!Help for SACache
Written by Owain Cole
Sun 09th February 1997
as a production for
Visions of the Impossible
NB This program will only be of use if you have a StrongARM fitted. It
doesn't check for the presence of a strongARM only RiscOS3.7
SA Cache
=------=
So you have a mighty beast of a processor quietly humming under the lid of
your RiscPC, but unfortunatly, the games writers of yesteryear were not
prepared for such a vast increase in processing power. All your games run at
the speed of light, so StrongGuard suggests that you turn the cache off.
Not a good idea. This worked on ARM6's and 7's but turning the cache on a
strong ARM cripples it totally, in fact it runs slower than an ARM2.
An as-yet undocumented feature of the *Cache On|Off command is that there are
several other perameters that you can use to turn specific parts of the cache
off. These are the Instruction cache, the data cache and the write cache. The
way to turn them on and off it to specify which you want to leave on, the
rest are turned off. eg
*Cache ID : This turns the Instuction cache and data cache on, and
turns the write cache off.
*Cache DW : This turns the Data and write cache on and the
instruction cache off.
I assume you can follow the pattern. But, this still leads to the problem of
how do you turn the cache (partly) off, then run the game. Cos when it quits,
it's going to take about 3 minutes to redraw the screen again. Before you can
turn it back on again at the command prompt or on a task window.
This is where SACache comes in.
If you drag a file/application to it, then it will be run with the cache set
as specified under the "Cache Off" menu, and when it quits, then the cache
will be turned on again.
Ah, I here you say, that's easy to do, but what about if the game has a
desktop front end?????????? Well, hopefully I've gotten round that by using a
nasty wimp filter on it. Hopefully it should work!!!!!
Not really very complicated is it.
What if I want to change the cache settings on-the-fly....
=--------------------------------------------------------=
SACache also produces a module (which can be saved off and run without having
SACache loaded up, which can turn the cache on and (partly) off by pressing
several key compbinations which can be set using the main window. Nice hey!
Oh, and changes in the options in the main window are only reflected in the
modules response after you have clicked on the Create/Alter Module button, or
saved the module.
NB A standard shift+F1(or F2) module is automactially created when you run
SACache.

This is a public domain program, which means you can rip the code out, use it
for dodgy purposes and copy it around like there's no tomorrow. I take no
responsibility for this program actually working, and not just eating up your
harddrive.
