Halo nds rom

I just recently hacked my brother and I’s ds and we were trying to battle each other on the Pokemon black and white roms but nothing happened. Can we do any kind of local play with nds roms or is that impossible?

Does anyone know if there's a simple 3DS emulator where all you have to do is just load the rom and cheat code files without needing to decrypt the rom files like the DeSmuME NDS or VisualBoyAdvance GBA emulators? I might've overlooked one or two, but I swear I searched everywhere, and I may just be dumb, but the Citra 3DS Emulator is too confusing to me even with looking up guides.

Attached are images of the box, cart, and microsd out of the cart, along with a video of what my problem is
I bought one of these off Amazon a while ago. I had no issues running it with the initial data. I downloaded NDS, GBA, GB/GBC roms off a few sites, loaded them onto the cart, and it still worked. The games played perfectly fine.
A couple days ago, I downloaded more DS roms for some games I wanted to try and put them on the microSD same as always.

1. Download the roms from a site I've used this whole time and trust
   
2. Extract the files if needed
   
3. Rename the .nds rom to have a less cumbersome name
   
4. Put the .nds roms on a USB stick that I've also used this entire time
   
5. Insert the USB stick into my other computer, as it has an SD card reader
   
6. Transfer the microSD from the DS cart into a microSD Adapter
   
7. Insert the adapter with the microSD in it
   
8. Open the USB drive and SD drive on the computer
   
9. Transfer the .nds roms into the appropriate folder
   
10. Eject the USB, take out the microSD adapter
    
11. Transfer the microSD back into the DS cart
    

This method worked perfectly since I first got the 208 in 1 cartridge. It suddenly stopped working after my most recent transfer of games.
I have cleaned all contact points and such with isopropyl alcohol and pressurized air.
Please assist?

Shlooters and Metroidvanias aren't the only genres of games that I play, but they are my favorite.
I have every Borderlands game (including Wonderlands), and I have all of the DLC for each. I also have Outriders, but I don't have any DLC for that game. I played Destiny 2 for a few seasons in the past, but I play Destiny 2 very casually, and I haven't played Destiny 2 in a while.
I have Bloodstained, which finally has a co-op mode (at least, I think I read that news correctly). I also have Terraria, Starbound, Noita, and...I guess Minecraft counts? I usually prefer to play super hostile maps. I loved the GBA and NDS 'vanias, and I also loved CV HD, so I'm hoping that Bloodstained co-op will be amazing.
I have some other games from my Steam library that I've put a lot of time into; Payday 2, Vermintide 2, Divinity: Original Sin II, Deep Rock Galactic, Mercenary Kings, No Man's Sky, and Risk of Rain 2. I'm not really interested in playing TF2, Halo (the MCC), GTAV, or Warframe, but I have those games, too.
I want to make it clear that I'm a reverse engineer. I reverse engineer games for fun, and I've also done it for money a few times. I made the co-op mod for Jet Force Gemini, and I'm the reason custom lobby actions exist in Phantasy Star Online II. I tend to break everything I touch, and I love it. If you're the sort of person that likes being challenged, you're not going to enjoy playing with me - I will find some way to break whatever game we're playing (or...I already have). BG3 is on my wishlist because of how cheesable it looks...and also because of Shadowheart, Bae'zel and Karlach.
I'm also completely over my sweatlord era. I'll play whatever game at the highest difficulty with you - I kind of dunk on Borderlands endgames/Payday 2 DS OD/Vermintide 2 Legend Twitch/DRG Haz 5 (sort of, lol) - but I really don't want to play PvP. My Internet connection is bad, my reflexes are bad, and I'm not really surprised that my reflexes are bad, because my disability has progressed quite a bit within these past few years. I regularly whiff inputs when my hands twitch, and I regularly need to take my hands off of my keyboard so that I can deal with my chronic pain, which is a great way to get my characters wrecked by unfair CPU opponents (and, of course, other people). Conversely, if you want to turn the difficulty down until we feel like we're playing Yoshi's Woolly World (neat game btw) then I'm cool with that. I played Animal Crossing back when I could afford console games, and I found it enjoyable. We could always chat to keep things interesting if the game we're playing is not very demanding...
...but, fair warning, before anyone invites me into a voice chat: my voice might be discomforting. I've been told that it's feminine, I've been told that it's not...I don't know what it is.

