SNES Repro 27C801 on Willem PCB50 Error

I would suggest you just buy a GQ-4X from mcumall.

All the adapters you already have for the willem will work and the GQ-4X is usb. Will save you a ton of headaches.

I cant post any pics as I do not own a para willem anymore, I upgraded to a GQ-4X which I have since sold and upgraded to a "professional" programmer.

If you end up getting fed up - you can send me the chips + data and I will program them for you. But I recommend ditching the para programmer.

 

I do not so much ic programming its only for some japanese square games i like to have with english text. And im not a fan of emulators...
When you programm me some of them, you can have some eproms for your work, is that ok for you? I bought 16x M27C801-150F1 and 5x M27C801-120F1 .

 

Sure, sounds like a deal.

Drop me a PM with link to files (or ask for my email), your return address etc and I will send you my details.

 

Hi i will upload some pictures later on as i have the same programmer.

I have some 27c801 i would like to make my own unrleased snes games for my own use.

How can we redo the mask rom pin out to use the 27c801 eprom?

 

I finaly did it. It was the jumper for old/new Software. Jump it to PCB3B.
