Basic Questions

Getting Started

Diving into your PocketSprite is very easy. Each device is delivered with a quick instruction manual - which you can download here if you need to refresh yourself.

We've also created a comprehensive tutorial video - that explains everything you need to know about the PocketSprite, including:

At the end of the video you'll be a PocketSprite expert.. and if you have any more questions, you can reach out to our fantastic customer support.

What can it emulate?

PocketSprite comes pre-loaded with two emulators, GNUBoy and SMS Plus, that allow you to play every single game on the following platforms:

We also have an experimental NES Emulator available.

When you’re tired of the pre-loaded open source games, uploading a new ROM is literally a one-click process. It’s done over-the-air. On Windows, Linux, Mac, or Android, no cables or drivers needed – just connect to PocketSprite’s Wi-Fi network, upload the ROM through PocketSprite’s web interface, and you’ll be playing.

Storage Space / How Many ROMs?

The amount of ROMs you can store in the PocketSprite depends on their size. PocketSprite has 16 MiB of flash, of which about 2 MiB is taken by the OS and emulators. The remaining 14 MiB can be filled with ROMs if you so desire. You can fit more than 100 smallish (128 KiB) ROMs, or ten or so large (1 MiB) ROMs.

However, the Wi-Fi interface allows you to quickly and easily add and remove ROMs in one click, so management is never a problem. Likewise, you can remove a ROM, but chose to leave its ‘state file’, meaning that if you ever place the ROM back on the device, your game-state / progress will still be there.

Turbografx/PC-Engine emulator?

A TurboGraphics emulator should be doable, although it’s hard to predict how many of the additional TurboGraphics peripherals it would support. However, at the moment, there is no emulator in the works, although one might be ported in the future.

Are there any binary blobs on the device?

Our microcontroller is the ESP32. Currently, its BlueTooth and Wi-Fi drivers are not available in a source form. As such, The Chooser (the app that displays the main menu as well as allows you to upload new applications) is thus not 100% open source, for reasons outside our control. Apart from that, the emulators, the bootloader, and the rest of the Chooser are entirely open source; the emulators and SDK are already released on https://github.com/PocketSprite. (Note that we will release the chooser and bootloader later on, and that the SDK is not in the final form we’d like – it’s good enough to compile the two emulators but we’d like some better APIs and documentation for others to use.)

Does PocketSprite include a Game Boy Advance emulator?

Sorry, at the moment we do not have a GBA emulator for PocketSprite. In theory, someone could try to port one over, but looking at the requirements (mostly memory-wise) for such an emulator, we do not think one will be ported anytime soon.

How long does PocketSprite take to charge?

PocketSprite should take about an hour and a half to charge when the internal battery is entirely empty.

Is it possible to add an NES emulator to PocketSprite?

Yes, and the latest version of the firmware supports an NES emulator!
The text is more than likely too tiny to read for some games - but it does work.

How do save-games work?

When the device is shutdown, the game state and game SRAM is saved in snapshot form on the device. This allows three things:

Where are the products dispatched from? Will there be customs charges?

PocketSprite will be shipped to backers directly from our Hong Kong-based logistics provider. Typically, the monetary value of the device means that it will not be subject to customs or import duties, but this is subject to your country’s regulations.

Is it too small? Does it hurt to play?

We invested a lot of time, money, and testing to ensure that the device is very playable and comfortable. There were several iterations of button style, height, feeling, and material to ensure reliable and comfortable gameplay. The button mechanics are chosen not to be too hard to press, and the buttons themselves are rounded on the top. While everyone’s fingers are different, during development and testing of the software and hardware, we never had any issues with painful fingers.
