Emulator runs Extremely Slow on some hardware (Atari 7800 & Arcade NBAJam)

[Gitweazle]

When I run an Atari 7800 game on MAMEHub it will run very slowly (~30%), but in MESS 0.149 and 0.154 they both run at 100%. The slowdown happens both with and without the -server argument.

I cannot seem find anything in particular in the logs.

I am not sure if it is related, but the same thing is happening with NBA series on the Arcade (NBA Jam Tournament Edition and NBA Hangtime). The games run at 25-50% speed.

They run 100% in MAME 0.149 / 0.154 & UME 0.154.

(thanks to RichardCranium for finding this)

Can you check the emulator log and see if there are a ton of prints in
there?

Here is my log without anyone connected:

It doesn't look too different from other games that run at 100%

Hmm, can you run manually running csume.exe without the -client or -server
flags? Under these conditions it should be the same performance as regular
MAME. Let me know either way.

Without -server argument using command prompt it runs bad as well: ~40% constantly.

Another user has the same slowdown in MAMEHub (just to verify it's not just me).

[MisterTea]

Hmm, it must be the symbols then. I have MAME compiled with symbols so
that if there is a crash people can send me a stack trace.

For me to fix this, I need to build grabbing csume.exe into the MAMEHub UI
itself and give people the option to grab a version without symbols, but if
it crashes you are on your own.

Did some more testing, it happens on all games using the same hardware as NBA Jam, this includes:

Smash TV (smashtv.zip)
Total Carnage (totcarn.zip)
Trog (trog.zip)
Mortal Kombat 2 (mk2.zip)
Ultimate Mortal Kombat 3 (umk3.zip)
WWF: Wrestlemania (wwfmania.zip)
etc.

i have the same problem

[MisterTea]

Try this binary and see if it makes a difference: http://10ghost.net/MAMEHubDownloads/csume.7z

[Gitweazle]

That version still has the slowdown for me.

[MisterTea]

We talked about this issue today, what was the consensus? Is it a 0.154 issue or a mamehub issue? Also, please check the binary I just pushed and let me know if it's still there.

[Prinygod]

Consensus is its not a ..154 problem. After the conversation I tried vanilla 154 ume and it was fine and then cat tried it again and it was working normally for him as well

Hi ! I'm also having the same issue running MAMEHub on Mac OS X Yosemite.

[Prinygod]

the problem has been fixed with the new version closing

[Gitweazle]

Confirmed!

Awesome. Thanks for fixing this one!
