npub1rp67d898y4f9ssalpjeldmhaehx9m68206srgldwujldl6kuaxuss4wzqe (npub1rp6…wzqe) It is a temporary switching to read/write to write the disk sectors that house the high score table, for a particular game.
For the Atari, I used three unused bytes in the ATR header to specify a starting sector, and a number of consecutive sectors. If this header is detected at mount, it is a high score image.
If a write happens to these sectors, the FujiNet will re-mount the disk as read/write, write the sector, then re-mount read-only. Repeat for any consecutive sectors.
Then I wrote a series of scrapers in C which run on the same tnfs server, and read these disk images, and create web pages, and update in response to inotify modify notifications, making it real time.
