Making repoduction NES/SNES carts?

I will look at all software versions new and old, but I did have better success with the older ones but it just never verified or couldn't get the ID of the chip unless I shut it off then turned it on and it got the ID but who knows if the damn thing was ever programmed correctly since I can't verify.

 

I had to rewire the Adapter for mounted chips, and it works every time on the GQ-4X.

 

I have the GQ-3X but explain to me how you rewired what to what so I can see if it works for me.

 

Mmmm not sure if you are using the same adapter as me, but I had to rewire the A19-A21 to some pins.




This is my adapter
[External Lines]
A19,A20,A21

1 - 2
3 -4
5 -6
7 -8
9 -10
11 -12
13 -14
15 -16
17 -18
19 -20
21 -22
23 -24
25 -26
27 -28
29 -30
31 -32
33 -34
35 -36


So A19 external line goes to pin 34, A20 goes to pin 33, A21 goes to pin 35

Hopefully I explained it ok.. lol

let me know if helps.

 

Ok so I understand correctly you are using one of these? I'm using This Adapter which connects to This Adapter and it connects to my programmer but I can't get any chips to ID, I tried various chips I bought and non ever ID correctly its always 0000,FFFF,7F7F. I did order that adapter I linked to first so hopefully when it comes in it will solve my issue.

 

im using this adapter:

Yes that is the one I linked above first, I have that on order and should get that in 2 weeks or so. It's a damn shame that the official adapters from mcumall don't read this chip properly otherwise I wouldn't have spent the money on them and had gotten this adapter sooner. Thanks for the info none the less.

 

The official adapters should work. APE is using the adapter you just bought and has issues too.

 

So any work arounds for these adapters or is it just these chips that have issues being detected by this programmer?

 

The rewiring I told you. Mine works Every time 100%, Read, Verify, Write, Erase, no problems at all.

 

I don't have that adapter yet, I was referring to the ones made and sold for this programmer by mcumall.

 

Ahh crap sorry about that, mcumall products are a bit buggy as it is, it is hard to ID those flash chips without even being mounted!

 

I should have it by next week and will post back with the results then, also are there any other flash chips being used besides these from AMD for reproductions?

 

M29F032
MBM29F033

 

Damn these fuckers aren't getting any cheaper are they? Have any good suppliers of these chips?

 

Ok I'm about to just toss this piece of shit willem programmer out the window. I tried your rewiring method above it didnt work I have the zif32 not the zif40 on my programmer the GQ-3X. I tried following this guide too and its for the GQ-4x and not my GQ-3X, and using the image of the adapter board I soldered the A19-A21 to where the trace leads to on the pins 27,34,36. Following the trace lines to the A19-A21 header leads to those pins but non of these methods lets me ID this chip and I know my soldering is good, I tried a few different boards I soldered the chips to (all the "R" locations are bridged) and none can ID. Can anyone help or post a definitive guide on how to wire the adapter to my piece of shit willem? Or has anyone had better luck with a different USB programmer that isnt astronomically expensive something less than $100 that can program these chips without all of this bullshit.

 

The GQ-3X is not a piece of shit. The problem is you are trying to use the 29F032 and that adapter which has numerous issues which are not widely talked about. I bet if you had normal eproms or flash roms in DIP packaging you'd have no problems.

 

I'm sure as well but I already invested time and money into this programmer and its official adapters to not get anything to ID. So I went the DIY route and used the willem to tsop adapter that many claim to use and work but I get the same results. I have a question that hopefully someone can answer me: Do I need to wire anything to those pins A19-A21 on the adapter board to any other pins like pichichi010 did for his GQ-4X? Remember I have the 32pin zif GQ-3X not the GQ-4x 40pin zif.

 

I finally got it to ID, I made 2 adapters and the second was good and had to do a little resoldering of the TSOP chip and its all good.

 

Hmm. I should try making an FF5 with my 1997 translation. How I'd do it is to make my own PCB by designing it and buying its manufacture online, buy ROM chips, batteries, SRAM, a CIClone chip, and one of those custom-manufactured SNES cases. That way, I wouldn't be destroying an old game in the process.
