I've seen online people utilizing shaders from Duimon's Mega Bezel pack in order to achieve a sceen gap on the 3DS Citra core similar to the native built in option on DeSmuME core. I am curious if anyone has a tutorial on how to achieve this effect? Thanks!

I’ve been spending hours trying to get this to work. I’ll try to explain everything I’ve done as best I can.

I have 15 Philips CDi games I’m trying to play on android (Ayn Thor) using retroarch. I converted the games to CHD format using CHDMan since I heard the same-CDi core doesn’t work with bin and cue files. I’ve added the cdimono 1/2 files and the bios files onto my bios directory for retroarch. I’ve made sure they’re the correct ones as well. Everytime I try to boot a game, it says “fatal error: required files are missing, the machine cannot be runned”. I’ve tried everything I can. If anybody found a way to fix this, please let me know. I really want to play my CDi games. Thanks.

I'm having an issue running this game on android retroarch where all the textures appear black as seen in the screenshot. I tinkered with the video options but the only thing that fixed the textures made the game lag badly and run at a crawl even in the menus. What settings do i have to change to get the textures working and the game running at the expected speed?

Need help regarding using cheats

I’ve spent the entire day trying to figure out how to trade pokemon on Retroarch on IOS and finally found out that I can’t use TGB Dual to trade pokemon between Red and Blue on my iphone from one ROM to another. However, I can figure out a way to be able to control the second screen without an external controller. I’d ideally like to be able to swap which screen is being controlled, so I can swap from screen one to screen two and vice versa. If that isn’t possible, being able to control them at once would be nice.

I tried Latest Stable and Nightly Versions and same issue happens

Load up game and just Freezes Straight away with White Screen

Using Windows 11

Hi there im very new to retro arch using it for gba emulation how do i edit screen layouts and add and remove buttons i want to add a reset button for shiny hunting in pokemon im using samsung z fold 8 ultra thanks fam

Is there any way you can redirect the data/install files of where Retroarch is located? That way if you delete the app, or something happens to it. You can start it up and redirect it towards the files for it to work and have the old settings. Or if you want to move this stuff to a new device, and you don't want to go through the problem of messing with new settings all over again.​

Like you can do with some emulators. Like with Dolphin, vita3k, armsx2, armsx3 and ppsspp.

So, I have an Xbox controller which I'm using to play Conker's Bad Fur Day, it has been mapped, even with the exclusive C buttons option but every time I press B it, not only hits with the pan, but also goes to a "first or second person" view kind of thing(?). The control mapping shows the B button as B only and C buttons are X,Y, L3 and R3. Does anyone know how to fix the issue or which is exactly the issue?

A little more context, if I interchange A and B then I jump with B and it doesn't go to the close view, but if I press A and then B it hits with the pan (A button) and then the camera comes close to the second person view.

I hope I made myself clear enough.

The new EMIR Core which is the Core Made from YMIR Emulator

Only see its for Windows version so wondering if be added to AppStore/TestFlight and other versions

I have android retroarch on a softmodded arcade1up with a bluetooth keyboard attached and when I go to explore-search name to find a title certain keys trigger other stuff. I'm looking for some kind of option that suspends whatever other key binds are in place when using the search function beyond using the on screen keyboard

I’m playing Pokémon emerald on a phone and I’m trying to complete the Pokédex is it possible to trade Pokémon if I have retroarch on another phone? And when I look it up, I see conflicting information.

I'm using the dolphin core on retroarch to play Super Mario Galaxy 2, I have binded all of the tilt controls, I'm using the mouse for the cursor and I'm using a Switch Pro Controller for the controller— but even then I simply cannot figure out how I make this stupid ball stop moving forward on its own!

The same thing happens with the flying minigames or minigames that require tilt controls. Someone, please help me!

The screen keeps being black and I don't know how to fix it.

My phone is an Android, and is a Samsung Galaxy S25 (SM-S931U) by the way. This save file comes from a previous phone I had, that was tramsferred to this one.

Im trying to properly set up an 8bitdo m30 controller but am have hit a brick wall. I have followed all the directions that google ai provided and have read a bunch of reddit posts but to no avail.

No matter what setting I change I cannot get to an option to select 6 button gamepad.

Any advice?

Been playing through Dawn of sorrow on MelonDs ds before I started using runahead and found runahead is disabled in latency setting which is a bit annoying. Downloaded the MelonDs core which is apparently the older one and it does support runahead? Any reason why it was removed?

