 Bank-switching for dual bank binaries is now supported by ParaJVE.

If the size of the loaded ROM is greater than 32K, lower or equal than 64K, and has a valid Vectrex Cartridge header at offset $8000, the the emulator automatically switch to dual-banks mode.

That is, it selects bank 1 ($8000..$FFFF) when the 6522's PB6 line is HIGH (the default after a reset/reboot), and bank 0 ($0000..$7FFFF) when it is LOW.
