Expanding Gameboy Cart SRAM

It's not that hard actually..

I found a chip on digikey, ISSI IS62C256AL-45ULI, $2 - I was able to solder every single pin to the same spot on the cart except for 1 pin, and then connect the new address lines to the memory mapper.. (MBC1-MBC5)

Here is the process I performed in expanding my Kirby's Dreamland 2 Flash cart from its normal 8KB RAM to an added 32KB RAM.........

Ok here's the old Cart loook

FAIL... then hope.

Well I was bending the pins to make it easier to solder...
But the TSOP pins are soo effiinn weak... I already lost 2 of them just because the wires were moving after I soldered them!! so I said fack, the -90SD chip is hard to find... 

But then I found this on the web..
I can totally make a pcb like this and order another TSOP!! WOOT I just got to figure out how to design the pcb.. I've never used the software and such...

Pokemon Pinball flashcart is not over with yet!!!

And So It Begins...

I said ;fack; cause the f032b is much wider than the MX chip.. First I thought I would have to solder wires to the pads!! heLL NO... but there's plenty of traces and I'm using almost all of them!! 4 more wires to trace and then we can trim teh wires and get the bad boy Flash chip hooked up.. 


Q:... I added the RAM chip to PokeMon Pinball for 32 KB RAM. 2 more address lines.. Do I need to connect these address lines from the flash rom to the RAM?? I am guessing YES.?>?
A:????

Q:Also, there was 2 CE lines in the old ram chip, only one on the new one.. is this neglectable?
A: Bridge the old CE to the new 1..

TO-DO

PokeMON Pinball Cart Mod--
1) Map pins from MX ROM chip to AMD Flash chip..

2) Figure out what to do with address line going to Rumble feature.. leave battery out? make switch between extra rom / rumble??' Actually, looking at my cart, it looks like I'll only be using AA13+14, leavingg 15+16 unused and rumble feature intact :]

3) Adding RAM
this will be the easiest part.. practically a drop-in!! :D


For my SNES Gear...
ATMEGA LPT->USB
1) Create Prototype on perf board / PCB breadboard....
2) Test in WINDOWS.. figure out flashing of ATMEGA..
