What is Xpand?

Xpand is an OS patch to use as Archive Memory the 1728kb (~1.69Mb) of
FlashROM reserved for the Flash Apps.
2688kb (~2.62Mb) of Archive Memory will be usable after the patch.
(Remove 64kb from these figures for AMS 3.01, and 128kb for AMS 3.10
and higher).

Using Xpand

THE PATCH WILL BE IRREVERSIBLE. The only way to remove its effect is to
send a new OS to the calculator.

Run Xpand once from the Home screen on a stable calculator (without
any resident program installed, preferably after a reset).
The Garbage Collection made at the end of the patch can take a few
seconds. You need to patch the OS only once: you will not need to run
Xpand after each reset.

You can check that your archive memory has been 'expanded' by running
getconfg() in the Home screen: the value of 'Archive size' at the end
of the list should be higher than before (see 'What is Xpand?' above).

Once the OS is patched, its checksum is invalid; you will not be able
to send the OS from your calculator to another V200.

Caution, you may lose some of your archived files when sending a new
OS to the calculator once Xpand have been installed. Backup your files
before flashing the calculator, and patch the new OS after its

What was wrong with version 0.1?

Xpand has been removed from distribution for 9 months, because of an
important bug that made the calculator crash when trying to install a
lot of Flash Apps with Xpand installed.
The problem has now been fixed, Xpand should not interfere anymore with
Flash Apps installation.

The execution protection in FlashROM memory seems to be buggy on the
Voyage 200 when trying to protect a part of the range address
0x400000-0x500000. Perhaps this is why TI has created the limit of
available archive memory that Xpand breaks (for the same reasons as
the limit on TI89/TI92+ HW1 calculators broken by MaxMem).

An interesting feature added by version 0.2 to correct the problem is
that the execution protection in FlashROM memory has been completely
removed. Anything can be executed in archive memory after Xpand's
