Title: Issue with CPWizard and GroovyMame
Post by: Banacek on January 12, 2013, 08:35:54 pm

CPWizard ver. 2.38
GroovyMame ver. 64_0146.013f
Mame64 ver. 0.146
Windows 7 SP1

Followed the instructions for CPWizard here: http://headsoft.com.au/index.php?category=cpwizard (http://headsoft.com.au/index.php?category=cpwizard) (under Method 1)

With Mame64, CPWizard works. It fires off the pause to Mame and when you exit CPWizard it goes back to Mame. With GroovyMame, it never pauses, and when CPWizard quits the screen is frozen.

I've tried Method 2 (show when pausing Mame), and CPWizard works, but when you exit the screen is frozen.

Has anyone gotten this to work? Thanks!

Hi Banacek,

GroovyMAME by default updates the screen on a separate thread of execution. The synchronization is very delicate and it's a terrible idea to mess with it from an external application because that can easily induce a dead-lock. Disabling -multithreading will revert this behaviour to MAME's standard so it fix this problem.

Ok thanks! I'll switch it over when I get home.
