Sierra Patch patches the following games to allow them to run. Fixes the timing error. From the Readme:

A patch for the following Macintosh Sierra On-Line Games:
-Leisure Suit Larry I & V
-Space Quest I & IV
-King's Quest V & VI
-Freddy Pharkas
-The Castle of Doctor Brain

This patch fixes a problem that caused the games to lock-up because of problems with the date. Supposedly after September 18th, 1993 many games stopped working properly.

I do not get these games to work on my Q700. It's nearly the same machine as a LC475.
Can you tell me, how do you get these classic sierra-games to work on your setup?

I think it's perhaps the 24Bit adressing and the gfx chip.

I do not use the patch. I change the date before 1993. Sierra's adventure games run great on my Macintosh LC475. But on my Performa 6116 some times an error appears and i have to reset the computer. Maybe because of the powerpc processor.

This no longer works unless I turn back the clock to 2009 or before. My guess is that this patch merely shifts the problematic date forward and now this new date has also expired. Maybe someone can reverse engineer what this patcher does and then write a new improved one that dynamically updates the game to work at least for the next 5 years, if possible.

It's a weird bug anyhow. Seems like an overly frugal programmer used too small a data type for a timer. This would have been excusable if it hadn't limited the lifetime of KQ5 to a mere 2 years…

i don't know why but the sierra patch doesn't work. I patch the games that this programm support but does nothing. The only way to play the games is to change the date of the mac os (i put a date before 1993). But again i have some problems. For instance the 'restore' does not work on King's Quest 6 when i try to open a saved game.
