Set emulation back to NTSC (i haven't really implemented PAL properly yet anyway). Set disk gap to 348 to match some documentation i have on disk gap sizes, it may still be wrong.

Finally fixed the problem with line drawing Suspect that in line mode the texture is simply repeated into the old channel. This would also work for the A channel, but i`ll need to confirm what the real hardware does.

Correction to copper emulation, it should halt on attempt to write to disallowed custom registers.

Added dma check and window vertical position checks for display hardware. Its a temporary measure as i need to re-write this again to match the hardware cycles properly.

While working on syndicate i needed to increase the amount of ram available to the amiga. I chose the simple route (which is to increase chip memory size), unfortunately this caused problems. As the game code sees the extra chip memory and assumes the custom chips can access it to. So i've fixed up all the hardcoded custom chip ram masks. This allows syndicate to get a bit further.

Improved debugger functionality. Can now show copper dissasembly + track program counter history. Added ability to invoke debugger from code and used it to trap things that have not been emulated properly yet.

First pass at audio. Disabled the output though because the noise i get is not pretty.

Cleaned up some warnings. Fixed up a few mistakes in the dissasembly. Added lazy register display for movem instructions e.g. MOVEM.L d0/d1/d2,(a7) will fixup to the more accurate : MOVEM.L d0-d2,(a7) at a later date.

Phase 1 complete. Dissasembly refactored. Cpu emulation now has capability to be staged (ie, instructions take more than 1 cycle - which they should).
