Out of whatsnew: there are still a few files being worked on, and the build scripts which are currently set up outside of the MAME source hierarchy. Always open to cleaner ways of doing things.
out of whatsnew
remark 1- this is for MESS only to my knowledge, let me know if I should credit the change in MESS instead
remark 2 (mainly for Arbee) - sorry if I touched the SDL side of the source, but mizapf was eager to fix the ti99 issues
and since tlinder approved the change and you did not object on the MESS list, I think it was time to commit it ;)
loader rewrite, which is still in progress....)
Replaced mamedriv.c with a new driver list mechanism that is generated
by the build tools. The emulator core now expects the presence of a
file called src/$(TARGET)/$(SUBTARGET).lst which is just a raw list of
driver names, one per line. C and C++ comments are still permitted.
This file is parsed by a new build tool makelist which extracts the
driver names, sorts them, and generates a file called drivlist.c, which
is consumed by the core. [Aaron Giles]
Added new osdcore function osd_malloc_array() which is identical to
osd_malloc() but obviously hints that the underlying allocation is for
an array. Updated all callers to use the appropriate form. Modified the
Windows allocator to only use guard pages for array-style allocations,
allowing us to enable them once again in debug builds. [Aaron Giles]
Created new static class driver_list to wrap accesses to the list of
available drivers. Improved speed of driver lookups by relying on the
presorting done by makelist. [Aaron Giles]
Created helper class driver_enumerator as a helper for iterating through
the list of drivers. This class supports basic filtering and iteration,
and also serves as a temporary cache of machine_configs. [Aaron Giles]
Created cli_frontend object to wrap all the CLI handling code in
clifront.c. Updated/simplified all the code to take advantage of the
driver_enumerator. [Aaron Giles]
Created media_auditor object to wrap all the auditing functions in
audit.c. Updated all users to the new interface. Note that the new
auditing mechanism is slightly out of sync with the romload code in
terms of finding ROMs owned by devices, so it may mis-report some
issues until the new ROM loading code is in. [Aaron Giles]
Added concept of a per-device searchpath. For most devices, their
searchpath is just the short name of the device. For driver_devices, the
searchpath is driver[;parent[;bios]]. This searchpath will eventually be
used by the rom loader to find ROMs. For now it is used by the media
auditor only. [Aaron Giles]
Created info_xml_creator object to wrap all the info generation functions
in info.c. Converted the file to C++ and cleaned up the input processing
code. [Aaron Giles]
(not for whatsnew ... Known issues: auditing of CHDs appears busted, and
debug builds report unfreed memory if you use the built-in game picker)
- Moved "known bugs" to README_SDL13.txt
This is what has been there:
- fixed returning (w,h) = (0,0) in get_max_bounds
- new video driver "sdl13" utilitizing SDL texture and line
drawing support. Accelerated drivers like directfb now
may attain opengl speed. DirectFB does with a radeon card.
The driver determines which pixel formats perform best and
converts textures to these pixel formats.
Supported options:
-waitvsync
-filter
-prescale
Supported renderdrivers:
X11: opengl, software, x11 (no artwork!)
DirectFB: directfb, software, opengl (special setup, slow)
Windows: software, gdi (no artwork)
- SDL1.3: Clear bck when moving
- SDL1.3: now compiles on win32
- SDL1.3: Support screen refresh rates, provided the sdl video
layer supports them (e.g. X11).
- Use video_config.waitvsync (previously option was queried)
- -video soft / -sm now supports -prescale
- removed reqwidth, reqheight from sdl_monitor_info; not used anywhere
- removed layerconfig from sdl_video_config; not used anywhere
- fixed yuv issues (firefox) / this was a bug I introduced
- removed deprecat.h from output.c
- Separated keyboard and mouse initialization into separate functions
- added _FORTIFY_SOURCE to verbose compiler define output.
- remove MAX_CPU from debugwin.c
- fixed vsync handling in SDL1.3 in soft/opengl drivers
- "waitvsync" also supported by "soft" driver in SDL1.3
- multiple mice and keyboards supported in SDL1.3
- support for DISTRO= make option
- got rid of "-joymap" and "-joymap_file"
- add -joy_idx[0-7] -keyb_idx[0-7] -mouse_idx[0-7] which
specify, which device is allocated to to e.g. Mouse 1, Mouse 2, ...
- moved define of THREAD_COOPERATIVE into sdl.mak and renamed to
NO_THREAD_COOPERATIVE. Changed references to #ifndef
- define NO_DEBUGGER in sdl.mak
- Solaris now uses -DNO_AFFINITY_NP
- added machine to window_info, removed deprecat.h from drawogl.c
- For DEBUG=1 builds, disable input grapping while windowed
- Fixed WIN32 compile
Wrote setenv function since mingw does not provide one.
Implemented osd_event_* as inline functions for win32 build.
We should at some point merge sdlwork.c and winwork.c and push it
to the core, letting sdlsync.c provide the necessary details.
