I am kindly requesting a x86 version of mame_libretro.dll v0.152, that includes the nagscreen patch option.
Has it been released in the past? I would really appreciate if someone uploads this, I can even donate via PayPal if it has to be compiled.
I am using an Atom mini PC with a locked 32-bit UEFI so 32-bit is my only option, while 0.152 still had the anti-nag option.
Also it appears that for some reason MAME 0.152 generally has better performance than later versions.
Regards, Nicholas
I would also like the same for version 0.149 which appears to run even more smoothly (on standalone MAME) on the system.
I would really appreciate if someone locates an older nightly or compiles it for me, I insist to donate for this 
We only have certain snapshots of MAME available, 0.078, 0.139 and 0.157, and it’s not just a matter of recompiling another version. They have to be ported to libretro, which is a substantial amount of work.
Thanks for the reply.
For my x64 setup I am using a MAME core that shows up as 0.152. Isn’t that version available?
Note that on my x64 setup I use MAME 2014 based on 0.152, I’m not sure if it was from a nightly but it works great.
After unsuccessfully testing the x86 version of RA on several PCs (ranging from Windows 7 32-bit to Windows 10 64-bit), I’m absolutely sure that no other x86 MAME core works except 0.78.
Is there a chance that I’m doing something wrong? It’s messing with my mind:
Games not running at all or running with crazy sound noise (try sf2.zip on 2014/2015 for example), while 2010 doesn’t run anything (just goes to the RA configuration screen).
A working 32-bit MAME “2010” or “2014” (or even 2015 git) core would be very, very welcome…
