It has been quite a while since looking at updating anything within GameEx, however upon seeing Nintendo Game & Watch are now within MAME I decided it was time to update.
I originally had MAME 0.184 installed and running. I downloaded a merged ROM set for 0.214 along with the extras (snaps, etc). I installed MAME 0.214 to a new folder and set it up and copied the ROM files in, etc.
I then renamed my old MAME folder and renamed the new one to match what the old one was. Went into GameEx and did an update. It went through the process of reading MAME game list, catver, etc. However once complete and I go into all games, the Game & Watch ones do not appear. If I exit and run MAME and find them in the list there, they open and play without issue.
I've gone into the settings and gone through and turned off any filters and then gone into GameEx and run an update again with the same results.
I also made a custom list just for the Game & Watch games and when I go into that it just says there is nothing to display.
Hoping someone can point me in the right direction of what I may need to do or what I have missed to get these displaying. It is also making me wonder what else may not be showing up that is new between the versions I've run.
And one final thing, is there any update on being able to read in the newer formatted history.xml file? It appears as thought the dat file is no longer produced. When looking through the forums I did see a question about it back in October 2021 but am not sure if there is anything further.
Cheers.
