I recently got a PocketGo V2.1. But before that, I wanna talk about the first system I got from BittBoy--- the Bittboy Version 3.5 console.
The Bittboy 3.5, that- I will just be calling 'Bittboy' from this point onward, is a small, Gameboy-like open source console that basically emulates many systems and has a few game ports such as Doom, Wolfenstein 3D and such on it. It uses a MicroSD card for storage. I also upgraded the base firmware to MiyooCFW. This is a common, suggested upgrade. I did not use the base firmware much so my usage is based on using this firmware in this review!
The BittBoy at first glance appears to be a Gameboy like device. It's small, It's basically 5 inch by 3 inch in size. It has a d-pad, four main buttons, and two sub buttons for select and start. It also has a system button just under the screen.
It feels good in the hands, and fits in my pocket easily. This has become my 'go to' when I need to go to a doctor's appointment to tool around with and play.
It plays quite well. It handles everything up to the Gameboy Advance just fine.... though Super Nintendo speed will depend on the game. Out of the box on the firmware, I had access to an Amiga Emulator, Gameboy/Gameboy Color emulator, NES, SNES, Master System and Game Gear, Colecovision, Sega Genesis/32x/CD, Atari 2600, Atari Lynx, PC Engine, MAME Arcade, Neo Geo, DOS/PC x86, Pokemini, Wondeswan, PS1, Vectrex, MSX. There's also many game ports available such as Doom being the primary one I use.
I had wonderful experiences with the Gameboy, NES, Master System/GG, Sega Genesis/CD, Atari 2600 and Lynx, and PC Engine, Pokemini and Vectrex emulators. They all ran super great and at 60 FPS for most of the time. I had less than pleasant experiences with the other emulators. Either due to the lack of buttons, the speed at which the emulator played or lack of things that worked right, such as the 'virtual keyboard' in the MSX emulator.
The battery life is decent enough, and hasn't died on any of the outings I've taken it on, but it had drained pretty much too according to the meter on the screen. Also, there's no dedicated volume or brightness buttons- you need to use a key combination to either change the volume or screen brightness.
Overall, if you're looking for a small, cheap little pocket device to play some classic games, this is good. If you're looking for a powerhouse to play SNES, Playstation and the like-- look for something else... perhaps the PocketGo V2.1 I'll review next time!
