FrodoDS problems

Please forgive my stupidity. I am new to emulators and have decided to jump right into using Frodo on my DS Lite. Perhaps a bit of a stretch for me but I'd like to try. The C64 brings back quite fond memories for me. Anyway....

I pulled down the .nds file, placed a couple C64 roms in /rd directory.

When I start up FrodoDS it starts fine but then kicks out a error saying that it can't read the ROM disk /rd/

I did some searching around and it seems I have to create a ROM disk using a batch file that everyone seems to think you should have.

It is called createromdisk.bat I believe but for the life of me I don' t know where to get it or what other files are required for this ROM disk creation.

I did pull down this file:genromfs-cygwin.zip. Instructions were as such:
"rename it to genromfs.exe or update the included createromdisk.bat file."

But I don't seem to have the .bat file that is supposed to be included somewhere.

If anyone would kind enough to point out what I am missing it would be greatly appreciated.

Thanks
