well, games with DSP addon chip require the DSP dump, so the file you're trying to load is defective because it does not contain this necessary data.

until now we cheated treating the DSP as an additional SNES CPU (i.e. we added the fake snesdsp driver), but this is not accurate

so, in conclusion, DSP games will require to be loaded through softlists, because it is not possible to do otherwise, now that the DPS CPU is really emulated.
except for higan (which requires you to attach the CPU dump to the sfc file, specifying an xml layout), other emus still support these defective dumps by simulating the CPU instead of emulating it, but it's an hack and we removed it two yeas ago as soon as the DSP CPU was decapped
