I honestly don't know about it but if you think it's alright that's good )

I'm starting to add some case artwork views as requested.. I'm only going to add the top of the cases with the logos on. So far there's Donkey Kong, Oil Panic and Mickey & Donald

Don't hold your breath, but if a couple percent speed bump is all you need this might just do the trick.


In the majority of my tests, mame binaries compiled on this odroid-n2 with ARCHOPTS=-march=native win by a sliver. It's such a tiny margin (typically 0.1% - .25%), and there are cases where the reverse is true. I couldn't fault someone for suspecting statistical noise. Same outcome whether compiled with gcc7 or gcc8. Worth a shot.

Code
# gcc -march=native -E -v - </dev/null 2>&1 | grep cc1
 /usr/lib/gcc/aarch64-linux-gnu/8/cc1 -E -quiet -v -imultiarch aarch64-linux-gnu - -mlittle-endian -mabi=lp64 -march=armv8-a+crypto+crc -fstack-protector-strong -Wformat -Wformat-security

# gcc -E -v - </dev/null 2>&1 | grep cc1
 /usr/lib/gcc/aarch64-linux-gnu/8/cc1 -E -quiet -v -imultiarch aarch64-linux-gnu - -mlittle-endian -mabi=lp64 -fstack-protector-strong -Wformat -Wformat-security


I'll also note here that I have best testing mame's maciici emulation performance, compiled with gcc7 vs. gcc8, and gcc7 is winning by a margin of nearly 2%. No net improvement for me, as I have been using gcc7 from the start.

So once we have these equations, we can make a spreadsheet, and with a bit of trial and error, deduce what the original values of the paddles when it was calibrated.

The values in VWCALDA8.VER are 58,20,193,115,84,20,70,70.

We find that PDL0 was A=250 and B=655, and PDL1 was A=482 and B=885.

From a cool article on the versawriter, I now know the length of the arms: 6 inches each and the dimensions of the main board: it measures 12" vertically and 13.5" horizontally.

MAME 0.214 crashes at startup on Catalina Carbon 10/16/19 10:08 PM
Here's the output:
Code
dyld: Symbol not found: __ZTINSt3__112bad_weak_ptrE
  Referenced from: /Applications/Emulation/MAME/./MAME
  Expected in: /System/Library/Frameworks/AudioToolbox.framework/Versions/A/AudioToolbox
 in /Applications/Emulation/MAME/./MAME
zsh: abort      ./MAME


I built it using a beta of Xcode 11 before Catalina was released. Could that be the source of the crash?
