hrydgard 957127d505 DSP: minor shift instruction tweaks. that stuff about negated shift amount in the comments is spooky though. gonna have to run some test code.

hrydgard 0fd2edbf98 DSP: Remove all mentions of the mysterious DROM. Write protect the ROMs and IRAM as much as possible while loaded (to make sure they don't get corrupted by some memory overwrite or whatever). Make instruction reads stricter - iram and irom don't wrap anymore (not 100% sure about this one). Misc cleanup + changes.

hrydgard 4913912dbb DSP: Restore CMPI and its disasm. Attempt a correct implementation but results seem worse, dunno :p (playing around with Hermes' DSP demos). Fix error logging to log pc-1 instead of pc since pc has already been incremented. minor cleanups.

hrydgard 6eb6db21ce DSP - fix ROM loading (seriously, have we only been loading half the ROMs??? doesn't make sense). 
Also delete some unused old junk variables. Add some comments. Start #defining SR flag constants. "implement" nx.

nakeee 472e67333f more opcode work removed CW as it makes problems, we can check for unknown instead. 
to check:
- TST implementation seems diffrerent from docs
- CMPAR seems to cause errors in AX games (why? dis we skip clear???) - commented out for now

We are still missing tons of opcodes which I'm not sure where to put...
