 	* `S`: speed (CPU load, frame misses)
 	* `V`: video I/O reads and writes
 * `-nobinds` will disable most emulator keyboard bindings, allowing the X16 to see most keys and key chords.
+* `-nohostieee` will disable IEEE-488 hypercalls. These are normally enabled unless an SD card is attached or -serial is specified.
 * `-nopatch` is an alias for `-ignore_patch`.
 * `-nosound` can be used to specify that the audio subsystem should not be enabled in the first place. This is incompatible with `-sound`.
 * `-nvram` lets you specify a 64 byte file for the system's non-volatile RAM. If it does not exist, it will be created once the NVRAM is modified.

 * `-save_ini` will save Box16's settings to an ini file (at a default location, unless otherwise specified with `-ini`)
 * `-scale {1|2|3|4}` sizes the Box16 window to scale video output to an integer multiple of 640x480. (e.g. `-scale 2`)
 * `-sdcard <sdcard.img>` lets you specify an SD card image (partition table + FAT32).
+* `-serial` Enables serial bus emulation (experimental).
 * `-sound <device>` lets you specify a specific sound device to use. If given an improper device or no device, will list all audio devices and exit. Incompatible with `-nosound`.
 * `-stds` will automatically load all kernal and BASIC labels, if available.
 * `-sym <filename>` will load a VICE label file. Note that not all VICE debug commands are available. (e.g. `-sym myprg.lbl`)
