Mame.127 has been released.

Most noticable is the laserdisc support. Don't know if this is working at the moment.

Thanks for the information  Kiss

Here's a part of the what's new :

Added new generic laserdisc VIDEO_UPDATE handler to the laserdisc code.
This handler works for both disc-only games and those with overlays.
For disc-only games, the base macro is sufficient. For games with
overlays, an additional set of configuration macros are provided:

   MDRV_LASERDISC_OVERLAY - specifies update function, width, height,
      and bitmap format of the overlay
   MDRV_LASERDISC_OVERLAY_CLIP - specifies the visible area of the
      overlay bitmap
   MDRV_LASERDISC_OVERLAY_POSITION - specifies default x,y position
   MDRV_LASERDISC_OVERLAY_SCALE - specifies default x,y scale factors

The update function provided to MDRV_LASERDISC_OVERLAY is identical to
a normal VIDEO_UPDATE callback, so a standard one can be used. All
existing laserdisc drivers have been updated to support this new
rendering mechanism, removing much duplicated code. [Aaron Giles]

Added the ability to configure the overlay position and scale
parameters at runtime. Added OSD menus to control them. Added logic
to save/restore the data in the game's configuration file.
[Aaron Giles]

Added new macros MDRV_LASERDISC_SCREEN_ADD_NTSC and _PAL, which
defines a standard screen with the correct video timing characteristics
and update function for laserdiscs. Updated all drivers to use these
macros instead of defining their own screens. [Aaron Giles]

Added DISK_REGIONS to all laserdisc drivers. [Aaron Giles]

Added DISK_IMAGE_READONLY_OPTIONAL to support games (like Cube Quest)
where the disk is non-essential to the game's operation. [Aaron Giles]

Fixed bug in identifying the custom sound driver for the laserdisc.
[Aaron Giles]

Updated ldverify to identify blank regions of the disc for post-
processing. [Aaron Giles]

Fixed rendering 16bpp with alpha using bilinear filters (fixes
screenshots of laserdisc games with overlays). [Aaron Giles]

Included support for parsing .gdi files in chdman. [ElSemi]

Added new driver for Cube Quest. This includes CPU cores for the three
bitslice processors, as well as laserdisc support for the hacked
laserdisc that was used to drive the games.
[Philip Bennett, Joe Magiera, Warren Ondras]


New games added or promoted from NOT_WORKING status

Heh...I used to know a few people behind the scenes on the mame project, a long time ago...I had suggested that they try to do the laser games and was put in my place. Amazing how things can change in 10+ years....It is long over due.
