I use a simple switch from 32 MB to 48MB.

Kogami! I am glad to see that you are here as well.. I have gathered alot of my knowledge from you and your tutorials. Your threads on various sites are what have really encouraged me to start this project of mine.

I'm glad to hear that

I was surprised to see that someone else had also manufacture the same test card Super Nintendo. It took me a long time to design it, but ultimately it's really useful and easy to use.

Your site is very interesting, even if it is in Japanese, it is easy to understand, there are lots of very useful information.

re:rkrenicki

Any luck with posting the PCB?

Also, I'm following the other thread on the TSOP adapters. Is it true that the Type I ROMLAB style boards can't be programmed directly? Or rather, to state for clarity:

Which boards can be used for writing to the EPROM through the adapter? What steps need to be taken to ensure this is possible? "Why?" is also good to know!

I had some family issues to deal with last night, so I did not get a chance to work on it.

I intend on reworking it and posting it sometime today.

I know that my adapter works fine for Type II boards, I have never owned a Type I, so I cannot speak for those, but I do not see why it wouldnt if the jumpers on the end are set correctly.

Okay! I edited my design to include larger holes, so more sockets and headers should fit better then my original CAD.



Here is a link directly to the CAD files: http://www.retrohacker.info/pcb-cads/Wi ... dapter.zip

Laen's PCB service located at http://dorkbotpdx.org/wiki/pcb_order is a great place to have these made up. It should cost right about $8 to have 3 boards made up from this design.

This adapter is also useful for reading back original Mask ROMs, that is how I verified my Seiken Densetsu 3 rom file. This is completely based on someone elses design, but unfortunately I cannot find the original site to properly credit it. If I find it, I will be sure to update this.

EDIT: It was Peccost! His links are 404'ing now, which is why I didnt see it. Peccost, if you are reading this, thanks for your original design! This is a slight modification of yours and published as a set of Gerbers.

No problem!
But it must NEVER be used to make money in any way.
Only for personnal use and passionated people!

I tought this design used to be sold at that french website along with tsop adapter (back when they were hard to find). Am I wrong?

Thanks again for posting those files. I'm ordering some once he starts orders again in December.

Well, this particular set of CADs was made by me. However there really is only one way to do a Willem to Mask ROM/TSOP adapter, so they are all inherently the same.

Routing, spacing, and labeling will obviously differ as there are thousands of ways to make a round wheel, but in the end they are all just that.. a round wheel.

I should be getting my boards soon. Huzzah!

Re:rkrenicki

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 address lines header on the board.

Here is a photo for reference, this is of the GQ-3X programmer, but it should be similar for others.

Oh right. Duh. I realized that upon rereading the question just now! Thanks for the clarification though, the image certainly clears that up.

I will check your site out as well!

Finally got my shipment from BuyICNow. Man the pins on the AM29F032 are tiny! They were out of the -90EC so I had to go with the -75EC... I hope that's acceptable!

I'm still waiting for the adapter from the DorkbotPDX PCB order... apparently there was a mixup at the board fabrication place so it's running super late. :\ I guess I could breadboard one in theory, but that seems like a pretty silly investment of time at the moment!

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.

Is there an advantage to the faster chips? Just curious.

Still waiting for the adapter PCB's. :\ I'm probably going to try to solder of the chips tomorrow, I think.
