Hacking graphics
Due to ZXBox’s simple (but fast) scaling to the screen by dropping lines and columns
some games can become unplayable. It is possible to hack graphics to make them better
visible with the help of an utility such as the “Spectrum Graphics Editor”. Useful tools
can be found at the “World of Spectrum” site (http://www.worldofspectrum.org/utilities.

11.4 Applications
11.4.1 Battery Benchmark
The Battery Benchmark plugin enables you to test your battery’s performance whilst
using your player normally. Results can be submitted to the ZBatteryRuntime wiki
page.
How it works
Once loaded, Battery Benchmark runs in the background recording various informa-
tion about your battery to memory. A new point is written to memory every minute.
Every time the disk is accessed for any reason (such as refilling the audio buffer, open-
ing a directory or entering USB mode etc.) then the information in memory is written
to disk. Once the memory becomes full (after many hours), then the data are written
to disk anyway. This is done so that the data are not biased by excessive additional
disk accesses. The file is written to the root directory of your player and is called
battery bench.txt. The plugin will continue to log info until:
• Another plugin is loaded.
• The player is shut down.
• The battery is empty.
Benchmarks can be resumed if you accidentally load a plugin, or turn off your player,
so long as the log file battery bench.txt is not deleted.
Information explained
At the top of the battery bench.txt file is various information on how to use the plugin,
followed by the data themselves.
Time This column reports the total time of operation of the player. It is not the time
that you started the plug-in. If you have your player on for 5 minutes and then
start the plugin, it will start measuring from 5 minutes.
Seconds The same as Time, except measured in seconds.
