I think that the problems we currently encounter is caused by random use of lower/upper case letters for the rom names. Moreover the casing was different between the docs and actual code, so matching readme will not help. And I think, once it would be clear that all files and dirs need to use lower ...

Secondly, proposed patch only ignores case sensitivity for the files, not whole dirs (and we have dirs inside roms directory). Using consistent naming also address that situation and it's a lot simpler.
