J36 Ultra vs R36S WiFi: Which Should You Buy? (2026)

On a product page, the J36 Ultra and the R36S WiFi look almost identical. Both have a 3.5-inch screen, twin sticks, built-in WiFi, "15,000+ games" and a price around ₹4,000–5,000. Underneath, they're quite different machines built for different people.

We sell both, and we've pulled the game card off each one and counted every file. Here's the straight comparison, including where each one falls short.

The short answer

• Buy the J36 Ultra (₹3,999) if you want a plug-and-play console for 8-bit, 16-bit and arcade games, online fights with zero setup, and YouTube on the side. It's the better first console and the easier gift.
• Buy the R36S WiFi (₹4,899) if you want PlayStation, PSP, N64 and Game Boy Advance games, an open system you can customise, and online multiplayer with your own friends. It's the enthusiast's machine.

Specs side by side

The game libraries: same headline, different shelves

Both consoles land at about 10,000 unique titles once you strip out regional copies and duplicates. That near-tie is misleading, though, because what's in those 10,000 is very different. These are the numbers we counted on retail units:

Two things stand out.

About a third of the J36's library is Atari 2600 and original Game Boy. Those are 3,453 titles from the late 1970s to early 1990s, which is where its larger file count comes from. Some are genuine classics, but few people will play more than a handful. If you remove those two systems, the R36S WiFi has the bigger library of games people actually reach for.

The R36S goes much deeper where it matters. It has five times the Game Boy Advance library and about 4.5 times the arcade games, and it covers N64, DS and Dreamcast, which the J36 doesn't attempt. It also carries 68 PS1 and PSP titles against the J36's 26.

You can search both libraries game by game: J36 Ultra full game list and R36S WiFi full game list.

Performance: where the hardware shows

On paper, the J36's octa-core chip sounds stronger than the R36S's quad-core. In practice, Cortex-A7 is an older 32-bit core design, and the RK3326 in the R36S pairs newer 64-bit Cortex-A35 cores with a Mali-G31 graphics chip. That GPU is what lets the R36S run N64 and PSP games at all.

We've measured the R36S extensively. Most of the PS1 library runs at full speed, and lighter PSP games are very playable. We keep an honest PSP tier list and a guide to N64 and PSP settings that work. Heavy 3D PSP games like God of War are possible, but only with careful tuning.

We haven't benchmarked the J36 the same way, so we won't invent numbers for it. The plainest evidence is what its own makers ship: 16 PSP games and 10 PS1 games, described as a bonus. Our own listing says the same thing: the J36 is at its best with 8-bit, 16-bit and arcade games, and it isn't a PSP machine. For NES, SNES, Mega Drive and arcade fighters, both consoles play smoothly and you won't notice a difference.

Online play: two different ideas of multiplayer

This is the most interesting difference, because both consoles have WiFi but use it very differently.

The J36 Ultra has a built-in online arcade. Connect to WiFi, open the online section, and you're in a lobby with real players. Quick-match drops you into a fight straight away, or you can join a room. The line-up is 22 arcade games: Street Fighter II in several versions, King of Fighters '96 through 2002, Samurai Shodown II, Marvel Super Heroes vs. Street Fighter, Metal Slug 1–3, Final Fight and Knights of Valour. There's no account and no setup, so it works the first time.

The R36S WiFi uses RetroArch NetPlay. One person hosts a game and a friend joins, from the next room or another city. It works across far more systems (SNES, Mega Drive, GBA, PS1 and arcade), so you can play Contra co-op or Tekken 3 head-to-head. The trade-off is a minute of setup and needing a friend with a compatible device. You won't be matched with strangers. Our R36S multiplayer guide walks through it.

In short, the J36 is better for a quick fight against anyone, and the R36S is better for playing a wide range of games with people you know.

Beyond games: YouTube vs an open system

Because the J36 runs Android, it does things the R36S doesn't out of the box. The YouTube app is pre-installed, and there are video, music and photo players, so you can load films onto the card for a long train journey. For kids and casual players that's a real plus.

A note for parents: it's the regular YouTube app, not YouTube Kids. Treat it like a phone for younger children.

The R36S goes the other way: it's games only, but almost everything about it can be changed. You can swap in a different firmware (every option compared here), run native PC ports through PortMaster, overclock it, or switch to MinUI for a minimal launcher. There's a large community building for it, which is why we can keep publishing guides like these. Determined tinkerers can even install a desktop browser, though that's a project rather than a feature.

What about the cheaper R36S?

There's a third option worth knowing about. The standard R36S at ₹3,799 is actually cheaper than the J36. It has the same body and emulation strengths as the WiFi model, with a single RAM chip and no WiFi. If you want PS1, PSP and GBA games and don't care about online play, it's the best value of the three. For a younger child, its complete lack of internet access is a feature. We compare the R36S models in R36S vs R36XX vs R36 Plus.

Who should buy which

Common questions

Can the J36 Ultra play PSP games? It ships with 16 PSP titles as a bonus, but it isn't designed for PSP. If PSP or N64 is what you want, buy the R36S WiFi.

Which has more games? The J36 has more files (16,616 vs 15,058), but both have about 10,000 unique titles. The J36's lead comes from Atari 2600 and original Game Boy games, while the R36S has far more GBA, arcade and PlayStation-era titles.

Can I add my own games? Yes, on both. The J36's card can be swapped for a larger one. The R36S WiFi starts with a 64GB card and can also take games over WiFi.

Which is better for online multiplayer? For instant matches against strangers in arcade fighters, the J36. For playing many different games with your own friends, the R36S WiFi.

Which is better for a gift? For most children, the J36 Ultra: it's cheaper, gift-boxed and plays the moment it's switched on. See our Diwali gift guide under ₹5,000 for more ideas.
