Dreamcast Emulation is far from perfect, a real console is still the best option but the game is not exclusive to Dreamcast so you could always go for the PSX version as the PSX has much better emulation of the machine vs Dreamcast
You can try other Dreamcast emulators though like demul that is the best one or latetest builds of nullDC (the official site only has the older build, that you may have unless you got the latest build from our forum, I don't know as you never stated the version)
I obviously use a real console
