Hello guys, welcome to my channel.

Today we’re gonna be taking a look at some emulation performance on the Amlogic S805 Android TV BOX with SX05RE prebuild image.

As I mentioned before, what I am using is an SumaVison S6 TV Box, which cost me about 3.

7$, and it’s powered by Amlogic S805.

Its CPU is a quad-core A5 running at 1.

5 gigahertz and the GPU is a quad-core Mali450.

S6 has 1 gigabytes of RAM and 4 gigabytes of internal storage.

My premade image of Sx05RE includes RetroArch, EmulationStation, several standalone emulators, and KODI.

Well, let’s go ahead and get right into it.

With proper emulators, low-end platforms such as NES, PC Engine (including PCE-CD), Genesis (including SEGA-CD), SNES, Gameboy Color, Gameboy Advance, CPS/CPS2/CPS3, NEO GEO (including NEOGEO CD) just run at full speed.

What I’m really interested in here is PlayStation, Dreamcast, Nintendo 64, PSP, NDS and some stubborn Arcade games.

Due to limited performance, and taking into account the graphics presented on the large-screen TV, all emulators run at 720P 60Hz.

Standalone emulators such as PPSSPP and Reicast suffer under 1080P and performance is very poor, while the graphics are poor under 480P or 576P.

First up we have some PS1 emulation.

Most of PS1 games Which are compatible by PCSX Rearmded can run at full speed.

Even compressed in chd format, speed will not be affected.

Some games can run at full speed even with enhanced resolution enabled in the core options.

As you can see here, Winning Eleven 2020 is very choppy with enhanced resolution, so we have to get back to original resolution to get full speed.

If you feel graphics are poor, you can apply the scanline filter and the graphics will look better.

Bloody Roar 2 can not reach full speed even with original resolution.

This game does struggle on low-end hardware.

For Dreamcast games we are using standalone Reicast here.

Unfortunately, the Reicast we use here is rather old and the emulation is very inaccurate.

So we will see many graphics glitches and sound distortion.

However, it’s a fast emulator, and many compatible games run good.

But some games such as Cannon Spike, Dynamite Cop will have severe graphic glitches due to inferior design on GLES2 with Mali450.

The N64 architecture is complex, and emulation for it does struggle on low-end hardware.

Some simple games such as Super Mario 64 can be emulated smoothly with original resolution.

However, most game run very slow, and most of them have graphics glitches.

If you are interested in the technical details about N64 emulation, you can check the video made by Modern Vintage Gamer.

We’re using standalone PPSSPP 1.


4 here to emulate PSP games.

For good performance, we need to change the settings a bit according to the games.

Basically, we can change rendering mode, internal resolution, clock frequency and so on.

Some simple PSP games can run at full speed with 2x absolution.

Many games can only run smoothly with original resolution.

And some games, no matter what me change, just run poorly.

Drastic is a closed source NDS emulator, but there’s an ARM generic version available with SDL2.

Most of NDS games run at full speed here, and many even run at full speed with enhanced resolution.

Of course, some games require automatic frame skip on to reach full speed.

At last let’s check some arcade games.

With FBNeo, most PGM games run with a decent speed.

Some late PGM games run a bit slow.

All shooting games from Psikyo and early CAVE shooting games run at full speed with FBAlpha2012 from Libretro.

For Taito F2’s games, we are using Libretro core MAME2003 Plus.

Some can reach full speed while some can not.

Well, that’s it for this video.

Guys, I really appreciate you watching.

In general, S805 is outdated with A5 CPU, but its frequency is high, so its performance on emulation is not as bad as many people thought.

Since S805 boxes are outdated and developments on it become less and less, probably the performance we have here would not be improved.

As I mentioned in other videos, do not waste your money on any S805 box.

But if you have a spare S805 box in your hands, you may try it for emulation.

If you have any questions, let me know in the comments below.

And again thanks for watching.
