That sounds neat! I have an old kobo clara HD. I run koreader through nickelmenu, and I have to let it load its native software before selecting and switching into koreader. I'm also under the impression that if I connect it to the internet I'm at risk of losing my setup via wireless update. I think I had to delete a config file by mounting the device to linux to be able to even use it without a walmart / ratuken / whatever idp account in the first place.

Everyone here is lauding kobo for being so 'open' and 'hackable', but when I set mine up in 2022 it kind of just felt like they just weren't as good at fucking me over and subverting my intentions as Amazon. Kind of like being an intruder in your own home. Have things changed? Should I update my setup?
