# Multiface 2 general file information

The Multiface can save two file types:

- A screen file,
- A Memory dump,

The screen file is always &4080 bytes in length, and consists of the uncompressed screen and program code to initialise the mode, colours and dimensions of the screen.

The memory dump has the following files (e.g. save filename = "CHASEHQ"):

CHASEHQ.BIN |  | loader file (note 1)
CHASEHQ1.BIN |  | memory data (base 64k - &4000-&7FFF)
CHASEHQ2.BIN |  | memory data (base 64k - &8000-&BFFF)
CHASEHQ3.BIN |  | memory data (base 64k - &C000-&FFFF)
CHASEHQ4.BIN |  | memory data (base 64k - &C000-&FFFF)

The following will only exist, if the second memory bank has not been erased (the second bank can be erased using a option from the Multiface 2 menu):

CHASEHQ5.BIN |  | memory data (second bank of 64k - &0000-&3FFF)
CHASEHQ6.BIN |  | memory data (second bank of 64k - &4000-&7FFF)
CHASEHQ7.BIN |  | memory data (second bank of 64k - &8000-&BFFF)
CHASEHQ8.BIN |  | memory data (second bank of 64k - &C000-&FFFF)

Note:

- The loader contains a short program to enable the Multiface 2 ROM and execute the memory dump restore function of the Multiface 2 and the state of the computer when the "stop" button was pressed. (CPU registers, colours, mode, screen dimensions and other hardware state)
- The memory dump is not stand-alone. The Multiface 2 is required to use the memory dump.
- The remaining files represent 16K of RAM each and they are compressed. (in this example CHASEHQ1.BIN, CHASEHQ2.BIN, CHASEHQ3.BIN, CHASEHQ4.BIN and if they exist CHASEHQ5.BIN, CHASEHQ6.BIN, CHASEHQ7.BIN, CHASEHQ8.BIN contain the RAM data in compressed format).
- The maximum size of each file is 16K.
