Memory cards for HP48 SX/GX
Antoine Mine' 2014
*****************************************************************************
*/
/*
HP memory cards can contain two kinds of objects:
- attached libraries
- backup objects (encapsulating any kind of object)
Attached libraries appear with a LIB attribute in imgtool's listing, and in
the global "LIBRARY" menu on the HP48.
Backup objects appear with a BAK attribute in imgtool's listing, and
in the relevant "PORTS" menu on the HP48.
Currently, we only support storing host files into backup objects and
retreiving backup objects into files.
For attached library objects in the memory card, we only show their name, but
cannot retrieve their contents.
To install a library contained in a host file, copy it with imgtool to
the card; it creates a backup object visible in the "PORTS" menu;
then evalue the object, store it into some port (e.g, 0 STO),
turn off the HP48 and back on; the library should now be attached and
visible in the "LIBRARY" menu.
(The process is similar to installing a library from a file you get
from the serial interface.)
*/
/*
HP memory cards have size from 32 KB to 4096 KB.
However, cards with size greater than 128 KB are seen as multiple ports of
size 128 KB on the HP48 GX. In imgtool, we see them as distinct 128 KB
partitions.
Unfortunately, at the moment, partitions do not seem to be supported in the
command-line tool...
*/
/*
Here is the format of backup objects (addresses are in 4-bit nibbles):
offset field size value
0 prolog 5 02B62 prolog for overall backup object
5 size 5 len total size in nibble without prolog
10 name length 2 nbcar object name, in characters
12 name 2*nbcar -
12+2*nbcar name length 2 nbcar same value as name length at 10
14+2*nbcar object - -
len-5 prolog 5 02911 prolog for inlined system integer
len - 1 0
len+1 CRC 4 - CRC from 5 to len
total length: len+4
i.e., the backup object is a container containing the object name
and two objects: the backuped object itself and a system integer
that contains the CRC.
HP48 host files start with a "HPHP48-X" header (where X can be any
single letter, which denotes a ROM revision and, implicitly, whether
the program is for the S/SX or the G/GX family).
When storing a file to the memory card, we strip the header and
embed the object into a backup object with the correct CRC.
When copying from the memory card to a host file, we extract the object
from the backup container, stripping its CRC, and add the HPHP48-X header.

To do:
- filter for text files
- read-write support
- report empty 'last modified' time if date field is all zeros
- report free space
- arbitrary sized images
- don't crash when strings in home block have non-ascii chars (charconverter does not apply)
- do something about bootblock bug in imgtool (commit aca90520)

@rem ----------------------------------------------------
@rem MAME Testing script
@rem (Windows only at the moment, sorry!)
@rem
@rem Initial setup of the script:
@rem
@rem 1. Create a fresh directory mametest/
@rem 2. Copy this script into it (mametest/runtest.cmd)
@rem 3. Copy a mame.ini with your ROM paths into it
@rem (mametest/mame.ini)
@rem 4. Copy a transparent crosshair cursor into it
@rem (mametest/cross.png)
@rem
@rem How to run a test:
@rem
@rem 1. Create a new subdirectory mametest/version/
@rem 2. Copy mame.exe into it (mametest/version/mame.exe)
@rem 3. Open a command prompt to mametest/version
@rem 4. Run "..\runtest"
@rem 5. Wait for all the tests to complete
@rem (Note one window will be opened for each CPU)
@rem
@rem How to generate a report:
@rem
@rem 1. Concatenate the summary files together:
@rem copy summary*.log summary-final.log
@rem 1. Open a command prompt to mametest.
@rem 2. Make sure you have run tests for at least two
@rem versions (mametest/ver1 and mametest/ver2)
@rem 3. Create an output directory (mametest/report)
@rem 4. Run "regrep report ver1\summary-final.log ver2\summary-final.log"
@rem 5. Upload the report directory to mamedev.org :)
@rem 6. Differing files are printed to stdout; redirect
@rem to create a list that can be run again via