Can anyone tell me what the default download path is? I saw another post saying it would go straight to the /roms/NDS folder for twilight but I looked there and I can't find it.

I just got a new SD card because the stock card corrupted then bricked within a week of owning. I no longer have access to the Bios files of the stock card How would I go about getting a compatible set of BIOS for muOS?
I have currently put BIOS files from the tiny best set go, Into the BIOS section on the new SD I also have NDS games (Mainline Pokémon Games)I want to play but the tiny best set go doesn't have NDS roms or BIOS
Any Help Is appreciated thankyou!

I had a stock os in a 64 SanDisk SD with a couple of games and i only use it when i have break at work! Yesterday i play couple of minutes and close it return after a while to found out that it's not start (battery was full). I read the card and found out that have a broken folder in ROM section and some kind of safety lock. Now i have to start all over from the beginning, what OS should i try this time?
I had stockos because was very easy to setup up and very easy on use but that was the 3rd time that i have to fix it because its breaks down out of nowhere and now it destroys the card to.
Also there any chance someone point me to something that can play psp or nds games?

I downloaded this Ōkamidon ROM, and I'm not sure if it's a kernel problem or a ROM one. Is there a way to fix this?

What retro handheld options are there for NDS emulator? Is there something considered "the best"? (No AyaNeo pls, thats too expensive and I already own AyaNeo Air)
I have Trimui Smart Pro and playing GBA on it is a blast. So I'd love to have dedicated devices for NDS and GBC as well.
Thanks!
Edit: I'm mostly gonna be playing Pokemon rom hacks on these devices.

I’m trying to patch soul silver with the storm silver rom hack, I’ve tried several browser based patchers but they always give me errors, I made sure I’m using a .NDS file and the correct patch file but I just keep getting errors. Wonder if anyone has had success patching soul silver on their phone, I don’t have access to a computer unfortunately.

I noticed that no Pokémon games up to GBA except Sapphire have European language support. There are (USA, Europe) games listed, but those doesn't actually have En, De, Fr, Es, It language like .nds roms! Each language have its own ROM.
I am Italian and want to master those games in my language. I love english and usa language but love reading dialogues and attacks in my language. At least for the "third" games (Yellow, Crystal, Emerald) and Red & Fire Red.
Thank you.

With Delta I’ve finally gotten back into playing my GBA and NDS favourites from when I was a kid/teen. It’s a great throwback, especially for all the old Pokemon games that I haven’t played in over a decade.
Soul Silver being at the top of my list, but goddamn the time it takes to grind levels was lost on me when I was a kid.. Had to go with my faves tho for the nostalgia.
Post your Pokemon teams from Delta play throughs and I will rate them without any reasonable rubric.
(Also taking recs for player made roms since I’m new to this)

I have recently installed Onion OS and the Tiny best set and noticed all the ROMs for the NDS end in a .7z extensions. Am I missing something as I’m unable to find any .7z extensions on the Rom websites, only .zip etc.

Do you guys have recommendations for ROM hacks that just have QOL updates like being able to complete the dex without trading ? Not looking specifically for a higher difficulty or Pokémon from newer generations. Other recommended roms are definitely welcome too!

Does anyone know how I set up delta to play NDS roms??

Hello everyone, I have a problem with the "GBA" and "GBC" emulator with Onion OS. Both do not emit sound, no matter which ROM. With the "NDS" emulator there are no problems. here everything works perfectly. what can it be? I have already installed the latest version of Onion OS via the update tool.
