i found out romcenter is obstinate about absolute path... well at least regarding the rdt database... i manually set it as a relative path, software can find database, but when i close it... it does memorize the path as absolute.
giving the option to use relative path add versatility to the software... especially if roms and romcenter are in the same place (or share same main folder)
for example if i rename Console Snes into Console snes 2012 (and both roms and romcenter are inside... i dont need to modify the path)
or if i move the Console snes folder from c: to d: i still dont need to change the path
so just thing about it... using relative path, or preserving relative path once someone manually put it
