Forgot to add, I also developed a BlueWave-compatible offline-reader called Wolverine that worked for all Fido-style networks: https://github.com/ssg/wolverine
It was quite popular in Turkey in the 90's.
You can try it out in DOSBox here with some random HitNet packages: https://github.com/ssg/wolverine/releases/tag/2.32
I completely forgot about Wolverine, but you've reminded me I was using that back in the day to read my mail from Fidonet point (as well as Bluewave).
WOW! Your FatalVision (1) is absolutely shiny! Wish I'd had it in the 90s.
Respect for the file_id.diz (2)! I thought mine was the last one on GitHub.