- Removed keybled.c and references
- Added output.c and output.h. These will look for a fifo or file
/tmp/sdlmame_out and write output notifiers to it.
Added a sample client ledutil.sh to src/osd/sdl which turns
leds on and off and provides a debug (log) facility.
- removed os2work.c
- replaced window->render_lock with event window->rendered_event
For multiple windows and "-mt", the old code would allow filling up
the workqueue with 1000s of entries, since the lock would not block while
another window is rendered. The osd_event establishes a barrier which
is only freed if the last window blit operation has finished.
- Set SDL_VIDEO_GL_DRIVER if -gl_lib is given. The SDL directfb driver is picky about
this. Added reminder: FIXME: move lib loading code from drawogl.c here. This may be
used to disable opengl if no library was loaded.
- SDL1.3/video=opengl: Fixed windows not being updated after another window was resized
- for -verbose, output some information about renderer (-video soft)
- initialize mouse_enabled with option "-mouse". Affects both SDL1.2 and SDL1.3
This will hide the mouse if you specify "-mouse".
- SDL1.2: added blitmode "async" which sets SDL_ASYNCBLIT
- SDL1.2: removed blitmodes "hwbest" and "hwblit"
- added blitmode "hwbest" for antialiased and smoothed scaling now that the
directfb driver supports it. This is also supported by the 1.3 opengl
render backend
- added sdlinput_release_keys to cope with lost keyboard events in SDL1.3
- some identing in drawogl.c
- rename SDL_* macros to SDLMAME_* (avoid name clashes)
- got rid of VIDEO_SCALE_MODE constants. Scale modes are now handled in drawsdl.c.
Starting mame with eg. -video soft -sm yuy2 on X11 no longer crashes.
- some more changes to input.c to avoid resize loops (issue for directfb)
- working ui mouse inputs for SDL1.2 and SDL1.3 incl. yuv modes
- added blitmode "hwblit" (SDL1.3) for rgb hardware scaling
- rename "-yuvmode" option to "-scalemode"
- rename yuv_mode and derivatives to scale_mode
- moved extra_flags into sdl_info
- moved callbacks indow sdl_window_info
- made a number of flags (e.g. yuvmode) window relative
- changing of yuvmodes and opengl scale effects is working with SDL 1.3
- improved fullscreen handling
- removed HAS_WINDOW_MENU - this has no effect nowhere
- removed underscores in header defines, e.g. __SDL_SYNC__ ==> __SDLSYNC__
- added SDLMAME_HAS_DEBUGGER define
- removed #if 0 inw window.c
- added option "-audiodriver" to specify the SDL audio driver
- added option "-videodriver" to specify the SDL video driver
- added option "-renderdriver" to specify the SDL renderer driver
- changed environment SDLMAME_GL_LIB into option -gl_lib
- added some more SDL_ENV defines
- move keymap reading into separate function
- SDL_EnableUNICODE for all builds (not only MESS)
- SDL1.3 : Mouse & text input for ui
- removed osd_event_wait_multiple from sdlsync.h
- removed some includes not needed
- reorganized texcopy/scale2x
- removed effect.h
- removed effect_func.h
- indenting
- put osd_copyfile, osd_stat into #ifdef MESS
- added code which implements events without the need
for pthreads. This is commented out, since
owever, it horribly fails, if
threads > num processors as is the case if you
enable "-mt"
- rename mame_bitmap to bitmap_t
- introduced define OSDWORK_CALLBACK to prototype and
define functions to be passed to sdlwork.c
- fixes from judge for warnings / may reappear (glade)
- more warnings fixed / may reappear (glade)
- moved osdefs.h into sdlprefix.h
- removed osdefs.h
- finally removed sdlmisc.h
- create drawogl.c and moved ogl relevant stuff there
- draw.window_init() now called after window creation
- removed window.opengl flag
- added sdl_window_info as parameter to all functions in window.h
- rename SDL_VERSIONNUM to SDL_VERSION_ATLEAST
- removed all uclock stuff in sdlmisc.[ch]
- minor cleanups
- fixed compile issues against SDL13
- fixed input issues with SDL13
- stricter checks for USE_OPENGL, e.g. for options
- move sdlvideo_loadgl to window.c, rename it to sdlwindow_loadgl and make it static
- moved yuv_blit.c into drawsdl.c

- fixed some compile issues
- moved clear_surface into window thread
- got SDL1.3 -mt working - still crashing on exit
- removed "digital" option
- removed device selection options
- added more SDLOPTION defines
- Added sdlmisc_<targetos>.c again. This was necessary since
certain tools create stubs for e.g. osd_break_into_debugger.
If we do not have this in a separate file, the link stage may
break.
- Applied OS/2 patch [Credit: KO Myung-Hun]
- Cleaned up #includes. Removed stdlib.h were possible.
- More malloc to osd_malloc rename.
- SDL monitor modes are read now when they are needed. This is now consistent across platforms.
