This python project is designed to be a fully loaded suite of VMU tools for the Dreamcast.

• Read and extract data from .VMS and .VMI files
• Generate icons from ICONDATA and VMS files
• Generate VMI files from VMS
• Read and manipulate VMU dumps files
• Extract and upload save games from VMU dump files
• update VMS icons from PNG and JPEG

Checkout examples.py and example files for all features

pip install vmu-tools --upgrade

import vmut

# Load .VMS file
VMS = vmut.vms.load_vms("example_files/SCALIBUR.VMS")

# Print info
print(VMS.info)

# Save icon
VMS.image_save("animaed.gif")

# Generate Checksum
print(VMS.generated_crc())

#Generate VMI
VMS.vmi_gen("test.vmi", "slurmking.com", "test VMI file")

#Fix crc
VMS.fix_crc()

For best results use a square image scaled to 32x32

vmut.Icon(image="example_files/slurm.png", threshold=160, invert=True).save()
