Switched the SMS and Game gear PSGs to use an XOR instead of XNOR feedback, but this needs further verification. Updated comments to show which chips are currently verified. Cleaned up comments.
- now properly generating TLB fill exceptions under correct circumstances
- TLB exceptions no longer trash low 4 bits of Context
- exceptions with the EXL bit set always go to vector 0x180
future lookup optimizations.
By and large, the only things that used 2-character tags were bulk-
converted sound chips which were generally mapped to "ym" or "ay"
(and a few others). These were changed to "ymsnd" and "aysnd",
mimicking the way CPUs were changed from "main" to "maincpu" a while
back.
- Reworked PMMU/core interface so PMMU now sees all cop 0 instructions
- Improved disassembly of PMMU instructions
- Preliminary 68LC040 support
- Fixed disassembly for EC/LC variants of '030/'040

Originally the key extractor generated a false positive, but David had it continue after the first key and the second one generated works correctly

At some point the driver was updated and the CPU region for all other games is set to ROMREGION_ERASE00 while Final Gorodi & Wyvern Wings were marked as "0" ... changing this to ROMREGION_ERASE00 gets them running again.

Thinking about it, let's just use the code to generate irqs that he
sent, this lets the sprites go nuts, but I've noticed that since I
hooked up the line ram buffer it actually draws the sky in lineram,
thus confirming that it really is lineram.

Note the pcb had a lot of wire mods on it (being an early one), and the colors might not be correct yet, I'm getting some action shots from Andy to verify them. Also updated rom names for cosmica (version II) set since Andy has two of those pcbs, but I need a few more chip markings checked.
