A standard memory handler has as a prototype (where uX = u8, u16, u32 or u64):
uX device::read(address_space &space, offs_t offset, uX mem_mask);
void device::write(address_space &space, offs_t offset, uX data, uX mem_mask);
We now allow simplified versions which are:
uX device::read(offs_t offset, uX mem_mask);
void device::write(offs_t offset, uX data, uX mem_mask);
uX device::read(offs_t offset);
void device::write(offs_t offset, uX data);
uX device::read();
void device::write(uX data);
Use them at will. Also consider
(DECLARE_)(READ|WRITE)(8|16|32|64)_MEMBER on the way out, use the
explicit prototypes.
Same for lambdas in the memory map, the parameters are now optional
following the same combinations.
* Allow <orientation> and <color> to work on group references
* Fix some corner cases where group bounds could be miscalculated
* Fix a corner case where MAME could incorrectly refuse to instantiate groups
* Add more checks to complay.py
* Document more of the layout format
- Use line callback instead of VBLANK_INT and acknowledge interrupt
- Use (likely) addressable latches instead of pointers to (fake?) RAM
- Add watchdog timer
- Clean up audio CPU ROM region length

In commit ec325ef14f I did something stupid from
a performance standpoint, which was to select the shading function on a
per-pixel basis even though it can only change on a per-polygon basis. This
commit uses c++ templates and inline functions to so that the compiler's
constant folding can eliminate the switch statement that selects shading
functions (thus making the choice a per-polygon one). I also did the same thing
for the texture and bilinear filtering checks.
This brings back a little less than half of the performance hit on my PC, so
things still aren't as fast as they used to be.
Benchmark (running a full cycle of Crazy Taxi NAOMI's attract) on my PC:
Before ec325ef14f: 30%
After ec325ef14f: 23%
With this commit: 26%
Regarding the other 4% of the drop, that is coming from the pixel shading.
When I hardcode powervr2 to always use shading instruction 0, performance
jumps up to 29.5%, but when I hardcode it to use shading instruction 3
performance falls a bit down to 25%. Shading instruction 3 is the most
complicated of the four and shading instruction 0 is the simplest, so I think
that proves that the shading instructions themselves are a major bottleneck.
I don't have any ideas about how to make them faster yet.

there was also a disk for Paris Dakar, but the first tracks are damaged beyond repair, and it doesn't work, so haven't added it.
