Not sure if it's the most recent version

Now if you could somehow design a drop-in replacement motherboard for the original SNES case that runs your code and offer it as a reward for a kickstarter at a price roughly around $100, you'd probably have to think about the $2 and $3 million stretch goals. Because let's be honest a pure source co...

Yes all you really need is an Arduino Mega, a SNES cart slot and some wires. But you also need to connect an SD card somehow like wiring a mircoSD adapter to the Arduino. https://abload.de/img/img_2815n7u3g.jpg Then you change the code like this: // If you don't have an OLED screen change // enable_...

You can find the latest version here: https://github.com/sanni/cartreader
Includes all the source code and pcb files. There is also a pinout in case you want to hand wire it.

So did the sender contact DHL? Because there is no contract between the recipient and USPS. Therefore USPS will just ignore the recipient since he is not their customer. The sender needs to go here: https://www.dhl.de/en/paket/hilfe-kundenservice/sendung/nachforschungsauftrag_international.html Also...

There is a similar thread in a german message board about the snesCIC and the PIC 12F629. I had the issue that a SFC with several different snesCIC/PIC12F629s would boot everything but SA1 games and only after replacing it with a superCIC/PIC16F630 the SA1 booted fine while the same snesCIC/PIC12F62...

You can reprogram it 100.000 times.

Me personally I can't understand why people still use very old and used Eproms when you can get new old stock factory sealed 29F032 4MB 5V flashroms on ebay from time to time(just buy bulk when they become available) that can be programmed with nothing more than an Arduino. Sure best case scenario w...

Book2 of the Snes Dev Manual speaks alot about the different SA1 registers but even with all that knowledge I wasn't able to make /WE of the sram go high. One interesting part in there was that by default the SA1 cpu is in some sort of sleep mode and first needs to be woken up. I wonder if maybe th...

I hooked up one of those cheap $5 logic analyzers: https://dl.dropboxusercontent.com/u/20912715/snes/Snes_Cart_Reader_Mega_Shield/sa1_logic1.jpg From the HY6264A-(I) Series 8Kx8bit CMOS SRAM datasheet: Note(Read Cycle) 1./WE is high for the read cycle. 2.Device is continuously selected /CS=VIL, CS2=...

If I understand this correctly there is a register that controls if the SNES CPU (which would be the Arduino) access to the Sram, so we would need to write something to this register first. 2224h SNES BMAPS 00h SNES CPU BW-RAM Mapping to 6000h-7FFFh (W) 2225h SA-1 BMAP 00h SA-1 CPU BW-RAM Mapping to...

Thanks alot :D So set the master clock(pin 1) to 21Mhz, don't output a clock to Sys Clock(pin 57), output 3Mhz to Cic Clock, output a low signal to refresh(pin 33) and high to reset(pin 26). And also make sure you got a stable power supply or at least a strong USB port. Pushed the changes to the git...

Thanks for the feedback, I wrote a little test program that just prints the cart's name and info over the Serial Monitor: https://dl.dropboxusercontent.com/u/20912715/snes/Snes_Cart_Reader_Mega_Shield/SNES_SA1.zip Key features: - sets PA0 - PA7, CPUCLK, PARD, PAWR, WRAM, REFRESH, EXPAND to output (w...

Does anyone know how to read/write Sram from/to SA-1 games?
