Stephen Anthony a6fe6e0bd8 Oops, forgot to remove some documentation editing typos. 2017-07-09 22:43:09 -02:30
Stephen Anthony d613173cd7 The default phosphor blend level can now be set globally (fixes #144). 
Added new 'tv.phosphor' commandline argument to accomplish the above,
and associated UI item in Video Settings.

Updated docs for 'tv.phosphor' and 'tia.debugcolors'.  More work is
needed on this, since I need to add screenshots for this new functionality.

Stephen Anthony 6d4a98d735 Updated version for next pre-release. 2017-07-05 18:04:27 -02:30
Stephen Anthony 970804b9f3 Optimization: modify RGB pixel data locally instead of calling functions. 
This is allowed, since after analyzing the code, we see the pixel format
will always be ARGB8888 mode, so we can hard-code the logic to do the
conversion.

This leads to a measurable performance improvement, since we eliminate
3 function calls per RGB colour lookup.  And the calls themselves involved
IF statements and various other shifts that weren't needed.  Assuming
normal phosphor mode with 160x210 pixels, this saves 100,800 function calls
per frame!

Stephen Anthony 6da07d8dc7 Optimization: eliminate redundant access through a struct. 2017-07-05 13:06:44 -02:30
Stephen Anthony 09af9d09a5 Finally fixed issue #75 (phosphor mode now works with Blargg). 2017-07-05 12:48:39 -02:30
Stephen Anthony 1d293df782 Updated changes for system label lower vs. upper case. 2017-07-04 20:24:19 -02:30
Stephen Anthony d88969adcb Store and lookup system labels (aka, equates) in case-insensitive manner. 
This fixes a bug in the debugger parser, where typing (for example)
'trap swchb' doesn't work but 'trap SWCHB' does.

Stephen Anthony 7b57d52260 My neverending quest to protect against raw pointers. 
Changed many 'const char* ...' to 'const char* const ...'.
 2017-07-02 20:46:27 -02:30
Stephen Anthony 9972af022a Fairly huge refactoring of the cart autodetection code. 
This has been in patch form for about a year, and I'm finally
getting around to applying it.  Basically, we separate the Cart
class into 3 classes:
  - Cart: stuff specific to cartridge emulation
  - BSTypes: various bankswitch types, both as enum and strings
  - CartDetector: actual bankswitch auto-detection code

Also made more use of smart pointers, and added const in a few
more places.

I promise to get back to the phosphor stuff soon.  This is just
to clear my head a little.
 2017-07-02 19:27:27 -02:30
Stephen Anthony 2e776b05b8 Introduced 'tia.dbgcolors' commandline argument, which allows to set 
the fixed debug colors to user-defined preferences.  Note that there
are 6 registers (P0,M0,P1,M1,PF,BL), and the option takes a string
of 6 characters, where each represents a colour for the respective
positional register (ROYGBP are the choices).

I may add a UI item for this, but this is as far as I will go with
allowing user editing.

Stephen Anthony bd78683274 Rearranged some Blargg code, added comments, general cleanups. 
For now, Blargg phosphor mode simply shows the same image as without phosphor.
This is a WIP, and if we can't get it finished for 5.0, it will be released as-is.

Phosphor blend now defaults to 0 in the base properties, and is converted to
50 before being passed to higher levels.  This needs to change when we
get to issue #144.

Stephen Anthony 881dc86ab7 Oops, we need to handle the case where the controller is undefined. 2017-06-18 21:59:04 -02:30

Stephen Anthony 705d42edd8 Updated Visual Studio project file for Blargg code changes. 2017-06-17 20:40:11 -02:30
Stephen Anthony 0f2df7e87b Fairly large reorganization of the Blargg NTSC TV effects code: 
- converted many pointers to references
  - merged code from several files into one class
  - broke up some methods into more managable chunks

This will allow it to be easy to add the phosphor code during
NTSC TV emulation.
