==CPUs/Timing==
==CPUs==
* universal DRC backend
* write x86 DRC front-end, unifying all x86/NEC variants
** define common IR that all DRCs compile to
** write backends for x86/x64
** also write canonical "C" interpreted backend, designed to be run in parallel
** update MIPS3 DRC to the new backend
** look into TMS32031 and/or ADSP support
* investigate and fix TMS32031 calculation bug
* investigate and fix TMS32031 calculation bug
* replace cpuexec.c and timer.c with more generic scheduler
* add MDRV_SCANLINE interrupt generators
* change MDRV_CPU_VBLANK_INT to specify a screen number
* change MDRV_INTERLEAVE to specify interleave as per-second, not per-frame
* add timed interrupt generator: cpunum_toggle_input_line_timed(cpu, input, time). This will ASSERT_LINE immediately and then CLEAR_LINE after the specified time. 'time' can be zero, which is equivalent to PULSE_LINE, though perhaps we should discourage such usage since it's not realistic. If you've asserted the line via this function, and another cpunum_assert_input_line_timed() call is made, it will override the previous CLEAR_LINE time with the new time. Note that this is not a proper wire-OR, so we could alternatively reschedule the CLEAR_LINE to the maximum of the new time and the previously pending time.


==Debugger==
==Debugger==
* add timer window
* add CHD viewer window
* make workable in a fully command-line fashion
* convert to using pipes

void scheduler_abort_execution(void);
* Clients can be suspended/resumed:
void scheduler_client_suspend(scheduler_client *client, UINT32 reason_mask);
void scheduler_client_resume(scheduler_client *client, UINT32 reason_mask);

mame_time scheduler_get_global_time(void);
mame_time scheduler_client_get_current_time(scheduler_client *client);
mame_time scheduler_event_get_fire_time(scheduler_event *event);
* Scheduler keeps track of real time spent executing (debug only?)

    • Accepts array of 8 32-bit parameters
    • Hashes those parameters and performs lookups
    • Automatically manages via LRU
  • Pre-compute textures in voodoo at upload time and remove on-the-fly format conversion for a bit more speed

Video

  • render crosshairs in UI layer not in game containers
  • game-specific crosshair bitmaps and sizes
    • user selectable?
  • fix crosshair rendering to understand scale and offset factors
  • font improvements:
    • start with built-in font, then load others
    • standardize on BDC as the font format, provide BDF2BDC converter
    • find a good unicode font
    • user-selectable at runtime via menu?

Outputs

  • convert output system to use pipes
  • add ability to get XML description of current game

Drivers

  • write tests to figure out 3dfx mipmapping algorithm
  • remove use of MDRV_VBLANK_INT(count) where count > 1
  • cliffhgr.c:
    • add proper latching/buffering to ensure no dropouts
    • fix 9928a emulation to match screenshot (broken link)
  • 3DO-based systems

Documentation

  • write debugger documentation
    • Debugger basics (covers the main window, the keyboard shortcuts, and a couple of very basic commands)
    • Viewing memory (covers disasm/dump, memory and disassembly windows)
    • Breakpoints and watchpoints (covers basic breakpoints and watchpoint usage)
    • Expressions (covers using expressions to change values and the whole expression syntax)
    • Advanced breakpoints and watchpoints (covers conditionals, actions, etc)
    • Other techniques (covers tracing and other things)
  • write description for how to compute crosshair parameters

Other Stuff

  • look into inpout32.dll for hooking up ZVG to WinMAME
