Selecting this item will cause the emulated Jaguar’s display to be averaged, resulting in a screen that looks slightly blurry—more like what you would expect to see if the Jaguar was hooked up to a television. This is an aesthetic option that some people prefer; you may or may not like it.
+Selecting this toolbar button will switch the display into full screen mode; selecting it again will switch it back to windowed mode. This option can also be activated by pressing the F9 key on your keyboard. Note that on monitors with a wide aspect ratio that Virtual Jaguar will still display its virtual screen in a 4:3 aspect ratio—this is normal and expected.
+Pause does the same as the toolbar button; see the “Pause” toolbar button description for details.
+Frame Advance causes Virtual Jaguar to run for one frame (1/60th of a second for NTSC, 1/50th for PAL), and update the screen. This function can also be activated by pressing the F7 key on your keyboard. This option only works when Virtual Jaguar is paused.
+Insert Cartridge... does the same as the toolbar button; see the “Insert Cartridge” toolbar button description for details.

Hovering over a letter on the picture of the Jaguar controller will highlight it; clicking on the letter will let you redefine that key. If you prefer, you can define all the keys at once by clicking on the “Define All Keys” button. It will then step through each button on the controller, one at a time, and wait for you to press the key that you wish to set it to. You can exit the key redefinition process at any time by pressing the Esc key on your keyboard.

+ +NOTE: For gamepads to be detected, they must be connected to the computer before starting Virtual Jaguar.
ABS to load is the path to a Jaguar executable file that will be loaded in the Jaguar’s main RAM. This file must have valid headers, otherwise Virtual Jaguar won’t be able to load it. Assuming the file exists and has the correct headers in it, it will be loaded and run when Virtual Jaguar is first run.
+Also, when in Alpine mode, extra toolbar buttons are defined (also found under the extra “Debug” menu):
+ +This window lets you inspect Virtual Jaguar’s emulated memory space. The PgDn key will advance the top of the window’s memory location by 480 bytes, and PgUp will go back by the same amount. The Plus (+) key will advance the top of the window’s memory location by 16 bytes, and Minus (-) will go back by the same amount. Entering a memory location, in hexadecimal, in the edit field and pressing the Go button will display memory from that location. It can be dismissed by clicking on the “X” in the upper corner of the dialog, or by pressing the Esc key on your keyboard.
+ +This window shows the state of the various CPUs in the emulated Jaguar. It can be dismissed by clicking on the “X” in the upper corner of the dialog, or by pressing the Esc key on your keyboard.
+ +This window shows the current state of object list that the Object Processor is pointing to. Note that most of the time, this will likely show an object list that has had its objects processed. It can be dismissed by clicking on the “X” in the upper corner of the dialog, or by pressing the Esc key on your keyboard.
+ +This window provides a disassembly of 68000 opcodes. It can be dismissed by clicking on the “X” in the upper corner of the dialog, or by pressing the Esc key on your keyboard.
+ +This window provides a disassembly of RISC opcodes. It can be dismissed by clicking on the “X” in the upper corner of the dialog, or by pressing the Esc key on your keyboard.
+The aforementioned options will only work when Virtual Jaguar is run in Alpine mode, that is, when the --alpine flag is passed in. If you do not pass in the --alpine flag, Virtual Jaguar will run as it normally does, i.e., as a stock Jaguar, and nothing will be loaded by default.
