A question on playing Java games

[Polemic]

So, I was going to buy a retro handheld to finally play the games I wanted to play as a kid (I've never had a Gameboy or something like that, I could only watch my friends/classmates play).

But what I did play were Java games (on mobile phones), and I'd really like to revisit some of them, too. J2ME/Android emulators are not very comfortable for me, and I feel like I'd do better with physical buttons.

So I've been planning to also buy a cheap (non-smartphone) mobile phone just for Java games, and...

Yeah, my question is: is there any handheld that's comfortable for playing Java games? Has anyone tried it? How did it go? (or would it also be done through J2ME on Android, but on a handheld?)

Thank you in advance.

J2me loader seems very good. You just have to set it up. Although it takes a long time to set it like a keypad but it would work. The only issue is your screen size
