An older Retro Handheld Console, but still decent especially with OnionOS custom firmware.
Another alternative with the same form-factor would be the TrimUI Brick, but it's currently a lot more expensive.
Specs:
- 3.5" IPS 640x480 display
- ARM Cortex-A7 Dual-core CPU
- 3000mAh removable battery
- Vibrating Motor
- Wi-Fi Network Connection - Update OTA and Retroarch Achievements
- Supported format: PS1, CPS, FBA, GBA, GBA, GB, SFC, FC, MD, SMS, GG, NEOGEO, PCE, WSC (and some DS and Pico-8 Games).
I highly recommend installing OnionOS game launcher and replacing the the MicroSD Card with a reputable brand such as SanDisk or Samsung.

Crazy value. Especially when you factor in it can do Ports, Java and Pico-8.
