I just started playing around with mGalaxy since it's the only one I like that runs on my XP machine.
With all frontends before, I was lacking a way to filter by game age. I really want to be able to run all my games but when I just browse games, I just want to see some wow titles with huge sprites.
So I made small .java program that parses the enriched xmlout.xml from mgalaxy and outputs 3 .xml files with selected games.
You just need to create 3 systems by copying the mame system (C:\Program Files (x86)\mGalaxy\Data\UserSystems) changing the keys in the folders and the UserSystems.xml (I did Multi-system [MAME]-I2zbZe7o, 80 Multi-system [MAME]-I2zbZe8o, 70 Multi-system [MAME]-I2zbZe9o) and replacing the games in the xmlout.xml with the corresponding output file, leaving the header and dbase elements as they are so make this
Code: Select all
<?xml version="1.0" encoding="utf-8"?>
<dbase name="Multi-system [MAME]" version="0.200 (mame0200)" update="8/18/2018" comment="">
</dbase>
My Java program - feel free to use and change as you wish.
One word of advice though:
All my systems use the same video and snapshot directories now but each uses only a part of it. I'm afraid to update the lists now because I'm afraid each part-system will delete the files of the other systems -.-
I think I should improve it so it also divides the files of the asset directories into 3 asset directories
Now if anyone finds a way to put different icons and texts to my 3 different mames, that would be awesome ^^
