Honestly this is what i was looking for. A full walkthrough of Gamma OS on Anbernic RG405M. Almost most of the KZbinrs waste half of the time line up in installation and very less time on in-depth walkthrough. This is the first video which satisfied my need. My unit is yet to arrive and this will be my first retro handheld i have ever owned. I am Just super excited and watching all the videos about performance tweaking and UI experiences and adding them to a playlist. So that when i have the device I don’t have to waste my time figuring out how to use it like what i did with my first DSLR 😂. Thanks bro.

[@PhyrexTechs]

You’re Welcome!. So far it has been a great device. If you run into any issues while setting it up or have any questions just let me know.

[@mediacenterpc1]

Exactly what I was looking for. Straight to the point and no BS.

[@melodieleblond-champagne8478]

Hey there! I just wanted to take the time to say a big thank you! All your videos have helped me so so much in setting up my RG405M as a total newbie! You're amazing!

[@PhyrexTechs]

Glad to help. Thanks for the kind words!

[@melodieleblond-champagne8478]

@@PhyrexTechs I am running into a slight issue. I am trying to play so DS games, and the screen shows both DS screen all at once. I'd like to set it up so I can toggle between the two screens with R2 let's say, but I can't seem to find how to do it. Right now, when I press R2, it switches between the top and bottom, but both still on the screen. It's a bit hard to explain. Is there anywhere in the settings that I can go to set it so it's full screen with one screen displaying only and a button to click to see the second screen? Thanks!

[@melodieleblond-champagne8478]

Nevermind! Just found out how!

[@PhyrexTechs]

@@melodieleblond-champagne8478 Awesome! Yeah, it can be a little confusing at first with all the DS hotkeys but once you learn them and get used to it, it works great.

I got my RG353P yesterday and have been toying with firmware. GammaOS surprisingly gave me the best performance all around. RockNIX was ok, but wasn’t nearly as smooth. I think I’ll be settling on GammaOS.

[@AdonisPointer]

Thank you! This video was simple and direct enough to finally make me want to try it... and it worked! :) RG505...

You're welcome! Glad it worked for you.

[@Daiarthaine65]

Great video. I just ordered my RG405M and I plan to install GammaOS on it right out of the box. This was a great rundown of the features, as I am a total newbie to this. (Not to custom ROMs, but I haven't touched Daijisho before.)

[@PhyrexTechs]

Awesome it is a great device and GammaOS really makes it shine.

[@tombrown819]

Great video! I have my RG505 perfectly set up with GammaOS thanks to you! Some emulators need Bios files - (I think) I found where to put them, but read somewhere that they need to be named in a certain way. Do you have a list of what I need to name the Bios files for Retroarch on GammaOS?

[@PhyrexTechs]

Great to hear! Yeah if you need to check the bios file name this is the best place. docs.libretro.com/library/bios/

[@ziff23]

Trying to figure out how to map keys for native android games. Is there a setting that I need to trigger?

[@philkab6914]

Thank you so much, you helped me a lot with your videos. Flashing Gamma OS, unblocking it, flashing again (because wifi wasnt working, now it is!) and now this. Just one thing I can't seem to make work: the switching power modes. When I keep the 3 buttons pressed nothing is happening. Do I need to do it from a certain screen?

[@PhyrexTechs]

Yeah so after the update to Gamma 1.5 they removed the button combos to switch modes. The way to do it now is the Android quick menu. You can open it by swiping down from the top of the screen. One of the options there should allow you to cycle through the modes.

[@philkab8545]

​@@PhyrexTechs Oh, actually I prefer that over the button combo. Had that option existed before 1.5 in parallel to the button or is it a fully new substitute?

[@PhyrexTechs]

I'm pretty sure it was in version 1.3 at least on the 405m version.

[@leunaum]

Does everyone get the long boot Anbernic logo plus that message on the side every time one power on their 405 or 505?

[@PhyrexTechs]

I just used a stopwatch to get the exact times. Starting when I hold the power button down to power on it takes about 27 seconds for me to get to the G boot logo and a total of 50 seconds to get fully loaded including Daijisho. You will always get that Info and Warning message on the side because we unlocked the bootloader to install Gamma and that is fine to see.

[@im_awesomeee]

Thank you for the video ❤ but i have a question.. How i can go back to the first launcher,when you buy tje system and you turn on tje console:D

I finally got gamma os working on my device, now I gotta figure out Wich core to use for each system. I started with miyoo mini so all this new stuff is completely foreign. Do you know a site I could visit to find the perfect settings to get my rg505 up and running?

[@PhyrexTechs]

Most of the default retroarch emulators should be good. The ones you are going to want to download manually from the playstore/sideload are PPSSPP, Dolphin, NetherSX2, and maybe M64Plus FZ

[@KATORZYN]

Do you have any advice if i install gamma os and games from wii, gamecube, ps2 dosen’t work. If i select another emulator in options then it says „this emulator dosen’t exist on your device” please help

[@PhyrexTechs]

You will need to download/install the standalone emulators for those systems either from the Google Play store or for .apk files.

