Hacking MVS v2.3.1 Conversion Tools? -- What Are They For

[Another World]

I grabbed an Unofficial build of MVS 2.3.1 that supports the Universe Bios. In the package are a bunch of tools and I am unsure what they are used for. Can someone explain their use for me? I read a bit about converting but I do not know to what end. Do ROMs need to be converted from their .ZIP format into something else?

mvsconv.bat
mvsconv_all.bat
mvsconv_slim.bat
mvsconv_slim_all.bat
romcnv_mvs.exe
rominfo.mvs

Thanks!
