Subject: Speed up 'src\mame\video\mcatadv.c'
Hi,
here is a patch against 'src\mame\video\mcatadv.c'
This patch moves a call to 'memory_region' outside of a hot loop in the 'draw_sprites' function.
This gives a fiew pourcents speed up in games such as 'nost'.
Hope this helps,
Best regards,
Christophe Jaillet

Subject: Another speed up in 'src\mame\video\mcatadv.c'
Hi,
here is a patch against 'src\mame\video\mcatadv.c'
This patch , by re-arranging the code, give a +/- 5% speed up in the emulation.
Before, we :
- fetch a pixel,
- make some computation for lower/higher part of it
- check if we should render it
- test for priority
- update destination if necessary
With this patch, we check priority first in order to avoid useless processing and testing on pixel that can't be displayed due to priority reason. So in the best case, it is faster, in the worse case execution time should be more or less the same because :
if ((drawxpos >= cliprect->min_x) && (drawxpos <= cliprect->max_x) &&
pix)
is likely to be true (IMO). So the same tests are performed, only the order is different.
Hope this helps,
Best regards,
Christophe Jaillet

Subject: Clean up of 'src\emu\tilemap.c' (with the patch...)
Hi,
here is a patch against 'src\emu\tilemap.c'
This patch removes a variable called 'original_cliprect' from the top of 'tilemap_get_tile_flags'.
This variable is useless because all cases that need it, already make the same copy in a variable with the same name, shodawing the former one.
Hope this helps,
Best regards,
Christophe Jaillet

In default mode the text gfxs overwrites the title screen when you put bets, is it correct?
(Notice that you should modify the bet button to try it because it's mapped at 2 as the start 2p button, it's a known MAMEtesters bug).
to names that capture the device type as well. Added validity
checks for the short-term to prevent the continuance of this
pattern (which I started :)
Changes:
CPU/"main" -> "maincpu"
CPU/"audio" -> "audiocpu"
CPU/"sound" -> "soundcpu"
SCREEN/main -> "screen" (since it's the only one)
Eventually, devices will be required to have unique tags within
a machine, regardless of type.

this is a heavily modified bootleg of Robocop. Phil hooked up some sound stuff, and I've got the graphics decoding sorted out.
the tilemap transparency handling is different to the original, as are the sprites, this will need a significant amount of work
one of the sprite roms is bad, but it looks like it should be possible to reconstruct it correctly from the main set.

Subject: [patch] Fix 02927: Many Sets using segaic16.c: Crash/Freeze while starting
Hi mamedev,
My multisession fix for fd1094 inadvertently dropped a call to memory_configure_bank that I wrongly thought was unnecessary.
Reverting that part of the change seems to fix this bug.