[@cantaldianebernadetteo3256]

hello why is there no 'new widgets' option on my widgets tab. im using rg405m gamma os. please help

[@PhyrexTechs]

Never seen that before. If you hit R2 should be the shortcut to create a new widget when on the widgets screen. Does anything happen when pressing that?

[@user-eg9sx3oo9u]

Can this tutorial be used to install this on the 405V?

[@PhyrexTechs]

You can use my install guide for 405V : kzbin.info/www/bejne/jWS0g4OPfdKij5I Just make sure that you click on the correct link in the description for the RG405V and be aware that because that one is still in beta fan control does not work for it.

Hey maybe youncan help me out gamma os has a white screen on Gameboy not the original look i cant seem to figure out how to change it the settings are different from your latest video on overlays and stuff. Thx

[@PhyrexTechs]

I think you can fix this by: going into retroarch quick settings go to core options Set GB Colorization to "Internal" Then you can use the L and R buttons to cycle through all the colors.

[@solomonkane408]

@@PhyrexTechs worked like a charm brother thank you . One more I cant seem to add a border like the ot Gameboy I followed the guide for onion but can't find the settings .

[@PhyrexTechs]

It's gonna be a little different with the rg405m. Not sure if it comes with any stock overlays. However, the drkhrse pack from my overlay video does work with it. What you will need to do is: Put the unzipped drkhrse pack folder into the Retroarch folder on the internal memory or on your SD card. Then go into the Retroarch quick menu and select On-screen overlay and you may have to enable display overlay. Then go to overlay preset and keep hitting "parent directory" until you see an option that says /storage/emulated/0/Retroarch Or if on a SD card /storage/(random letters and number) Select that and you should see the drkhrse folder.

[@adrianpadilla2200]

Just downloaded. But I need to re install the other emulators for ps2, will, n64, gamecube, and 3ds. And having a problem trying to put my SD card file in the emulators won’t show up

[@PhyrexTechs]

Normally when I try to add games to stand along emulators, after selecting "add games/add folder" You are able to tap on the 3 line menu in the top left then select your SD card from the Open from menu. Then just navigate to where the roms are located and select "Use this folder". Where are you running into the issue? Does your device detect your SD card at all? Can you check the Files app to see if you are able to see your SD card?

[@zacharymorgan9974]

If I use L3 and R3 it brings up the retroarch menu, but R1, L1 and R3 don’t bring up performance mode options, and the Xbox controller scheme doesn’t work either :(

[@PhyrexTechs]

Do you have the latest version installed? This may have been one of the changes made in 1.5.1. Patch notes say everything is now changeable from the android quick menu when you swipe down from the top of the screen. I'll have to check later if I can still do it.

[@Vngel-TV]

Just received my RG405V and installed GammaOS buttt, my battery has been stuck on the same percentage for over an hour. What is the fix for this?

[@PhyrexTechs]

Sorry for the late response. The best way to make sure the battery gets synced up properly is to charge your device fully and drain the battery completely. After a couple cycles it should be pretty accurate.

[@Vngel-TV]

@@PhyrexTechs I ended up sending the RG405V back and just getting the Retroid Pocket 4 pro :P the screen was bothering me too much.

[@xkiller2kx547]

Can you do this but with a 405 v

[@PhyrexTechs]

Sorry, I won't be able to as I do not own the 405v. However, if you have installed Gamma OS everything should be the same. If you are needing to install Gamma OS my video for that works for the 405v also.

[@kylesimpson5331]

How do i get rid of the screen lock. I need a fast jump into games experience. My Miyoo minni is great at this.

[@PhyrexTechs]

To turn off the Android screen lock you will need to go into the Android settings then Display then in Lock screen you can disable the lock screen completely. Also in Display you can set the time idle before the screen timeout.

[@antongripak1735]

the video is awesome. I just got my rg405m and installed Gamma OS. Everything is fine but I can't run PSP and PS2 games. 1. With PSP I click the game and the screen blinks and I see the games list again 2. With PS2 I click and the screen is black. Nothing happens. I click B-button and in some seconds it says that Retroarch doesn't respond. I tried 4-5 games. Also tried another player from the list (not Retroarch) downloaded it and the game ran, but the buttons don't work and there are controller elements on the screens for touchscreen play. Can anyone help me with this? Thanks

[@PhyrexTechs]

So Gamma OS uses RetroArch for all systems by default. However for PSP and PS2 Retroarch is not great and I always have issues. I would recommend downloading standalone apps for those. If you use the Google Play Store I would recommend PPSSPP and AetherSX2 for those systems. You can then set them as the default App in Daijisho doing what I show at 3:18.

[@antongripak1735]

@@PhyrexTechs thanks for help. I already uploaded AetherSX2 and it works. But is there a chance to set the control from the touchscreen buttons to phisical Anbernic buttons?

@@antongripak1735 Yes you can. First go to the controller settings. In the Touchscreen Tab disable "Touchscreen Controller View" Then go to the Controller Port 1 Tab Select Controller Type and set to DualShock 2 then tap automatic mapping and it should set everything.

If they are for retroarch you will want them in the systems folder in retroarch. If you are using a SD card you may need to go into the retroarch directory settings and change the bios location to point to your bios folder on your SD card.
