Awesome! I am glad that you finally got it working! do your own chips also work on the new programmer?

I used some right-angle headers for my adapter. If you didnt use a ZIF socket, it would fit just fine with straight headers. There was also the thought of making the board as small as possible to reduce the production cost. I did have the thought of making a 40 pin version for the GQ-4X, but I do no...

Ziggy, I completely agree with everything you have posted. Reading your post sounds like you live inside my head...

Now i'm being offered the cart for $77 shipped with my save on it from ziggy, Should I take that up? Its $1 more than the total of retrousb and it has my save on it... Should I forget my save? Question is, do you want a cart that looks authentic and good in your collection, or do you want a cart th...

Ive ordered three sets for a total of 36 chips, and I have only had two chips with bent leads, both of which I was able to straighten without a problem.

He does not have any up right now, but this guy has pretty good deals on these.

It looks like there is a corrected Type II adapter, now called the Type III on BuyICNow.com.

From a quick glance, it looks like the A20 and A21 lines have been swapped back to be correct.

For 32mbit chips, without reinventing the wheel, only the AMD/Spansion AM29F032B and the ST M29F032D chips are compatible with the commonly available adapter. I am sure you can design an adapter for just about any kind of parallel 32mbit flash chip, but those are the most common, and therefore least...

Those are very useful.. Mine was an NHL 97 however. I test every TSOP chip I make using this board.

They have learned to emulate the CX4 in an FPGA or CPLD, at least that is how they are doing it on the sd2snes, and there is some sort of Altera CPLD on this board as well.

it sort of looks like a clone/ripoff of the sd2snes

nope, the SNES physically cannot access the rom faster than 150ns, so any capability beyond that will go unused.

Anything lower then -150 would work for your flash chip. that indicates the speed of the chip, but the SNES maxes out at 150. Anything faster then that will just go unused.

That chip was erased, blank checked, written, verified, erased again, and blank checked again just minutes before boxing it up. I can say that I am 100% sure that the chip is fully functioning. Again, that was with my GQ-3X Don't worry about returning it, consider it a christmas gift, heh. So, basic...

Question for you, the A19/A20/A21 connector on the side. What should that end up being connected to? Those should connect to the appropriate headers on your willem-type programmer. The Willem programmer only has 32 pins providing no socket location for A19-21, so you jumper them to the additional a...
