description: How to create RAM disks for using old DS homebrew with TWiLight Menu++
---

Some DS homebrew are incapable of properly accessing the SD card filesystem. Because of this, it may be necessary to load a standalone filesystem into the RAM containing the necessary files for your homebrew in order for it to work.

The software used here requires the Windows operating system.

You do not need to follow this if you're using a flashcard.

To make a RAM disk, download [Dataram RAMDisk](https://web.archive.org/web/20240923165935/https://memory.dataram.com/products-and-services/software/ramdisk#freeware) (click `Download Software`), and follow the instructions below.

Instructions by Dakkon7, modified by Rocket Robz:

1. Run RAMDisk
1. Click **View** -> **Advanced**
1. For **Disk Size**, type `12` for DSi, or `28` for 3DS, above **Max 1023 MB**
1. Un-mark **Create TEMP Directory**, if it's already marked
1. Click **Load/Save**
1. Click `Start RAMDisk`, and a new window for your .img should appear
1. Place any file and/or folder the homebrew expects there, and/or file(s) you want to use
1. In the RAMDisk program, click `Save Disk Image Now`
1. Save `romname.img` to the `ramdisks` folder in the .nds file location. If it does not exist already, create it
1. Click `Stop RAMDisk` when you're done
1. In TWiLight Menu++, open the per-game settings for your homebrew
1. Set RAM disk to 0
1. Launch your homebrew, and it should read your RAM disk

If you wish to use the other RAM disk slots for a single homebrew application, use the `.img1` extension for RAM disk slot 1, and so on.
