Well if I get it correctly, if you want to use a 256k SRAM and use it as 64k, why don't you just simply connect A13 & A14 straight to GND??

Yes but what's the point of doing it all over again if there is an existing project somewhere (if there are gerber files, it must be), but who has that??

So is there any editable project of that PCB?? If yes, can anybody share it??

Hey, I started messing around the program called FreePCB yesterday since I want to design a prototype board for myself by modifying the existing project from here: http://www.retrohacker.info/pcb-cads/WillemSNESAdapter.zip So first of all- how to import the damn things into the program??? I tried ev...

So... after all will it be good for SNES or not??

Alright, I have 1 more question- will these 2 memories be capable of running SNES games??
-AM29F016B-90EC
-AM29F016D-90EC

What do "B" and "D" mean after "016"?? Thanks in advance!!

Hey there folks once again!! I need your help I have an original Tales of Phantasia cart and want to program the translated version of it into this cartridge. So first of all I need a 29F016+29F032 memories and TSOP adapters but how do I have to program them?? Do I need to solder 29F016 into the 1st...

Alright, I get it. So I can easily buy those 75 and they will be compatible with every game?? Also, which one is better, 75EC or 75EI or there's no much difference between them??

Alright, so here I can buy these ones. Which one is better??

AM29F032B-75EI
AM29F032B-75EC

Also, I noticed that slower (exactly 120ns) memories are more expensive.... why??

That's unbelievable how something complicated as F^&#* (or at least it seemed to be) turns out to be so easy as pie.... When you published your response, not only you gave me some very useful information but I have even already bought the PCBs!! I'm just stunned how simple that site is!! Well fi...

Adapter: http://retrohacker.info/viewtopic.php?f=15&t=3 Thanks so much for the information, that sure will help a lot!! But, would you provide me some more details for it?? Do I need to make that PCB by myself?? What method would be the best?? Or is there any company that makes PCBs by looking ...

Hey. Maaan, it's been covered like million times around the web. So if it's been covered a million times on the web, would you please give me any link explaining what I should do to program a 29F032 on Willem PCB50B?? There's NOTHING about how to build/purchase any adapter for it.... but the flash ...

Hey there, I figured out that there's an easier route to program some SNES games rather than using 27C322 and doing all that nightmare rewiring. But as the title suggests, I have a Willem version PCB50B and I don't know if it's able to program these flash EPROMs like 29F016 or the mentioned 29F032. ...

So basically, are you able to program a 3MB game on 27C322 (4MB) EPROM?? Since 3MB are my biggest pain because when I deal with 1-2MB games, I easilly use 2x 27C080 (or some other combinations like 080+040 etc.), for 4MB I use 27C322 and for 3MB games I'd also like to use 27C322 because using 3x27C0...

I believe you'd want to duplicate the last 1MiB of the 3MiB rom to fill the 1MiB void left over. So the 4MiB rom would be filled like this: [Normal 3MiB Rom][Last 1/3rd of Rom] = Full 4MiB Concatenation That's what I also thought too, but shouldn't you fill it with the FIRST 1MB of data?? That's th...
