Added region_ptr_finder， which works like shared_ptr_finder except it   finds a ROM region instead of a memory share. Unlike the already   existing memory_region_finder， these can be accessed without   any overhead (since it's a pointer directly to the data and not   to the memory_region object)， can be whatever data type you want   with no casting needed， and are strictly type-checked--if you have   a required_region_ptr<UINT32> the region has to be a ROM_REGION32   (or an implicitly 32-bit region due to belonging to a device with   a 32-bit bus) or the finder won't find it and will tell you why.   Basically， region_ptr_finders are strictly better than   memory_region_finders and all drivers using the latter should be   converted over [Alex Jackson] Converted many sound devices to use a required_region_ptr to find their   sample ROMs instead of looking up the region manually in device_start().   Note that this means that you can no longer get away with having e.g. an
