I find it amusing that he's apparently configured the rom path for MAME no problem but can't figure out that MESS is configured exactly the same way.
They can't be configured the same way. If they could my ume.ini configuration would just work. Oh, that's right...it does.
When are you mame devs going to stop forcing people to use your crappy command line software?
O/T, when did ume happen, anyway? I never heard of it until I saw qmc2-sdlume in the last binary package. It works very well, btw. Congrats to all involved.
