Convert DTM to VM1

Understanding DTM and VM1 file formats

DTM files are typically associated with DeSmuME, a popular Nintendo DS emulator. These files store movie recordings of gameplay, capturing input data rather than video, allowing for precise playback and sharing of gameplay sessions.

VM1 files, on the other hand, are used by VisualBoyAdvance-M (VBA-M), a Game Boy Advance emulator. The VM1 format is also a movie recording file, but it is specific to VBA-M and is not directly compatible with DTM files.

Why convert DTM to VM1?

Converting a DTM file to VM1 is useful if you want to replay or share your Nintendo DS gameplay recordings on the VisualBoyAdvance-M emulator, or if you need to standardize your movie files across different emulators.

How to convert DTM to VM1

There is no direct converter that automatically transforms DTM files to VM1 format, as these files are tied to different emulators and systems. However, you can use the following workaround:

1. Open your DTM file in DeSmuME and play back the movie recording.
2. While the movie is playing, use a screen recording tool (such as OBS Studio or Bandicam) to capture the gameplay as a video file (e.g., MP4).
3. Open VisualBoyAdvance-M and load the corresponding Game Boy Advance game.
4. Use the video as a reference to manually record a new VM1 movie file in VBA-M by replicating the inputs.

This process is manual and may not be perfect, but it is currently the only way to transfer gameplay between these two formats.

Recommended software for the process

• DeSmuME – for playing and recording DTM files (File → Movie → Play Movie).
• VisualBoyAdvance-M – for recording VM1 files (File → Start Movie Recording).
• OBS Studio – for screen recording during playback.

Summary

Direct conversion from DTM to VM1 is not supported due to emulator and system differences. The best approach is to replay and manually record the gameplay using the recommended emulators and screen recording software.
