The second intermediate version of MAME v.106 has been released on the public. If you like to use the intermediate updates, head over to Mamedev.org and get the new files. A word of caution though, the latest build starts an overhaul of MAME's video system, and as a result there may be many bugs and broken games. Per the MAME what's new file;
"IMPORTANT NOTE: The video system in this version has been completely upended and redesigned. The old video system is still the default; however, some features may be broken. These are not bug-worthy reports, as the old system will soon be deprecated. The new system can be compiled by setting the NEW_RENDER flag on in the makefile.
THE NEW SYSTEM IS STILL WORK-IN-PROGRESS! Apart from video card- related issues (like it doesn't work on particular hardware or has an incorrect display), bugs are not being tracked at this time. There is already a laundry list of things that are broken at the top of render.c, and there are many other things that still need to be looked at.
In order to run the new video system with hardware acceleration, your machine will require DirectX 8 or later." - MAME V.106U2 What's New file
At this point, we'd like to once again suggest that you take the MAME development team's advice and stick with V.106 proper unless you really want to test out the changes. Click here to see what's new in this update.
