I am working on implementing a new bankswitching method for my Da Vinci 
project and need technical assistance from real VCS programmers.  Basically 
the VCS program has to have access to 2000 16 character names, 32K of data.

I was thinking:

    0x1000 - 0x1BFC  straight normal non switched VCS program memory.
    0x1BFD           VCS program writes index high byte of selected game
    0x1BFE           VCS program writes index low byte of selected game
    0x1BFF           Writing X here would load X data bank.
    0x1C00 - 0x1DFF  Data bank X read access.  32, 16 character names.
    0x1E00 - 0x1FFF  Data bank X write access.
I am trying to come up with a way that users can write game select programs 
that have access to Da Vinci's file list.  I am not suppling this program, I 
have no VCS programming experience, but I want it as an option for people who 
are capable to writing a program that will be able to select and edit games on 
their VCS.

Will the method above be suitable and efficient enough for a program to 
display the 16 character file names and allow a user to select one.

If you are unfamiliar with Da Vinci, check this:

Please feel free to correct me if I am way off base on this one.
