List of changes to MAME core

PA_SOUND

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

[Robert]

GIGATRON

src/devices/cpu/gigatron/gigatron.cpp

line 94: commented out because MESSUI would crash when this system was started. Still needed?

 

[Robert]

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.

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.

 

[Robert]

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.

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.

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.

[Robert]

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.

[Robert]

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.
