Custom Keymap This menu allows you to map one of the Spectrum keys acces-
sible through the plugin’s virtual keyboard to each one of the buttons.
Quit. Quits the emulator..
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.
html).

The Battery Benchmark Plugin enables you to test your battery’s performance, while
making normal use of your player. Once loaded it will run in the background (TSR plu-
gin), reading various info about your battery while you use it. Once you finish your ses-
sion you can find the benchmark output data in a file on your player /battery bench.txt.
