Thanks for the reply! Lacking more options, I actually ended up soldering a new board with my last chip. That one works! So it would seem I ruined the other boards. I also had a microscopic bridge between two pins that caused some frustration on the new board, but once I cleared that I'm able to wri...

Another update: So lacking anything else to try, I soldered my last chip to an adapter board. This one id's! So somehow I fried or otherwise screwed my other boards. I have no idea how that could have happened. The only thing that came to mind was not cleaning the flux off well enough. Switched flux...

So I'm at it again. Reinstalled Windows last go round. No change. So it's not a software problem. I've soldered up a new adapter board today. Just in case. No change. So far the only part that I haven't actually remade is the extended address adapter that came with the GQ-4X. Which I assume is behav...

Ug. Okay. I've tried the following versions of the software this evening: 5.03B 6.13C 6.16 None of them will ID any of my chips. :\ I can Erase/Write a couple of the chips. The other one still doesn't work (as expected). The previously working chip no longer runs after Double Write @ -2. The new chi...

So I probably had it full working, but I missed your advice on checking the dump. That was a good idea. Too bad I already blanked the good chip. :P Now my programmer is on the fritz... So I'm getting back to this. Had a heck of a time solding another chip today. :lol: I'm also getting the weirdest b...

5.03 doesn't explicitly support AM29F032 where as the 6.xx versions do. There is an M29F032B*TSOP40 support... which is what I assume you are using? I'll give it a try anyway! EDIT: No luck. Verify fails at around 22%. I'll try once more at slow speed. dy H/W Re: GQ-4X Re-1.41 USB Driver Re.2.0 Soft...

I've seen a lot of people hating on them, but the truth is the MCUMall products are well designed and responsibly produced and are still affordable. For my purposes buying a very expensive "better" chip programmer doesn't make sense from a number of stand points. Thanks for the software ti...

I'll try double writing tonight. Yes, I indeed have the adapter! That's what I was referring to when I said their adapter for the A lines. I'll post a pic. For the record I had to cut notches into the adapter just to get it to fit with your board, and it's still a tight fit. While I haven't tried it...

I'm using AM29F032B-75EC with an UL94V-0 (below) adapter board. The resisters are bridged with wire. I am programming it with GQ-4X with their adapter for the A lines interfaced through your adapter board. No ZIF this time. It seems to error at a set of multiple addresses each time I verify about 30...

Huzzah! I have a chip identifying correctly... Now a silly question: Just to verify I have this correct... in the GQ programmer, you can select the data format. I've chosen ROM and left everything default. Is this a safe way to go? I seem to finish writing the data but I get an error on verification...

I got the adapters and got everything wired up, but the chip isn't giving me an ID yet. :\ I'm going to solder another 29F032 to an adapter board in an effort to isolate the problem. Checking all the leads on the adapter seems to work okay, though it might be the ZIF socket I installed in the adapte...

I ordered 4 of the pre-desoldered chips from BuyICNow.

I have a NHL 97 too, but it's PCB is in better shape; so I'm using that one for one of the cart's I'm making.

Picked up an NHL 95 to make into a test cartridge, since I don't want to have to resolder chips every time I want to test. So yeah... nothing as fancy as what you all have going on, just a cart with a dip socket.

I picked one up at my local Fry's and it works really well actually! It does require a little Dremel work to get it nice-nice, but the finished product is good. Philmore plastic battery holder The modifications that are needed: - The terminals need to be pulled out before working with the clip. They...
