Should I open a new thread?

Probably yes, it will make searching easier for any other users to find answers if they may have the same or similar issues in the future.

In theory should be possible with bluemsx (not sure how well implemented the libretro version is) but from what I was reading running .cas looked a bit involved, there was a bit of a guide I saw on the bluemsx forms but I don't think I can link to it as it looked like it had ROM or bios links.
