Krypt has updated DC Factory with the following news:

MRTools v0.2 is up, and is now able to extract the sega logo from an ip.bin! Read the included mrtool.txt for details!
I’ve also received word that a DreamMSX self-boot script for DCFactory is currently being developed by a third party. Stay tuned.

MRTool v0.2 Information

Allows manipulation of the .MR format used to store images inside an ip.bin for display upon game startup. Converts .BMP <=> .MR, and allows you to both inject and extract .MRs from IP.Bins.
NOTE: There are no GPL violations here. Quoth the readme: The .mr compression scheme has been adapted from AndrewK’s C implementation. Decompression code was written by me. . My code is in Delphi (Pascal), AndrewK’s was in C. I didn’t take a single line from him, I simply studied his compresion code, and from it, wrote my own. Decompression code is fully mine. I repeat again, no GPL violations here, as I didn’t use any of his code. It’s not that I’ve got a problem releasing source, it’s the the source is UGLY, and I’m ashamed… If you’re a Delphi programmer who really wants the source, contact me.

ChangeLog:
v0.2
– Support for images with resolutions other then 320×90
– Error messages fixed (wrong msg when height > 90)
– New -scan option will extract sega logo from an ip.bin.