I'm trying to add cheats from this into my pokemon emerald in retroarch: https://www.reddit.com/r/Gameshark/comments/1d30quy/buy_any_decoration_at_slateport_market_in_pokemon/

When I turn them off again though, the game menu appears and won't close, or the game just crashes.

It's happening again. I was redownloaded RetroArch on a stabled version, then I've changed the menu driver to xmb. Moments later, the menu looked like... I don't know to put my words on my menu. How can I fix this?

Hey :)

tl;dr: NDS ROM not able to boot up on RetroArch but same ROM is working on standalone emulators and 3DS. All other NDS ROMs/games I own are (still) working normally.

I have tried to play Yu-Gi-Oh! 5D's World Championship 2009 on RetroArch on Windows 11 but very time I try to start it up everything get stuck at beginning and RetroArch crashes (sometimes after a few minutes freezing, sometimes directly). I tried all Cores for NDS games but all the same. Even redumping the ROM file on my 3DS didn't work out.

The ROM is working perfectly on standalone Emulators like MelonDS and DeSmuME and on my 3DS.

I noticed something weird that could be relevant for the problem. Because sometimes my RetroArch is suppressing my microphone. I'm not able to produce input on testing (noticed because I was in Discord with friends).

Could be irrelevant but maybe it's important.

All other of my NDS ROMs work perfectly on RetroArch.

On RetroAchivements it shows I played Yu-Gi-Oh! 5D's 2009 but I could not load into the game a single time.

Never had any problems with NDS ROMs before on RetroArch, so I have no idea what else I can try to fix it.

I don't want to lose all my settings, thumbnails etc with reinstalling RetroArch completely if not necessary but I really want to play that game on my PC again.

It tired a lot different settings yesterday without any changes. Even DS bios files didn't change anything.

Any other ideas what else could be wrong and how I can fix it?

I believe this is called "hacking the kernel" and I can enable it on rgui driver, but on ozone there are only 4 themes: basic black (default), basic white, nord, and gruvbox dark.

Windows 10.

Have been getting into Retro Achievements lately, so, trying to go back to old games from childhood. I saw in the FAQ that LRPS2 is supposedly in pretty good shape, but, it's giving me some trouble, and I'd like to see if anybody might have some obvious ideas on a fix.

Specifically, issues are popping up for NFS Most Wanted - Black Edition on LRPS2. I'm getting a weird graphical error where the textures of nearby cars, the map, or the save icon, will overlay on top of the screen with opacity that seems to change randomly. Opacity ranging from "annoying, but playable" to "It's literally just a black screen with HUD elements on top".

I already got the GameIndex from the automated updater, but, I went and got the one manually from the github to see if that would make a difference. Also tried changing the renderer around, but, didn't have any effect. I did end up getting a CTD earlier when messing with settings, but that went away after resetting the core to default. Figured I'd see if anybody had any insight into any obvious causes for this.

https://pastebin.com/7diVUYZX - Log for a single race where issue occurred.

After experimentation, it looks like the issue is even worse in Carbon. So, it's something to do with this same engine.

Reposted because of poor word choice in previous post that automod didn't like.

It started as a personnal project, you see I love old PC games, I collect good old big boxes but settings up dos games has always been a pain in the ass lol

So I started working on this, which basically automates almost every painful steps of dos emulation

Basically you can add a rom you own in any format and ROM90 will automatically detect it and install it properly on either DosBox pure or ScummVM https://rom90.com/

I've also added a few well needed comfort features :

- Quick resume

- Universal save/load shortcuts

- Fully fledge save state manager

- Keyboard remapping and controller support

- Export options and batch exports for people to share properly their collection

and many more small QoLs that makes Dos emulation almost as easy as most console emulator

I also made a discord, if people need help or want to share their experience, gameplay, tips or collections

I'm a bit nervous showing this to all of you I hope some of you will find it useful, feel free to ask me anything

I'm trying to get Sharp X68000 working in RetroArch on Android, but I'm completely stuck and need someone to explain it to me like I'm five.

Here is what I've done so far following YouTube guides:

- Downloaded the PX68k core.

- Created a folder named keropi inside /storage/emulated/0/RetroArch/system/

- Placed iplrom.dat and cgrom.dat inside that keropi folder.

My ROMs are stored in:

/storage/emulated/0/Download/sharpx6800/

Now I'm looking at the config file for the core:

How exactly does the StartDir= line need to look? Should it be StartDir=/storage/emulated/0/Download/sharpx6800/?

What else am I missing to get games to boot? Any help would be greatly appreciated!
