"DJEmergency" own this device and did an interesting review on it (available on a discord server).
Android system with retroarch on it
source:https://discordapp.com/channels/529983248114122762/597717494802677761DJEmergency's review of the RS-07 V2 (Android) device.Pros
- It?s using a version of Retroarch at the core of it?s emulation.
- The analog stick has it?s own board attached to it so mods can be possible for it. (Maybe replace it with a Sanwa stick and 3D print a larger bottom case.)
- Most emulators runs at a solid 60FPS. (I provide test results below)
- Android! Possible to root the device in the future or add our own APKs. (Plug the device in a PC using the top USB port, Hold the RETURN button, and power on.) Just need drivers for it .
- A few hidden emulators.
- The screen is clear and great with most angles. The brightness can be adjusted at your leisure.
- HDMI out with 720P
- Stereo Headphone jack.
- Micro SD Card slot.
- 2 USB ports.
- Videos run solid! No slow downs.
- Comes with 2 gamepads and supports up to 2 players. (Possibly four, but haven?t tested it with a USB hub)
- Rechargeable battery.
- The speaker is nice! Sounds better than the RS-07 Arcade Mini and has a bit of low end to it.
- Analog stick dead zone is very small with emulation , but in the system menu it?s bigger.
- Save states!
- Controller mapping! (Systems like the NES and SNES needs the A and B buttons swapped.)
- Battery saves work!Cons
- Sound on some emulation can be a bit distorted.
- I think it?s running an older version of RetroArch.
- The hidden emulators doesn?t run well.. (I guess that?s why they left them out in the supported system list.)
- Battery runs between 3-4 hours. (Not really a con for me but others might think so..)
- Buttons and analog stick can be a hit or miss sometimes within the main system menu, but it?s perfect with emulators.
- Once in awhile the controls stop working when switching to a different emulator. Powering off and back on the device will fix the issue.
- Some people reported missing ROMs in their device.
- Some devices were shipped with the RS-12 gamepads (Like mine)
- The file list order can be off so you might have to do some digging with the file you want.
- Holding left or right to skip pages of files do nothing.. You will have to continuously tap to change the pages.
- There is no graphical settings.. All games run stretched with some blurred filter. (Maybe possible to change, because I found a settings file on the micro SD card that came with it.)EMULATION TEST RESULTS
GBA: Almost perfect! Some games like Astrerix & Obelix XXL and Need for Speed Underground (3D games with polygons that push the GBA?s limits) are playable while sound can be choppy. For the most part everything runs smooth with a solid 60 FPS.
GB/GBC: GB Emulation is great. Few games have graphical glitches like Toy Story Racer. Some sounds seem to be distorted but not too bad. Games that use the Super Gameboy features will work too!
NES: Almost perfect! Runs anything I can throw at it! The sound seems to have pops at the end of notes though.
SNES: Almost perfect! Sounds sometimes have pops at the end. I tried some of the more demanding games and the results are pretty good. Dirt Trax FX is one of those demanding games that I always like to test. This device can run it at a playable state. The sound is a bit choppy, but it?s still playable! Star Fox runs smooth, but the sound has a lot of pops in it. Stunt Race FX and SMW2 runs near perfect!
GG: Almost perfect! Very few games have graphical issues. I would say it?s around 99% there!
Gen/MD: Almost perfect! It can run anything I can throw at it. Race Drivin? runs well.. Virtua Racing runs smooth, but the sound is a tiny bit choppy and for some reason I can?t start the game.. Other games are near perfect
PS1: This runs fairly well! Many games work with it, but some use frame skipping to keep it running smooth. Still very playable and fun!
CPS1/CPS2: Emulation runs well. Some games have graphical glitches.
MAME: Some work and some doesn?t you will have to test games. Pac-Man, Donkey Kong, The Simpsons and TMNT games run at 60FPS.
N64: It?s very slow with most games and the control mapping doesn?t seem to work properly. Anything that needs the analog stick is no good. You might have a better chance with 2D games, but even that is slow..
PCE/TG16: Slow and control mapping is broken.
