I greatly enjoyed "So now that we're done moving the goalposts, we can start porting Unix to the Famicom Disc System" and "the kernel is running trust me".

Saw that on Hack a Day the other day. It was pretty interesting. The video said it needed the extra memory available in the Famicom Disk Drive to run the Unix port, but then he shows it running (via an Everdrive) on an unmodified NES.

I guess I'm just not familiar with the Everdrive. Does it provide extra memory the CPU can use similar to the FDS?

Hm, that's a great question. Maybe the Everdrive can provide RAM to the system as if it were on the cartridge (thus moving the goalposts again though only by a tiny bit)? It would have to, in order to allow people to play MMC cartridges...

From my understanding Everdrive works as a disk emulator for whatever system it's designed for and since this one supports famicom disk system roms I'm assuming krikzz probably designed the fpga on the Everdrive to cover the extra ram and what not. I am no expert in this stuff though so I could very well be wrong.
