Windows 10, worked the first time. But renaming files is a bit fiddy, it seems I need to select file, select rename 3 or 4 times before I could actually type something in.

 

7800 is #1 on my list to get but I am not paying eBay price for unobtanium Cuttle Cart, I'd have to wait for the SD cart whiz to sort out 7800's idiosyncrasies and make the new SD cart work on all variations of 7800.

 

I also need to get one for GBA and N64 (both currently available) and that would cover all of the cart based consoles I have.

I think most systems but the more B tier and obscure have them now. I would take a non-obscenely expensive one for the Neo-Geo and in that same vein of pricey hell same for the CD based PC Engine too being run off a SD card loaded with ISOs/ROMs. What's out there now is defective (TO) or just even higher priced and incomplete (UG2.) I know other stuff is in the works, maybe someone will get it done right.

I'll gladly buy any kind of Wonderswan flashcart. What we really need is available flashcarts of any kind for every classic console and portable.

Flashmasta made a wonderswan flash but after the early adopter red board run and 1 run of green boards theyve been silent on any further plans to build more. Im glad I got one but wish theyd make more as Ive heard from a few people that would love to buy one :/

Isn't GroovyBee's Hive cart supposed to be SD based, whenever it is ready? Or perhaps I only skimmed the details and it requires a cable to be reflashed.

 

When it comes to second tier systems, a SD card following the same principles as Rolo's multicart for the Dragon 32/CoCo probably would be the best way to go ahead. By using various cartridge adapters, he got the same multicart (using an EPROM) to also run on Vectrex, Videopac G7000/Odyssey^2, Interton VC-4000 and general APVS 1292 systems with possibly more adapters coming. Now his design uses two rotary switches and the EPROM is segmented into blocks of 8K IIRC which might not be the ideal way to treat a SD card unless you run a custom software on your PC that basically puts together an BIN image which is put on a SD card instead of burned to an EPROM, and then the cartridge reads that specific file off the SD card.

The Cuttle Cart 3 uses an sd card but it also requires a menu file. Custom software was provided to build the menu file.

 

What you want is the firmware in the cartridge to automatically scan the files and folders and build a menu. The sd card is not necessary if the cartridge presents itself as a usb mass storage class device to your computer.
