47	52	[Bubble Escape][] is a video game written for the Commodore 64 where the player must guide a bubble through

56		SITU-MON is a machine language monitor for 6502-based systems, written (by hand!) during RetroChallenge 2015/07 and entered into an emulated Commodore 64 using SITU-PAN.
	61	SITU-PAN is a front-panel switches simulator for the Commodore 64. It displays 8 virtual LEDs and 8 virtual dip switches on the screen. The LEDs display the bit pattern at the current address in memory. Via the keyboard, the switches may be toggled, a new bit pattern written into memory, and the address advanced. In this way, machine code programs may be entered into memory, and then run. SITU-PAN was written during RetroChallenge 2015/07 for the purposes of entering SITU-MON into an emulated C64.
