4 meg Ram modification???

[Michael Knight]

Hi! It´s been a long time since I write something here ... anyway, I think I have something interesting here ...

Well, as the topic says, I have a 4 meg cart for saturn (It was made by EMS industries, in Honk Kong), you have a photo of what it looks like

Ok, so I was curious to know what the cart had inside, so I opened it and founded this ...

Well, the first think I saw was that they were 3 sockets without nothing on them, (32 pins X 2, 10 pins X1)

Anyway, I looked the back side of the circuit and I founded something I saw sometime ago in NCSX´s site (if anyone remember, my cart has been modded, it has the Vampire Saviour fix (you know, cut & solder 1 wire) ..... so I thought "Well, this mod was for AR cartrigdes ...... so... " ..

So, does this mean I have an AR cart (well those 2 32 pins sockets without nothing soldered .... it could mean that in any of those sockets, the AR bios must be soldered????

Anyone with an 4meg AR can open it, take a photo and compare ......or if anyone has a working dump of the AR bios and knows if it can be recorded into an Eprom or something similiar??????

Anyone knows anything??

I've just scanned my AR4MB+ but I've got nowhere to host the pic. Do you want me to email it to you?

 

[CHE]

I have the same cart too... but it executes all games without modify it at all. I can take pics and send them to you by mail too... if you need them.

 

[Michael Knight]

CHE & mal, please, email those pics to me

Thanks!!

 

[CHE]

Here is the cart... image quality is low, because the poor ilumination, but enough to see the differences

 

[mal]

Umm, CHE I think he was after a pic from an AR cart.

Isn't yours the same as his? (minus the electrolytic cap anyway)

 

[CHE]

Wha ha ha ha !! yes... what a mistake !!

 

[Michael Knight]

Well, CHE, I think we have the same cartrigde

, anyway, thanks for your cooperation

Mal, send me the pics you have made to my e-mail, please!!

---------------------------------------------

I have checked the miscellaneous section of this site, and I have founded the commslink utilities, so I downloaded the file, extracted it, and to my surprise I found a bin file "AR.bin", well, 3 .bin files exactly so if my theory is right ... if I burn "AR.bin" in an 32 pins eprom or flashrom and solder it to the my 4 meg cart, maybe it will work .......

I will try as soon as I talk with a friend that has one of those eprom programmers ...

 

[mal]

I'll email it to you when I get your address.
