Gameplay recording on Handhelds

Hi. I have a somewhat unusual question. Has anyone here recorded longplay-playthroughs on handheld consoles? I need some advice: which handheld should i get that can handle both running the game and recording video in high (!) quality for extended periods? The target games are primarily GBA and PS1 titles.

I realize that emulating these consoles is a breeze for modern handhelds, but recording high-quality video, especially over long sessions, is a much more resource-intensive task.

I`m currently looking primarily at the Konkr Pocket Advance and Retroid Pocket 5

If anyone does this kind of thing, please let me know which handheld you use and, if possible, share some of your recordings.

Thanks!
