Simple question, probably not too simple an answer.
How would I go about adding all the various blitters / screen filters I've seen in different compilations of MAME, and other emulation programs? Like Kscale (especially) 2xSai/Super2xSai/SuperEagle. Also looking to find where to set an option for default BIOS to be selected, via the "default game options... > miscellaneous" or whichever tab there.
I've just begun to search for how to do this, if I find it somewhere else I'll post it here for any more curious minds as well. If I don't get any replies by the time I can find the information anyway
