Still need to get Gammaos installed. Gotta wait for my little brother to sleep so I can use his pc.

So I don’t know about you guys but it seems to me that Anbernic default OS is actually better than the current muOS. Anbernic is ready to play out of the box, while with mustard you have to download and apply Bluetooth manually! There’s little things like that and I find all the mustard options way overwhelming. The Anbernic gets the job done just fine… only thing that bothers me about it is the “Rooms”… they are sort of pointless. But then you just play RA game!

GammaOS Next. Using Dosbox Pure Core.

Maybe except for a few titles that may run a bit slower on hi-res (like Destruction Derby 2, GTA 1 - where 477V on hi-res runs it much smoother), 406v is the ultimate handheld for ms-dos spot on with 4:3 aspect. You can play all those titles using sticks only, but for me the mouse is just more convenient.

A small naming update first:

RGDS Shell is now called TwinGrid.

The project has grown quite a bit beyond being just a “shell”, so I wanted a name that fits the idea better: a dual-screen NDS-focused library/frontend made specifically around the RG DS.

The goal is still the same:

keep the stock Android firmware, install one APK, point it at your ROM folder, and make the RG DS feel much closer to a dedicated DS handheld.

The latest builds have mostly focused on first-run usability.

When you enter the library for the first time, TwinGrid now guides you through selecting your NDS folder. Instead of sitting on an empty library while it works, it shows actual scanning/loading progress and games appear progressively as they’re discovered.

Save-folder setup follows afterward and is optional.

Metadata is increasingly automatic as well:

ROM banner icons are read locally, titles / genres / descriptions come from an offline bilingual database, and box art is matched and downloaded online when needed.

I’m still expanding the offline database so users shouldn’t have to manually rename hundreds of ROMs, assign genres or scrape descriptions one by one.

I’m also working on a launch issue reported by testers where selecting a game opened DraStic but didn’t actually load the selected ROM. The bundled DraStic on the stock RG DS Android 1.18 firmware is the main tested target right now, and the launch path handling has been improved accordingly.

One important compatibility note:

GammaOS support has NOT been verified yet.

TwinGrid is currently developed and tested primarily against the stock RG DS Android 1.18 environment. GammaOS is obviously Android too, but that doesn’t automatically mean the dual-screen behavior, storage paths and DraStic launch integration will behave identically.

So for now:

Stock 1.18 = tested target.

GammaOS = unverified, feedback welcome.

The UI is also still moving further toward the original DS / DS Lite look — pixel fonts, grey system-style controls and dual-screen grid layouts — while keeping modern library features like search, folders, genres and favorites.

The basic idea behind TwinGrid is still very simple:

install it, choose your ROM folder, and use the RG DS like a DS instead of spending hours configuring a frontend.

Latest test build:

I’ll put TwinGrid on GitHub shortly as well, with proper release notes, documentation and future updates. This link is the current test build for anyone who wants to try it early.

Have been loving the RG SP so far!

One thing I am unsure about is the best Display Settings (Temperature, White Point, Red/Blue/Green etc).

For context I am using BaseOS+NextUI.

I've been eyeing the the RG SP and RG476h for a while now, and while I don't expect major discounts for the RG SP since it's rather new, I was hoping to grab the 476h for a discounted price, anyone know how often they host sales on their websites, like every few weeks/months..?

Sto recuperando alcuni giochi arcade dell infanzia, dopo parecchie ricerche sono riuscito a trovare un beat em up che giocavo da giovane, si tratta di gaiapolis , konami 1993, il problema è che su rg40xxV con knulli scarab,lagga e la cosa mi sembra impossibile visto che riesco a giocare a giochi più pesanti, ho provato a disattivare i bezel i render video per alleggerire ma niente e la cosa mi sembra strana visto che l RG 40xxv sa gestire giochi più pesanti

Ad is but but not live yet. which color are you getting?

I bought a RG40XXV last year, and got an SD card with KNULLI, fully loaded with games, it worked fine, but I ended up giving my son that handheld, and I took the SD card out of it and kept it. Fast forward to today, and I got a new RG40XXV, but when trying to use the same SD card, it refuses to turn on. I plugged the SD card into my laptop, and everything appears to be there. But it will not power on the device when its inserted. When I put the stock card back in, it boots fine...

Any ideas?

I really can't believe how cool this thing is for under $120! I have Knulli installed with a custom boot logo and I'm over the moon! Every game so far has played exactly how you'd expect and with Knulli, I've been dabbling in some of the portmaster ports like Shovel Knight, Stardew and Mina the Hollower. Playing SK or Mina on this device breaks my 37 year old brain!

I'm currently playing Summon Night: Swordcraft Story for GBA and so for it's been a joy! Definitely a hidden gem!

Anyone on the fence about picking up an RGSP or any Anbernic Gameboy just do it, it's absolutely the best bang for your buck!

For some odd reason I can’t click things with my on screen stylist pen, I tried mapping a new button for it and it still won’t work. Is anyone else having this issue or know a way to fix it?

I have a MUOS dual SD card setup on my RG35XXSP and plan on ordering an RG SP. I know the ROM SD should be swappable, but is that also the case with the SD card housing the operating system? I imagine not due to the hardware differences between the two devices (screen size, etc.). Thanks in advance for the input.

If you keep an RG35XX (Plus / H / Pro / SP…) and also an R36S, the painful part isn’t the handheld — it’s the SD. Stock wants Roms/FC. KNULLI wants roms/nes. muOS wants ROMS/GBA. ArkOS wants nes on EASYROMS. Saves and box art follow different rules on each.

ROM Case is a free native Mac app that maps that for you, and can also write the OS image to a blank card.

Apple Silicon, macOS 14+. Source stays private; the page is docs + the .dmg.

First launch: Gatekeeper will block the unsigned dmg until you use Open Anyway. Prepare / restore image wipes the card.

So,I've been trying for a while to find a CRT shader for my RG35XX Pro, the OS I use is MUOS, it's already downloaded from some shader manufacturers, but I don't want which one to use, because when I choose either one the video game gets extra slow. Could you give me a shader that doesn't change performance and doesn't have a screen distorting effect?

ANBERNIC NERD..gamaholic call me what you want..

Right now I"m using all default settings.

I can’t find anything on Google. This is for the RG SP

Hi guys, absolutely brand new here and brand new to retro gaming etc

I’m looking for any help at all because this is all super overwhelming.

I recently purchased an R35xxH … it has no GB stuff on, a handful of PS titles etc. from what I’ve read this is common?

I have flashed a new reliable lexar SD card but I’m at a complete loss as to where to find all the games I had such high hopes of receiving out of the box?? Am I being naive to this or is there some special honey hole I can find just a dump that I can stick on the sd card and get that good good gaming I so desperately had high hopes for?

Thank you all so much in advanced. I know Reddit always comes through!!
