Best current way to play Code Veronica?

I had CV for the Dreamcast and despite the fact that I didn't finish the game it's one of my favorites in the series. I'm ready to give it another shot and I see that CVX is available to stream or buy on PS5 and available for purchase on the Xbox store.

- Is there a way to play the original Code Veronica or would I need either a DC or a PC for that?

- Should I just stream the PS5 version of CVX since it's free or is there a gameplay or quality reason to buy

the game outright on either system?

- I tried the PS5 streaming version for a few minutes and didn't like the default controls because run/action

were reversed from RE1-3. Can I change the control scheme on any version?

Thank you
