2.3 Saving a frozen program

can install a

[SYSTEM RESET]

key in the Atari as described in section 1.5.2. The interrupt

triggered by this key can by no means be suppressed, so there is no counter measure

against the TURBO FREEZER anymore.

When a frozen program is resumed with

[Shift]

[SPACE]

, the player/missile collision

registers are cleared before control is handed over to the frozen program. Usually this

function is not required, but in some games this prevents losing a life immediately after

resuming. When loading frozen programs the same function is also available. Simply press

[Shift]+[E] / [C] / [X] / [W] / [A] to apply it.

When a frozen program is loaded from disk, cassette, freezer RAM or RAM extension it

is resumed by default. When loading a frozen program with

[Control]

[E]

[C]

[X]

[W]

[A]

it will not be resumed automatically. Instead you stay in the freezer and can for

example change memory locations before resuming. This comes very handy if you search

for the memory location that contains the number of lives, the amount of energy and so

on. To this end you can freeze the program and save it immediately. Then you change

the memory location and resume the program. If you used the wrong memory location,

simply activate the freezer and load the frozen program with

[Control]

[E]

[C]

[X]

and try the next memory location. This way you have the same starting point and you

don’t have to worry about undoing the previous changes.

2.3 Saving a frozen program

The functions

[S]

[F]

[R]

can be used to save frozen programs to external mass storage

like cassette or disk (

[S]

key), to the RAM extension (

[R]

key) or to the freezer RAM

(

[F]

key). When using

[S]

a submenu will prompt if the frozen program shall be saved to

cassette, as a boot disk or as a single ﬁle. Insert a cassette resp. disk before conﬁrming

your choice. When saving as a single ﬁle to a disk an additional menu will prompt for the

ﬁle name.

Caution:

When you save the frozen program as a boot disk, the disk that is present in

“D1:” will be overwritten directly. All data possibly present on the disk will be lost in this

case.

If you simply press

[RETURN]

without entering a ﬁle name, the ﬁle name

CORE

for “core

dump” will be used. As a special feature wild cards can be used to overwrite an existing

ﬁle. If you omit the

D1:

D2:

etc. at the begin of the ﬁle name,

D1:

will be used

automatically. The freezer supports up to 8 disk drives D1: to D8:.

In order to achieve the maximum possible speed the freezer menu is sometimes disabled

during I/O operations. By accepting that the screen may “jump” when it’s switched back

on again, saving to the RAM extension only takes half of the time, what legitimates this

dirty method.
