Looks like the card image is still missing some critical kernel data. I'm surprised that no one has the actual Memory Card file image we need in order to boot this thing up.

You need the missing tool to build a rootfs on a memory card. I suppose you could look through the code to see how it's mounted and try and to understand the format.

I tried this years ago with a pre-built image, and that was always the stumbling block. It didn't output and video from memory, just serial. The tools to build the rootfs was not included in the source.

I assume the rootfs image they had for a memory card had busybox on it or something simple to get up and running.

Honestly the best thing would probably be to just build an entire new system of Linux, but it's not going to be much use unless the 8 MB RAM modification is done and we have a keyboard on the PlayStation. Getting Ethernet communications would also be ideal but that can be done last. It's a lot of work and a big project, but it's doable and it would be super awesome :)
