#### 7.1.7.1 C64 system ROM resources

`BasicName`

  String specifying the name of the Basic ROM (default `basic`).

`ChargenName`

  String specifying the name of the character generator ROM (default `chargen`).

`KernalName`

  String specifying the name of the Kernal ROM (default `kernal`).

`KernalRev`

  String specifying the Kernal revision. This resource can be used to control what revision of the C64 kernal is being used; it cannot be changed at runtime. VICE is able to automatically convert one ROM revision into another, by manually patching the loaded image. This way, it is possible to use any of the ROM revisions without changing the ROM set. Valid values are:

  `0`

    Kernal revision 0;

  `3`

    Kernal revision 3;

  `sx`
  `67`

    Commodore SX-64 ROM;

  `100`
  `4064`

    Commodore 4064 (also known as “PET64” or “Educator 64”) ROM.
