Quick Reference

This chapter covers all the menu items in Sweet16, discussing what they do.

File Menu

Mount Image

Lets you select a disk image file to mount, using a standard BeOS file panel. In the bottom-right corner of the file panel, there's a "Mount as read-only" checkbox. If you check this, the image will be mounted as if the disk were locked.

You can select multiple disk images to mount if you wish.

Mount Floppy

Mounts the physical disk in the device /dev/disk/floppy/raw; this is the main 3.5" high-density floppy drive. Hold down the control key while selecting this option to mount the disk read-only.

Mount Physical Disk

Pops up the Mount Physical Disks window to let you select a real disk device to open.

Eject

The Eject option pops up a submenu allowing you to select a drive to eject. Empty drives are greyed out and can't be selected.

 

Create

To create a disk image, simply choose the size of disk image you'd like to create. A BeOS save file panel will appear; enter the name of the new image file (don't forget the appropriate extension for the type of file you want to make), and Sweet16 will create the image file.

Record Movie... / Stop Recording

You can record movies of your Apple IIGS video (but currently only in the larger screen mode; if you're in small video mode, recording doesn't work)! To begin recording, choose Record Movie. The filepanel that appears contains several additional menus in its menu bar:

Format

Choose the movie file format you want to save into. This menu will contain a list of all the file formats you have Media add-ons for, such as AVI or QuickTime.

Codec

Choose the codec you want to use for compressing the video. Codecs include Photo-JPEG, Indeo, and the like. If you don't want to compress the video, choose the Raw Video codec.

Quality

Choose the compression quality. The lower this quality setting, the smaller the resulting movie will be, but the lower-quality the video will be.

Frame Rate

Choose the number of frames of IIGS video to write per second. The Sweet16 video display is 60 frames per second, but you can control the frame rate of the movies you reate. The lower this number, the smaller the movie file will be, but the more jerky the video will appear.

Note that creating movies is a very CPU and disk-intensive process. Unless you have an extremely fast machine, you'll have a very noticeable slowdown of the emulator while creating movies. To get best movie-creation performance, use a high-speed disk drive (a striped disk is best).

When you're done recording, choose "Stop Recording" from the File menu.

Currently, you can't get audio recorded into your movies.

Quit

Quits Sweet16. An alert will ask you to confirm first. Notice how the IIGS keeps running while the alert is up. Ah, the power of BeOS.

Edit Menu

Copy

The Copy item captures the current Apple IIGS video display into the BeOS clipboard as a graphic clipping.

Capture Text

Captures the current Apple IIGS text screen into the BeOS clipboard as a text clipping. You can then paste this clipping into a text editor.

Capture Picture

Does the same thing as Copy; copies the current Apple IIGS video display into the BeOS clipboard as a graphic clipping.

Setup Menu

Preferences

Contains options for configuring Sweet16. There are several panels, accessed via tabs, that provide a variety of options.

CPU Core

The CPU Core panel provides options for configuring the Apple IIGS 65816 processor and memory settings.

The Memory slider lets you configure how much RAM your IIGS should have (from 1 to 8 MB). The Speed slider lets you configure the speed your IIGS should run at when at the Fast speed setting. This speed is only used if speed control is enabled. ZipGS emulation can also be enabled and disabled here; it only works if speed control is also enabled.

Disks

The Disks panel provides options for configuring disk emulation.

Currently, the only option available here is the option to turn on or off cacheing of floppy disk writes. By default this is off; however, your disk writes are much faster with cacheing on (the IIGS will write into a RAM cache, and a background BeOS thread will write to the floppy while you continue to use the IIGS). There is some additional risk to using the write cache (because if an error occurs, the IIGS will never know about it, because it thinks the write already succeeded), which is why this is off by default.

Opens the preferences window. Currently, all you can do in the preferences window is select a joystick to use.

Sound

The Sound panel lets you configure audio performance.

The amplitude scaling option lets you turn on or off the graudual decrease in volume of the IIGS sound oscillators as more and more oscillators are playing. Turning this scaling off substantially increases audio volume when playing music sequences; however, this shouldn't generally be necessary.

The "Play all sounds as mono" option assumes that all sounds are monaural, and forces them play out both speakers. You usually won't use this option; the only time you'd use this is if you tend to run programs that only use one speaker.

Joystick

The Joystick panel lets you select a joystick to use as your IIGS joystick.

Before using the Joystick preferences, be sure to visit the BeOS Joysticks preference application and configure your joysticks. Then you can select your preferred joystick from the list in the Sweet16 Preferences window, as seen above. Click OK to save your selection.

Joystick Support (Shift-Alt-J)

This option allows you to turn on and off joystick support. Be sure to configure your joystick before turning on joystick support. If there's a checkmark next to the menu item, joystick support is enabled.

Sound Support (Shift-Alt-S)

Toggles on and off sound support. Please read the warning about disabling sound support.

Full Screen (Shift-Alt-F)

Toggles between full screen mode and window mode. In full screen mode, Sweet16 increases the priority level of its threads, so it runs a lot faster.

Pause (Shift-Alt-P)

Pauses or unpauses the emulator.

Reset

Issues a Control-Reset to the Apple IIGS.

Restart

Reboots the Apple IIGS.

Window Menu

Disks

Displays (or brings to the front, if it's already open) the Mounted Disks window.
