sram !!!

[Thelen]

finally it's working.... my sram cart programmer for 4K games. My device can read out normal game cartridges and dump them to a .BIN file and i can program my cart with the 4K sram on it with every 4K game i want.

after 2 failing projects it's working !!!!.

 

But i want to know how the bankswitching principe is working, could anyone tell me ??

 

ThankS , THELEN

Nice Job

 

You'll may find more infos about bankswitching here : http://tripoint.org/kevtris/files/sizes.txt

 

Any possibility to know more about you sram cart ?

How does it work ?

Do you use this cart with the modified 7800 (Eckhard DevOs ) ?

Can I get the schematics/driver software from you? I have built my own, but I never got it to work. I plan to build a new one, but I want to get a good set of actual tested schematics. Thanks!

well first i have to draw the scematics on the pc and make the software some more user friendly. it will take some days. i will post a message when it's ready.

 

it's a stand alone device which is connected to the parallel port.you can put your sram cart in it(and program it with a game) or just a normal game-cartride to readout and save to a .bin name you specify

 

you can build it with just 4 easy ic's ,a counter(4040) shift register(4021) inverter(7404) and you must have a sram ic.(i use a 32K => 62256 from an old 486)

 

but first i'm drawing the scematics and software, then you'll hear it.
