End of an era
I am selling my Broadband Adapter (NIC) for the Sega Dreamcast. Been tidying up at home and it was time to admit my days as a Dreamcast hacker were over – my last posting to LKML, a filesystem driver for the File Allocation Table (FAT) filesystem found on the DC’s “Visual Memory Unit” flash device…

New version of mkfs.vmufat available
I have posted a new version of mkfs.vmufat, a tool to make a VMUFAT filesystem, at my GitHub repo: it will now format a file as VMUFAT volume (if you use the -f switch). Would love to hear your feedback – my posting of the source code for the filesystem itself generated a bit of…

More delays for VMUFAT
Obviously the whole world is waiting for VMUFAT to hit the streets, but it looks as though it will have to hold its collective breath a little longer, as I have hit more delays. Working with big volumes (several megabytes) reveals the code eats a lot of memory in ways I don’t yet fully understand.…

Spoke too soon (of course)
It’s like the curse of the software demonstration: it doesn’t break until then. I discovered as soon as I posted that I was ready to (try to) push the VMUFAT stuff up to main line that there was a bug in the software. Very large VMUFAT volumes were not being properly handled. But I think…

VMUFAT: almost done (I hope)
About a decade ago I first wrote some Linux kernel code that would handle the filesystem on the little slab of flash storage that came with a SEGA Dreamcast Visual Memory Unit (VMU). A few attempts to get this in the kernel mainline then followed. It was a bruising experience and unsuccessful. But I am…

One of those debugging nights
It must be a situation every programmer is familiar with – you write some code, you are pretty pleased with it, but it just doesn’t work and while you know it is only a small thing that is stopping it from functioning properly, but you just cannot track it down. That is exactly where I…
