Re: Introducing the VeriSNES (FPGA-based SNES)

Actually, someone (sorry whoever you are, don't feel like going back through all the posts to figure out who it was XD) posted an idea earlier that I could have source code release goal and then stretch goal to make some actual hardware. I thought doing that or something similar was a really cool i...

Re: Introducing the VeriSNES (FPGA-based SNES)

I just randomly found this project and I must say it is an amazing work! So how much is ~8,000hrs, 83k lines of FPGA-vendor-agnostic Verilog code, and the myriad possible applications worth? [...] I would need to make enough money from releasing it that I won't feel bad about everyone that's going t...

Just want to say thank you for all valuable input. I successfully made it working after some trial n error.

Re: Controller port clocking

Thanks for the informative replies!

When I try sending data on the data pin, it looks like the NES is pulling it low. Is that an expected behavior?

Controller port clocking

Trying to build a custom uC based controller adapter for the NES (American model). Though I'm surprised over the clock pulse I get from the NES. First, it looks to be active low in contrast to reference diagrams, but most strangely the clock pulse is very short. About 1 us. 20160903_223738.jpg Chann...

Re: SD2SNES, sending rom over USB?

Ok, thank you all! As I suspected, nothing is really implemented yet. UART would be quite slow I suspect, and regarding wifi SD cards, I have never seen one able to receive data (only send). Anyway, for now I was only curious over the USB port and not about other options. For now it seems like it's ...

SD2SNES, sending rom over USB?

My idea is to crossdevelope on pc, sending the resulting rom over USB, resetting the SNES which will instantly run the code. Is this possible with the SD2SNES? As I cannot find any information about it, my guess is unfortunately that this is not yet implemented, or in worst case not even possible wi...
