AMX Mod X only apply addons/amxmodx/configs/maps/prefix_*.cfg for maps with underscore as prefix (de_*, fy_*). What about the maps that don't have underscore?
I would like to suggest to loop through all the prefix_*.cfg files and compare if the map name starts with what the value of * is and apply the configuration if it is a match.
There are plenty of maps that don't use underscore as prefix.
EDIT:
Noticed plugins-*.ini already have this behaviour, why not for map configs as well?
