First version of MAME that was 64-bit?

[DeLuSioNal29]

Anyone know the answer to this?  I tried searching on Google and on the MAME site and they only seem to have the 64 bit version available on the current build, not on older version.

What's the first version of MAME that was 64-bit?

I'm looking to downgrade my MAME version to my older 32 bit version of MAME .119 but my OS is now 64-bit.  It seems to run great, but was just curious if there was a 64-bit version out there.  Can't hurt to double-check.

Thanks in advance!

Think it might have been 120 according to this post on EmuTalk.net ( http://www.emutalk.net/archive/index.php/t-42288.html ):

As of this release, I am officially producing a 64-bit native Windows binary along with the usual 32-bit builds to help encourage more testing of the 64-bit native code. For the most part, games run at least as well as the 32-bit versions, and some run significantly better thanks to the architectural improvements of native 64-bit mode.
Full list of changes here (http://mamedev.org/releases/whatsnew_0120.txt).

Man, looks like I just missed it.   

However, it's not that far off from version .119 so I may update the romset and recompile to .120.  Thanks for the info.

P.S. - I am running Generic Artwork on Vertical games, which is another reason I want to revert back to an older version, since this stopped working from .140 forward.  Read more here:  http://mrdo.mameworld.info/mame_artwork_generic.php

I'm using 0.149 with the added artwork files so that each game shows it's bezel when run (found a 9.5+\- GB download of the artwork (with Flyers,Snapshots,Cabinets,Marquees, CP, etc.) for the new release and updated my roms also and so far looks like most games work properly with the bezels though I do set it to Cropped so the game is full size rather than scaled down to fit inside the bezel as that makes the game a bit small on my 23 inch 16x9 monitor.
Here's an example of a few games and one of what it looks like if using Full instead of Cropped in the settings :

Haven't had a chance to update my bartop with a 15" 4:3 monitor yet to see what it looks like on it but this does help my desktop monitor look much better when playing on it.

You can run 32-bit MAME on a 64-bit Windows OS.

You can run 32-bit MAME on a 64-bit Windows OS.

but 64 bit mame will run better

Mame 0.106 was the very first to have an experimental 64-bit build compile option

MAME 0.120 was the very first to have an official 64-bit binary.

If you go too far back the 64-bit builds are pretty unstable tho, a fair bit of the code hadn't been written with 64-bit in mind at that point and the compilers weren't as good either.

These days they should be considered the primary offering tho, for the majority of emulated systems you get a 20-25% speed boost without doing anything vs. a 32-bit build.
