A generation of games,
wherever you need them

We build the runtimes that bring Java-era mobile games back. If you make hardware, we can put them on it. If you own the games, we can take them everywhere else.

Embed our runtimes in your hardware

Talk to us about your device →

Ship a catalogue of classic mobile games on your Linux, Android or RTOS based phones and devices. Our engines — J2ME, In-Fusio ExEn, Mophun and Flash — are small, portable native cores built for exactly this.

fits low-memory RTOS-class budgets · no OS dependencies · libretro ABI

  • Runs on low-memory RTOS environments — fixed memory arenas, footprints sized for the hardware class the games were written for
  • Portable native code with a libretro-compatible layer
  • Save states, per-title configuration and input mapping built in
  • Integration support from the team that wrote the cores

Re-release your Java-era catalogue on today's platforms

Bring your catalogue back →

You own games written for J2ME, MRE, ExEn or Mophun. We repackage them as native titles and handle the ports — you keep your IP, we do the engineering.

  • One codebase path from your original .jar / .vxp / .exn / .mpn files to store-ready builds — .swf, .n-gage and .mod as those runtimes land
  • Certification-ready packaging for console platforms
  • Cloud saves, achievements and modern input on every platform
  • Optional in-game upscaler for better graphics — a remastered look on TVs and monitors
  • Per-title or full-catalogue deals

AI-assisted remakes, at a fraction of the usual cost

A traditional remake means rebuilding art and code by hand. We use AI to analyse the running original and extract its gameplay, levels and data — then build new, modern software around it, with AI-assisted art generation for the presentation. A remake at a fraction of the usual cost.

  • AI extraction — gameplay rules, levels and data analysed and extracted from the running original
  • New modern software built around the extracted design, native on today's platforms
  • AI-assisted art generation — modern 3D or 2.5D graphics
  • Modern resolutions and aspect ratios beyond the original 176×208
  • Optional touch-first control schemes for phone re-releases
  • Human review on everything that ships

Publish in the Handyplay stores

Publish with us →

Handyplay ships with an in-app store on web, iOS, Android, Telegram — and the platforms above as they land. Put your titles in front of the audience that already came here to play this era of games.

  • Listing, delivery and updates handled by us
  • Your games run in the same engines the catalogue is tested against
  • Revenue share, no upfront cost
  • Early partners shape the store — it launches with your titles, not after them

Questions

What do you need from us to start a port?
The game binaries you hold rights to (.jar, .vxp, .exn, .mpn) and proof of ownership. We handle compatibility testing, packaging and platform submission from there.
Do the runtimes really run on RTOS-class hardware?
Yes — the cores are written for fixed memory budgets with no dynamic OS dependencies, which is what the era's games assumed in the first place. Tell us your memory and display budget and we'll tell you what fits.
How does an AI remake keep the original feel?
We use AI to analyse the running original and extract its gameplay, levels and data — the remake is new modern software built around that extracted design, checked against the original side by side. Everything is reviewed by hand before it ships.
What does console certification involve?
We maintain the platform-specific packaging and take titles through certification with you. Timelines depend on the platform; talk to us with the titles in mind and we'll scope it.
