It should be like any other Sound Blaster Pro 2 (no bugs in particular). The only notable difference is the Mitsumi CD-ROM interface and controller chip (which means that the PCB is also longer).
Some people say that this is actually 'the best' SB Pro 2 and that it has the cleanest sound (being one of the later models).
I don't have this one, I only have the CT1600, so take what I just said with a grain of salt. 😀
Anyway, regardless of all that, it's a SB Pro 2, so it's one of the most compatible cards you can get for a 386 / 486 machine.
On the other hand, it's not so useful for later machines from the Pentium MMX / Pentium 2 era, since the SB Pro 2 is actually more speed sensitive than something like an ESS ES1688 or ES1868 (unless you slow down the CPU, something that you can easily do with a Pentium MMX, not so easily with a Pentium 2).
