Usage notes

System ROM

You can supply other A800 OS ROM as Atari800/boot.rom. Alternative Basic ROM can be placed to Atari800/boot1.rom.

Integrated 800XL ROM includes SIO turbo patch (fast disk loading).

Turbo ROM has hot keys to control the turbo mode:

• SHIFT+CONTROL+N Disable highspeed SIO (normal speed)
• SHIFT+CONTROL+H Enable highspeed SIO

Additionally, you can control the speed of turbo loading in OSD menu.

Disks

A800: After mounting the disk, press F10 to boot. Some games don't like the Basic ROM. Keep F8(Option) pressed while pressing F10 to skip the Basic.

Differences from original version

• Joystick/Paddle mode switched by joystick. Press Paddle1/2 to switch to paddle mode (analog X/Y). Press Fire to switch to joystick mode (digital X/Y).
• Use ` key as a Brake on reduced keyboards.
• Cursor keys are mapped to Atari cursor keys.
• PAL/NTSC mode switch in settings menu (A800)
• Video aspect ratio switch in settings menu
• Some optimizations and tweaks in file selector and settings menu navigation.
• Standard OSD menu for cartridge/disk selection.
• Mouse emulates analog joystick(Atari 5200) and paddles(Atari 800).
• Fire 2 and Fire 3 on joystick.

Disable Basic ROM by Joystick.

Fire 2 on joystick acts as an OPTION key while reboot. It's valid only 2 seconds after reboot. After that Fire 2 doesn't affect the OPTION key.
