Few people have a dedicated player, but there are still plenty of video game consoles (PS3-5, XBox 360/One/S|X, Wii U?), which make great bluray/DVD players. We’ll see how the next generation of consoles turns out, given how hot these companies are to cut out physical media altogether.
Mods can help a lot!
For example, there’s a mod to increase the text size: https://www.nexusmods.com/eldenring/mods/650 (It hasn’t been updated for awhile, so I don’t know how well it’d work for recent patches)
If the game is just too difficult, there are also mods to help with that. Mods can adjust the difficulty, add FP regen, unlock summoning, etc., or completely overhaul the game (I had a lot of fun with the Convergence mod last year)
