KEGS for Sega Dreamcast

(An Apple IIgs emulator for Sega Dreamcast)

In the emulator
- The Analog Thumb Pad can be used as either the Apple II joystick or the Apple II mouse.
- The Directional Pad can be used as the Apple II joystick.
- The A Button is Apple II joystick button 0.
- The B Button is Apple II joystick button 1.
- The X Button is either a user definable keyboard key when the Analog Thumb Pad is in joystick mode, or the mouse button when the Analog Thumb Pad is in mouse mode.
- The Y Button is also a user definable key.
- The Start Button toggles into and out of the Configuration menu, effectively pausing the game.
- If a controller becomes unplugged, the emulator enters the Configuration menu, effectively pausing the game.
In the Configuration menu
- The Directional Pad moves through the menus (arrow keys).
- The A Button is Enter (return key).
- The B Button is Back (esc key).
- The X Button is eject (e key).

Squeezing Trigger L will change the emulated speed to 1.0 MHz.
Squeezing Trigger R will change the emulated speed to 2.8 MHz.
Simultaneously holding down buttons A, B, X, Y, and Start will exit KEGS and return to the Dreamcast Main Menu.
By default opening the disc door will exit KEGS and return to the Dreamcast Main Menu. This behavior can be changed in the Configuration menu.
KEGS will look for the first memory card (slot A1 to D1, then A2 to D2) with a saved configuration file. If it doesn't find its configuration file, it will look for a memory card (slot A1 to D1, then A2 to D2) to write to. The configuration file can be moved to a memory card in any slot. The configuration file usually requires 2 to 3 blocks.
After 10 minutes of inactivity, the screen will blank. Pressing a controller button or trigger, a keyboard key, or moving the mouse will stop the screensaver.
The Sega Dreamcast Keyboard works.
The Sega Dreamcast Mouse has not been tested, since I don't own one.

Sound quality degrades over time; it is sometimes related to Code Yellows and Code REDs.
Because the Dreamcast does not support double precision numbers, after 36 minutes the emulator starts skipping video frames and will eventually crash. I'm looking at possible fixes.
