### BOX64_DYNACACHE

Enable/disable the Dynamic Recompiler Cache (a.k.a DynaCache). This option defaults to 2 (to read cache if present but not generate any). Not all architecture support DynaCache yet (it will have no effect then). DynaCache write file to home folder, and can grow without limit
Enable/disable the Dynamic Recompiler Cache (a.k.a DynaCache). This option defaults to 2 (to read cache if present but not generate any). DynaCache write file to home folder by default, and can grow without limit.

* 0: Disable DynaCache.
* 1: Enable DynaCache.
* 2: Use DynaCache files if present, but do not generate new one. [Default]

### BOX64_DYNACACHE_FOLDER

Set the folder for DynaCache files. Default is in XDG_CACHE_HOME/box64 or, it does not exist in HOME/.cache/box64
Set the folder for DynaCache files. Default is $XDG_CACHE_HOME/box64 or $HOME/.cache/box64 if $XDG_CACHE_HOME is not set.

* XXXX: Use folder XXXX for DynaCache files.
