A mapper could switch just the vectors, but it would be very unusual. Do any?
In response to Myask's question in the 11011 edit summary, the PowerPak's NSF mapper does this. I don't know any other examples offhand, though. - Rainwarrior (talk) 15:45, 28 May 2015 (MDT)
- Arguably the PowerPak is not a mapper but a metamapper. On the other hand, I wonder how deeply (if at all) the Powerpak can emulate itself. On that note, metamapper seems like a useful term...or just another word for multicart mapper.Myask (talk) 16:09, 28 May 2015 (MDT)
- Well, I'm not talking about the whole PowerPak. I'm only talking about one of the mappers used for it. The NSF player mapper. Actually, I think Kevtris' hardware NSF player does the same thing, and there may be others. The TNS line of NSF playing cartridges do not; they simply replace the table in the initially mapped high bank of the ROM, and expects it to remain fixed (or else it crashes). NSF players are the only application I can think of that really require this. Game ROMs always have their own bank-appropriate vector tables.
