Overview

The RetroMini RS-90, also known as the Subor RS90, is a vertical handheld gaming console released in 2017. It runs an open-source operating system and is designed for retro gaming enthusiasts who want a portable device for emulating classic games. The device features a 2.0-inch TFT display with a 3:2 aspect ratio and a resolution of 240x160 pixels. Powered by an Ingenic JZ4725B processor clocked at 360 MHz and 32 MB of DDR2 RAM, it can emulate systems up to the Game Boy Advance. Storage is expandable via an external MicroSD card, and the battery is a user-replaceable 1020 mAh BL-5C unit. The RS-90 is housed in a translucent black plastic shell, weighing 103 grams, and measures 105 mm x 70 mm x 22 mm. It includes a 3.5mm headphone jack for audio output.

Who It Is For

It's suitable for playing classic games from the NES, Game Boy, and Game Boy Advance era. The open-source OS appeals to tinkerers who enjoy customizing their device. However, it's not for those seeking modern connectivity, high-resolution displays, or powerful performance beyond GBA emulation.

Buying Notes

As a budget device from 2017, the RS-90 may be available from second-hand markets or retro gaming stores. Prices typically range from $0 to $50, with an original launch price of around $30. Ensure you purchase from a reputable seller, and consider that the device uses a replaceable BL-5C battery, which is easy to find. The lack of video output and connectivity means it's strictly a standalone handheld. Check for community firmware updates to enhance the emulation experience.
