Found this cool project that people might be interested in ie putting roms onto a modified SMS cart to play on your original hardware

http://www.smspower.org/smsreader/


It plugs into your PC's parallel port (which must operate in bi-directional mode), and is controlled by software running under Windows or MS-DOS. Using the reader, you can:

* Read your own Sega cartridges and copy the ROM images onto your hard drive, so you can use them in emulators such as Meka.
* Write ROM images onto specially modified cartridges with battery backed RAM, so you can use them on the real Master System.
* Read and write your saved games from cartridges like Phantasy Star, which have battery backed RAM for save positions.

I just read the same question on a forum... and was linked to ToToTek.
Looks like there are all sorts of flash carts here:

Here's a homemade reprogrammable MD cart:

Did a quick check for buying parts in my Jaycar catalogue.
Most are cheap parts ie under $1.
Hardest to come by will be inline resistor (tho can just replace with normal resistors) and the edge connector. Not sure where to get one of them (other than hacking open an SMS)

Could you use an old ISA slot of an old mother board?

It might need some hacking to size :unsure

As long as the contacts line up it would be possible... hmm

And here are the mods in my SMS you need to get full value out of having a re-writable SMS cart:

http://tehkella.net/damian/Consoles/SMSModsFM.jpg

50/60Hz Mod
Region Change Mod
FM Sound Mod

The 3 wires in a row next to the marking "JP2" are for the 50/60Hz mod
The wire coming off the 315-5237 chip to a switch with ground connection is for the region change
The unit plugged into the expansion port with a wire coming off it is the FM sound unit

Not all SMS model ones are the same, there is plenty of info available on the net though.

I'll gradually work on the Cart Reader/ Writer device amongst other things........

Yessir, for my birthday (March 2007) I got both Master System and SNES reflashable carts from Tototek courtesy of my missus.

Want to know the tragic part? I haven't even used them once yet. No goddamn time to even get that much done. :(

I have finished making the SMS Cart Reader/ writer now. I have read some carts with it and it works fine. I need to get some parts online to make a re-writable cartridge next.

I received RAM chips from Futurlec for the re-writable cartridge. There is a problem though, they didn't send me the exact same chip as I ordered. Can anybody here tell me what the difference is between the chips, and if the one they sent me might be a suitable alternative?

I ordered Hitachi 628128 RAM chips as per this datasheet (http://www.futurlec.com/Memory/628128.shtml)

They sent me Wingshing 628128LLP-70 RAM chips as per this datasheet (http://www.futurlec.com/Memory/628128LLP-70.shtml)

I am not sure what to look for to determine if what they sent me will work just as well anyway? Can anybody offer advice, I am not up to speed with this stuff yet.

It's been a while since you posted this. They are functionally (and pin) identical. The part you received is a 70ns access time chip, so if that is the same or less than the project specifies, you'll be fine.

Even though by now you've probably built it and found out for yourself :)

Cheers

I am about half way through making the cart with those chips, hopefully will finish it this weekend. Thanks for the advice about the chips!

How'd you go mate? Get it all done?

@ Elvis; Have you tried the SNES flash cart from ToToTEK yet?

Nope, been too busy.

No pressing appointments this weekend. If I get all the repairs around the house done I want to do, I'll give it a whirl.

Cool, lemmie know. I might get one down the track.
I'm getting my rom packages sorted for my Xbox, but I'd love to play the SNES stuff on original hardware :)

ah well I got it made, but it didn't work. I went over everything, no shorts, all connections had continuity that should have, all voltages were as expected, I really don't know why it didn't work. Maybe one of the RAM chips was dead?

Bugger. So where to from here? Give up?

How does the T-connector PCB and the CIC-161 chip work that Tototek sell?
