The echo command is not needed on AmigaOS 2.x because the command is built into the Kickstart. However, you can copy the echo command from the Workbench 1.3 disk and put it in the 'c' directory on your disk. Now the game should boot on Kickstart 1.3.
For the joystick thing. Maybe there is tool on Aminet or something that you can put in the startup-sequence to remap the keyboard control?
