Created a binary for windows using minGW and libusb. So i can confirm that quickdev16 will work under Windows.
Finally we found a better name for the snesram and renamed it to ‘QuickDev16 USB’. Final PCB layouts are ready and will be send to china soon. So in about 2 weeks we will have our first PCBs.
- 16 MBit Sram for Rom storage
- ATmega644 MCU for housekeeping
- USB connection for ROM upload
- ucon64 software compatibel
- PAL/NTSC CICs are supported
- Lo/Hirom support
- Reset trigger from cartridge possible
- AVR USB Bootloader for quick firmware uploads
- Snes bootloader intro
- Snes powered, no power source needed
Stay tuned for more features, especially debugging helpers
Things are going well. Have added some features to the software side and also got some stuff working hardware wise.
Can confirm that US/JAP roms are working.Only tested EU roms before. Used my japanese Nintendo junior and a japanese CIC to confirm that the snesram is working with that setup too.
Max and i added an bootloader to the AVR software toolchain. Now its possible to flash the AVR firmware via the same USB cable as for the normal bulk transfer. So no extra ISP programmer is needed to change the AVR firmware. This is super fast, can flash the 16kb client side firmware in like 3 secs.
Added a reset line trigger to the snes bus. Now the client software can reset the snes after uploading the software. So its possbile to push a rom via ucon64 from the pc and then reset is done by ucon64 and the firmware. No interaction needed from there.
Max is refactoring the schematics so that we can send them over to the pcb fab soon. Stay tuned.
Max took a quick break from his vacations and was able to work on the new hardware revision of the snesram. Its mainly a bugfix to version 0.1 . We also did some cost reductions. Most obvious is to go for 2 Mbyte of sram instead of 4Mbyte. It just make the PCB smaller and less complex. I guess this should be alright with most peoples needs.
We gonna print a small amount of PCB and will take pre-orders as soon as we know they will arrive. Not sure about the final price, depends on the PCB costs and if we get
better prices for the sram. Stay tuned.
