I finally had to punt and move from GameEx Arcade to GameEx. As soon as I did, the problems went away. The All Games and Favorites both show all games. I'm not sure what the limitation is within the GameEx Arcade implementation, because I used the gameex.ini from it as a template for GameEx. Thanks for all of the help.
I downloaded the support files for .189. Just to make sure, I am replacing all of the data in cabinets, cpanels, flyers, marquees, samples and snaps in addition to the mameinfo.dat and the .ini files. Still working on getting everything together. I should be able to give it a go tonight. Any suggestions for other .dat files?
Update: I completely replaced my ROMsets with new downloads. I've tried .180 and .189 versions. I also tried MAME64 .180 and MAME64 .189. I've also upgraded my ROM repair utilities. The issue has not been resolved. I can search for any ROM and run the game successfully, but they do not show up in the All Games or Favorites lists. I have tried deleting the listinfo.dat file as well. I am at a loss.
Here is my custom.ini. It is located in my MAME directory, in the folders directory. I've confirmed that games get added to it as I add them to my favorites list in GameEx. It is strange that the games do not show up on either the All Games list or the Favorites list. Other games, like Asteroids and Missile Command (and about 50 others) do show up in the All Games list and appear on my Favorites list when I add them. It is just a few that don't appear in either location.
Custom.ini
A split set. I've added sound files to A few ROMs, but for the most part, just keep with the standard split sets (world version, US version, Japan version, etc.)
That said, I checked each of these ROMs. Each individual ROM zip file appears to have a complete set of files. It doesn't look like they rely on any other ROMs/sets.
Oh...and I also went back to XXXXXXXX and downloaded the ROMs again, just to be sure. They all show green and good in Rom Center and all play in Rom Center and GameEx when I search for them and select play.
I am in the process of moving from Maximus Arcade to GameEx Arcade Edition. I am also using MameArcade64 with the Mame GameEx System Pack. I have installed ROM Center and have checked all of my ROMs with it and cleaned them up. Most of my ROMs work great, right from the All Games List and my Favorites list. Several (Pacman, Ms Pacman, Tron, Donkey Kong and other classics) don't show up. I can find them if I search for them. I can add them to my Favorites list. They are in the Custom.ini file in my Folders directory. I've gone over my GameEx.ini and set OnlyWorking=False, AllowImperfect=True and VerifyRoms=False. I have also set GameFilterOn=True and added the ROMs to DoNotFilterROMs (I've tried several variations of all these variables to no effect). I've attached my GameEx.ini in hopes that someone has either experienced this or can see what I am missing.
Thanks!!!!
