.is1 File Extension

Developer: M3 Sakura
File type: M3 Sakura Real-Time Save 1 File
You're here because you have a file that has a file extension ending in .is1. Files with the file extension .is1 can only be launched by certain applications. It's possible that .is1 files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .is1 file?

IS1 files are M3 Sakura Real-Time Save 1 Files or the data files that are created using M3 Sakura. These are the files containing the game state while it is played and these are also the files that are used to save game snapshots even if saving is not allowed during the time. Apart from the IS1 file extension used to save these files, the saved M3 Sakura slots also make use of ".is0," ".is2," and ".is3” file extensions. The IS1 file extension was developed by M3 Sakura and the IS1 files are categorized as data files. The IS1 files can be opened on a Windows operating system with M3 Sakura. M3 Sakura is a Nintendo DS loader running on M3DS Real and M3i Zero flashcarts. The software was developed by MoonLight and was released officially last May 30, 2008 in Japan. This software is also known for its fast menu, excellent controls, built-in media player as well as other features that make it the most preferred Nintendo DS loader for almost all M3 cart users.

how to open a .is1 file?

Launch a .is1 file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .is1 file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .is1 files aren't yet associated with it. In this case, when you try to open a .is1 file, you can tell Windows which application is the correct one for that file. From then on, opening a  .is1 file will open the correct application.

M3 Sakura

M3 Sakura

Outside of Japan, M3 Sakura refers to the Nintendo DS custom firmware developed by the M3 team in collaboration with Infantile Paralysiser - also known as Moonlight - who is a freelance developer of homebrewed software. M3 Sakura, or also known as Moonshell v.2, was intended for use with DS flashcart products M3 DS Real, M3i Zero, and M3 Sakura (Japan-only release). Usually, a dual-boot bundle comes with Touchpod, which is another DS firmware created by the M3 team. The Sakura firmware has an integrated media player that plays music and video files in several formats, including DPG and DSM video, AAC, MP3, OGG and MOD. The player also displays text files and images in JPEG, BMP, GIF and PNG formats. Other features of the Sakura firmware include creating backups of each game and restoring them to a specific point in the game.

a word of warning

Be careful not to rename the extension on .is1 files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .is1. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
