EMUlaunch Version 1.5.2 has been released. Its mostly a compatibilty fix for users using SDLMame. Somewhere between 0116 and 0122 the launch script used by EMUlaunch was not working. Thanks to Mark LaBonte for the bug report and fix.
Also, a small reminder to those who use SDLMame, if you want to use an .ini […]

Crap, seems that somewhere between SDLMame 0117 and 0122 (I suspect 0121), launching games through applescript has broken. An apple script command run in Script Editor:
do shell script “/Applications/MAME/mame0122 /Applications/MAME/roms/game.zip”
is no longer equivalent to
/Applications/MAME/mame0122 /Applications/MAME/roms/frogger.zip
run in the terminal.
For now I suggest sticking with SDLMame 0116 or using MAME OS X with EMUlaunch.

A host of bug fixes and new additions have been made to EMUlaunch 1.5.1. Most noticeably, EMUlaunch now supports screenshots created by MAME OS X. By default, EMUlaunch looks for the nameoftherom.png inside of the user selected screenshots folder. Now if it does not find it it will now also check ~/Library/Application Support/MAME OS X/Screenshots/romname/0000.png. […]

EMUlaunch has been updated to v1.5 with the following changes:

Layout customization options (more options in regards to font size and background bevels to come)
Option for second artwork
Option to remove dock
Updated 512px icon for Leopard
Improved mutli resolution support, especially for vertical resolutions such as 1200x 1920 and legacy resolutions such as 6410 x480
Background image now scales […]

Fixed bug which prevented launching games in MAME OS X if the rom was located in a sub directory of the main roms folder. Thanks to Dave Dribin for the quick response on the correct syntax for doing this.
Updated MAME background image

I’ve just posted a video showing new users how to setup EMUlaunch. It covers most of the issues regarding how to setup your folder structure and some other random tidbits. This was a one take shoot so sorry about the background music and traffic.

This update should fix the problem with EMUlaunch not being able to switch to the next console in some instances
Minor interface updates

A video tutorial will be added to this site soon to help those having trouble setting up EMUlaunch.

update I added a video tutorial to the FAQ page.

Incorrect stretching of background images has been fixed
ListXML is now included with EMUlaunch, as a result the MacMAME analysis or user created listxml files are no longer needed.

Special note about list xml.
In the past EMUlaunch has required the user to create a MacMAME analysis file or SDLMame -listxml file in order to properly match […]

Support for SDLMame and Mame OS X using -listxml file which can be generated using SDLMame.
Better multi-resolution scaling
Interface changes (larger fonts, no scroll bar, somewhat closer to a front row look if you disable backgrounds and use the zoom mode)
Faster scrolling
Cached xml files for all systems (this should help going back and forth between systems)

Processor use when EMUlaunch is in the background has been significantly decreased. EMUlaunch now hovers around 0-2.5% (on my Powerbook G4 1ghz) when in the background after it has launched a rom file. Download version 1.3.1 here http://emulaunch.com/downloads/
