Yes i remember it well - from console (NES, SMS) to various 8 bit like atari 800, cdr 64, the euro machines like spectrum and amstrad and the msx machines. The scene was centred on some sites but also within others, i remember allegro library sites with showcased remake games.

maybe it faded when that era of games moved into a more "distant" past, or it moved more into mobile - you remember all the .exes and so on? 😀 that doesnt happen much now in comparison with mobile, browser and so on

also, many remakes were done - and once done, is a new remake a re-remake?

there's also the whole unity and other advanced game tools where the ideas of that past - write a game engine, use a graphics lib, rip or create some graphics and slowly build a game full of subtle bugs and fun memories - have faded in favor of rapid dev 3d engines where its all done with visuals, load this model, load that, create even scripts, do some other stuff and suddenly its a full blown FPS

finally, that era coincided with rapidly advancing emulation tools - but now, and in the last 10 years, there are emulate-anything apps and access to "all of them" libraries of games, maybe that saps the demand too, or at least the motivation to write a game remake
