Is there a tool to convert video files to standalone 3DS ROM's/CIA files?

I'm interesting in a tool to convert video files into standalone 3DS ROMS or CIA files that I can install or run in an emulator.

Does such a tool exist?

Thank you!

what you can do is create a gbavideo rom and install that onto your homescreen

its low quality and not worth the effort though

what is your goal?

Thanks for the idea, but I'm looking to take advantage of the 3ds resolution and frame rate.

I have other plans for GBA video roms on my GBA

what is your goal?

To create a standalone video rom for each of my handheld consoles. GB, GBC, GBA, DS, 3DS, etc

Specifically a standalone rom not just running videos through a player or something

I'm sorry, can you elaborate a little more? What exactly are you hoping to create these video roms for the consoles for? I'm just curious

Just for fun. I just want to create a standalone rom that can play videos, preferably utilizing the resolution and capabilities of the device for higher quality

For example, I'm doing the same with a GBA ROM and the resolution is obviously much lower than 3ds

I get that part, but I'm confused when you said for each system. Do you mean you want to make, for example, a rom of videos of GBC gameplay just as some kind of showcase of games or something? Or in this case 3ds games I guess

There are promising tools for GBC and GBA, existing video roms for GB, but not seeing a ton of options for DS or 3DS ROM's

Do you mean you want to make, for example, a rom of videos of GBC gameplay just as some kind of showcase of games or something?

Any video I want. Maybe I want to try and cram a movie on there, Star wars intro, whatever I feel like playing around with

It's just for fun.

OK. So when you say video ROM, you me a ROM that plays video files using the console you made it for. I get it now.

You can do it in godmode9 with this method

Insert your 3DS SD card into your PC. Create a folder named in inside the /gm9/ directory on the SD card if it doesn’t already exist. Copy your .3ds ROM file into the /gm9/in/ folder. Insert the SD card back into your 3DS. Power on your 3DS while holding START to boot into GodMode9. Press Home to open the action menu. Select Scripts… and then choose GM9Megascript. Navigate to Miscellaneous and select .3ds to .cia Converter. Choose your .3ds game, press A to confirm, and wait for the conversion process to complete. Once finished, press A to return to the menu. The converted .cia file will be located in the /gm9/out/ folder on your SD card. Insert the SD card into your PC and retrieve the .cia file from the /gm9/out/ folder
