Total success!!! Now I can dump all my n64 Carts
Thank you Sanni
Thank you skaman
Thank you MichIK
Thank you themanbehindthecurtain
And thanks to all the people who worked on this project
I still have not received the connectors purchased in China. I’m tired of waiting for them. But last Friday I received by mail the pcbs of version v5B of sanni, which I had bought more than one month ago in China.
To my despair, for not having received the connectors. I decided to try one of the pcbs received last Friday. So I decided to check one pcb at any price.
So I removed the connector of my Passport Plus III and I use the connector on the pcb adapter for N64.
Then I dismantled my Snes game adapter for NTSC and JAP games, I took one of the two connectors and I use it on the main Board: the Nintendo Cart Reader pcb. This connector does not included all pins but takes the pins needed to work with the N64 carts.
I’ve used a few metres of desoldering wire, but the result has been positive
Then, I assembled all the circuit and I place all the essential electronic components to make it work in N64 cart reader mode.
Now everything works perfectly with sanni pcbs, it is clear what the problem what I had and by which the circuit did not work properly was the length of the wires.
I’ve done my first dumps of the cartridges with chip MN63F81MPN, thanks to the skaman information, using the 29L1101 mode.
The rom and the flashram savedata are fully functional, they work perfectly on my Everdrive 64 and I don’t have to do the saveswap. The ED64 recognizes the savedata in the SAVE folder at the first time and the rom of course.
By the way skaman, I could not get the tool: “saturnu’s Saveswap from Krikzz forum” all links are broken and I could not find it on Google, so I can not test these files in an emulator, I’ll keep looking, thank you very much for your help.
By the way I’ve discovered something curious in the operation of the circuit:
I can do the reading of the savedata on the cart in “29L1101” mode, without any problem this works fantastically well and the save data is fully functional. But when I try to upload the savedata to the cart again in this mode: “29L1101”, the program gets frozen in that moment and on the Oled Screen says: Erasing Flashram and the circuit is blocked, it does not pass that point. Then I have to turn off the power to the circuit and to restart it again.
But if I upload the savedata in autodetection mode to the cart, then the circuit upload it perfectly and without any problems. What might be the problem? I will continue investigating this matter.
Sanni thank you very much for making reality something what I had been waiting for, for many years. I’ll send you a PM with the files that I have obtained, to update the sketch with the flashram MN63F81MPN. By the way I have a Paper Mario cart with 29L1100KC chip, you have to update the list.
Thanks to all
