What's actually worth it, and what to skip no matter how good the spec sheet looks.
Under $100 is where retro handhelds stop being a toy and start being a real hobby entry point — but it's also where the market is flooded with near-identical clone boards wearing different shells. The devices below are the ones actually worth your money, not just the ones with the loudest listing photos.
The default recommendation for a reason. Rock-solid Linux-based firmware, a huge emulation range up through PS1, and enough of a community around it that troubleshooting is never more than a search away.
This is the same family I've actually got — plastic and D-pad feel exactly as budget as the price suggests, but nothing about it has stopped working or felt like it was going to. For the money, that reliability matters more than the mushy buttons.
The pick if pocketability is the priority — it's genuinely small, with a screen that punches above its price. The tradeoff is a tighter control layout that larger hands may find cramped over long sessions.
A step up in screen size and body feel from the 35XX line, sitting right at the edge of the $100 mark. Worth the jump if you want a bit more PS1-and-below headroom and a larger display without crossing into Retroid pricing.
I haven't put real hours into a Miyoo Mini Plus or an RG34XX/RG40XX myself — those two picks are built on specs and other owners' reports, not my own thumbs, so weigh them accordingly next to the RG35XX pick above.
Default pick → RG35XX Plus/SP. Want smaller → Miyoo Mini Plus. Want a bigger screen and don't mind pushing toward $100 → RG34XX/RG40XX. Skip anything unbranded promising a suspiciously huge game count.
If I'm handing this list to someone and they can only buy one thing, it's the RG35XX Plus/SP — not because it's the best of the three on paper, but because it's the one I can vouch for after actually living with it. The other two are good bets on reputation and spec sheet; this one I'd stake my own name on.
