As proposed by Andreas (82MHz) , let's start the intruduction megathread.
I'm felsqualle, retro-computing enthusiast in my free time and a Linux systems administrator at work. I'm a project co-lead of ScummVM and the author of fabulous.systems.
Around 20 years ago, I got introduced to WinFellow, WinUAE and NESticle. In fact, at this point, I wasn't even aware that an Amiga is not a "normal" PC and that there were way more systems than I was aware of. Then ScummVM happened and things escalated quite a bit.
Nowadays, I'm mostly interested in MS-DOS and the Windows 9x era because that's what I used most of the time back in the day. I recently got into software preservation, so I'm slowly going through my software and games catalogue, trying to backup as many discs as possible.
For some reason, I got into old video stuff a couple of months ago as well. For example, I purchased both the PAL and NTSC versions of the Special Extended Editions of The Lord of the Rings and now I'm trying to process them to make them as watchable as possible on modern TVs. Yes, I somehow like the "crispy" look of DVDs. Actually, I prefer it over 4k for movies...
