I rarely use the whole names of games where they have stupidly long subtitles, unless they differentiate between games (like "muscle bomber : insert stupid subtitle here")

Yes

No, its a type of hardware, single board PGM has the same componants (bar maybe an asic) as the cartridge ones, its just a different way of inserting roms.

Thanks for the other info,
