Version 0.195 is scheduled for February 28th, although hot weather may cause a delay.
This will be 64-bit only. There won't be any more 32-bit builds.
The reason is that there are now so many Neogeo hacks that a 32-bit compile runs out of memory while trying to process them all. At the moment the Neogeo driver is split in half, but soon it would have to be split again as it grows. This is cumbersome and messy at the very least, so 32-bit will have to end. 64-bit does not have this problem.
The new 64-bit executables will not have the "64" at the end; they will just be hbmame.exe and hbmameui.exe .
