JR100 Today I added a new hack into MESS/MESSUI only. This fixes a VIA bug by changing its clock frequency on the fly. The result is that the jr100 can save and load cassettes correctly. It's too much of a hack to be considered for MAME.

DEFAULT INPUTS src/emu/inpttype.cpp lines 877, 878: change Pause button to the Pause key on the keyboard. The old P key is needed for other things. line 915: In MAME, the default Paste key doesn't work. Moved to RightShift+PgUp.

EXTRA SLIDERS src/frontend/mame/ui/ui/cpp line 1490,1519: extra sliders such as overclocking are normally only available if cheating is enabled. We make these sliders always available.

DIRECT3D src/osd/modules/render/draw3d.cpp lines 1063-1113: various tests for old video cards have been commented out. In MAME you would get a fatal error or black screen. In MAMEUI the worst you'll get is a black screen, but more likely it will work. So, messages such as "Your graphics card does not fully support non-power-of-two" won't be seen.

There's most likely more changes that were done as a test and then forgotten about, or simply never documented. Hopefully these will be sorted out soon.

NONAG src/emu/video.cpp line 967: changed "> 0" to "> 1". Then you must choose -str 1 from the command line (or seconds to run = 1 in the GUI). This is for MESS/MESSUI/ARCADE64 only, in order to comply with licensing restrictions.

INP_HEADER This is needed by all derivatives to allow the loading of INP files. However a pointless refactor 2 months ago made this class private, and not available. src/emu/ioport.cpp src/emu/ioport.h Moved the inp_header class from ioport.cpp back to ioport.h where it belongs.

GIGATRON src/devices/cpu/gigatron/gigatron.cpp line 94: commented out because MESSUI would crash when this system was started. Still needed?

PA_SOUND 2022-04-27 hack not needed, changed back to standard

ABOUT src/frontend/mame/ui/about.cpp line 51: In the About header, MAME shows a revision number, however this only works if the exe was compiled on an internet-enabled computer. For me, it always says "unknown" which is useless. Therefore it's changed to show the creation date instead.

SLOTS src/emu/mconfig.cpp line 102: there's a fatal error if an unknown slot option is encountered. This has been changed to a warning because the system will handle the problem gracefully anyway. MAME has more than enough ways to crash as it is.

WARNING OF NO SOUND src/frontend/mame/ui/info.cpp line 211: line has been commented out. Not sure exactly what it's about. The note says "The no sound hardware warning doesn't make sense when you plug in a sound card". Need to find out more.

SOFTWARE LISTS src/emu/softlist_dev.cpp Many pointless changes were reverted to keep winui working, mostly to do with the dangerous string_view statement. line 94, 294-305: this area was refactored and it broke things, reverted to a working state. src/emu/softlist_dev.h line 152: added back needed definition of m_file. src/emu/softlist.cpp line 122, 140, 146, 564: get rid of string_view so things can work again. src/emu/softlist.h line 124, 142: adjust pointers to fit with the above.

VIDEO SPEED from NewUI. src/emu/video.h line 58: addition of pointer to the speed adjuster. This had been removed in a pointless refactor a few years back, but we need it.

AUDITING OF ROMS src/frontend/mame/audit.cpp line 710-783: only report on roms that the user can fix. There's no point complaining of no dumps and bad dumps, when there's nothing the user can do about it. src/emu/romload.h line 415: returns number of no-dumps and bad-dumps. We don't need this, so return 0. src/frontend/mame/audit.cpp line 707 to the end: new audit routine to support the above ideas. src/frontend/mame/audit.h line 162: pointer to the above.

DEFAULT LANGUAGE 2022-04-27 removed this hack, it's back to standard.

CATEGORIES IN MAME MENU 2022-04-20: this issue has been resolved

MANDATORY IMAGES, NewUI MOUSE src/frontend/mame/ui/ui.cpp line 562: if the system requires software before it will start (nes for example), you get the filemanager. This line has been commented out, allowing you to start the system without software, and you can load it later if you want. line 677: fix when the mouse pointer should show. If NewUI is on, then the mouse pointer is always there.

BIOS ERROR (Updated 2022-04-24) src/emu/romload.cpp lines 370, 375, 392: stops the menu from complaining about invalid bios src\frontend\mame\ui\selmenu.cpp lines 634-638: gets rid of the bogus 'files are missing' after running a neogeo game.

DEFAULT OPTIONS src/osd/windows/winmain.cpp line 174: MESS/MESSUI only - enable NewUI by default. (The white menubar that shows when a game is running). line 292-335: new main function for winui, it become necessary several years ago after a pointless refactor. src/osd/windows/winmain.h line 273: link to new main function src/osd/module/lib/osdobj_common.cpp line 59: default to window instead of full-screen line 97: turn bilinear filter off by default. src/emu/emuopts.cpp line 35: MESS/MESSUI/MAMEUI - the writeconfig option is turned on default. This means whenever you run a game, a new inifile will be created. You can turn it off in mame.ini . Having it on is handy for MESS (imagine having to completely rebuild a pc every time you wanted to use it), but not useful for arcade. You can make arcade.ini with one line: writeconfig 0 line 701: if option not found (can occur with BML3 with 1802 slot), MAME will blow up. This is changed to handle it gracefully. src/lib/util/options.cpp line 284: crash if attempt to set an invalid option. This has been commented out, need to find out if needed.

DEBUGGER src/emu/debug/dvmemory.cpp line 340,397: in the ascii part of the memory view, bit 7 will be stripped, so you can read text that has bit 7 on, instead of getting greek or whatever.

PLUGINS src/frontend/mame/mame.cpp line 174,184,195: If there's a problem with a plugin, MAME will crash. This has been changed so you get a console message and things continue without it instead. src/frontend/mame/pluginopts.cpp line 77,83: don't crash if bad plugin.

LUA STARTUP src/frontend/mame/luaengine.cpp line 462, 540, 922, 927, 933: If LUA is unable to initialise itself, MAME will crash. This has been changed so that LUA will be disabled and the emulator will run without it.
