I just dumped vendor info off my packs.
All my packs are Type 1 with 8M memory（０ｘ１A) too.

Thanks for pictures.

I was wondering if Samegame and Gundom data packs are re-writable like 8M memory packs but I guess they have completely different ROM chip which is not re-writable.

Thanks,

I have same shining scorpion game so I looked at your save data by running it on emulator. Your save data has 2 save slots and one with name randomly selected. And another with boy's name who played the game. I also dumped my shining scorpion save data and verified that SA1 sram can be dumped. But I...

I tried but emulator did not recognize it as save data.
Maybe SRAM battery on my carts are dead.
I need to go shopping to get real snes console to see save data on carts too.

That's the second thing I did yesterday. Than I just realized that there is no way to prove if it is save data.
I will try to feed dumped data to emulator to see if game recognize it as save data.

I still can't find where is SRAM of SA1.
Maybe it is good idea to dump all banks and search save data from the dump.
I'll try it on Saturday.

Hi sanni, I soldered all cables back. All you need is REFRESH = LOW. I guess you shouldn't supply CPU CLK. Otherwise, you get corrupted data when clock goes into CPU CLK. So I think key feature you listed is good. Also, I tried different frequencies for CLK0 and CLK2. SA1 unlock flash chip very fast...

Hello sanni, I got my Arduino MEGA2560 Nintendo dumper sucessfully read SA1 chip carts. I tried using 12V external power supply - didn't work. Desoldered 1000uF big capacitor from console and attached right next to the cart socket - didn't work. Desoldered cables connected to PA0 - PA7, CPUCLK, PARD...

I tried adding 1s delay after enabling snesCIC, added 3.3V LDO, add 12F629 snesCIC trigger IC(Which is working on HK dumper), and added delay between setting address and read D pins. None of them worked. As sanni's advince, I will go buy and add DC 9V or 12V power supply to Arduino. I'm still wonder...

Hi byuu! If you have the ability to produce hardware of that caliber, is there no chance you can make a 21fx board using defparam's open source schematics / gerber files / etc? It look very awesome. Sorry I don't have any experience to make device like this... Is there anybody who sell this device? ...

My current Arduino sketch doesn't work with SA-1 at all. I think it's the menu's fault where you select between the different Nintendo systems, the SA-1 will lock up before you can select Super Nintendo. I don't think so. For hong kong dumper, I have physical switch attached to IC to enable snesCIC...

I think that 3.3V output of Arduino Mega 2560 is not good enough to drive 3.3V clock gen slewrate.
I will check waveform next week and add 5V to 3.3V LDO to see if it helps.

Thanks,

Hi sanni and skaman,

Thanks!
Neither of methods worked for me...
I guess problem on my dumper is different from others.
I need to check my waveform and circuit connections again.

Thanks,
Tamanegi

Hi skaman, Thank you for your advice. Sorry, I couldn't find any bridge/Jumper in sanni's hardware nor software. Besides, I used Wire.h and my own I2C clockgen configuration which is confirmed to be working on hongkong dumper and confirmed some clock coming out from CLK0 and CLK2 so I don't think br...

Hi skaman, I'm using sanni's Nintendo Cart Reader for Arduino Mega2560. https://github.com/sanni/cartreader/ Since I don't have SD card reader, Arduino fruit clock generator, nor graphical display, I modified code around so I can use dumper without 3 modules. To remove SD card reader and Graphical d...
