Do try that desire_09 before and after, it's quite striking smile

eta: SCSP is basically feature-complete now except for FM, and that's mostly because I haven't seen any Saturn or STV games that use it. (Well, that and it's not the most understandable part of the docs).

The better news for the future is that the AICA is essentially a straight superset of the SCSP, so if someone started making DSF rips for real (a working open-source DC emulator would help) it wouldn't be the end of the world to get them going.
