I use DBGL for when I want to casually play dos games easy and make some database of them. It's what I use to have a self-contained collection that doesn't rely on absolute paths.
I tried to like Dfend Reloaded, but it has some way of crashing the DOSBox it ships with, and can't be compatible with the dosroot I use with DBGL, and there seems to be integration into searching shady abandonware sites right in it, as if they were the only source of DOS games ever, which is odd because it contradicts their 'legal only' views with freeware/shareware dos game bundles on site.
