I won't go into the details of what was involved in patching the game, but I'll offer a few suggestions for playing.
Save your game often. If you want to reload part one, enter LOAD and then NEW GAME 1. To reload part 2, enter LOAD and then NEW GAME 2. The beginner game can be reloaded with LOAD and then NEW BASIC.
There are a couple walkthroughs available on the internet. One of which suggests SAY TO SAM "GO NORTH AND KILL A BLACK RIDER."

You don't have to say SAY TO PIPPIN "GIVE MATCHBOX TO ME or SAY TO TOM "HELP. You can shorten this to PIPPIN "GIVE MATCHBOX and TOM "HELP.
You don't have to say KNOCK ON WHITE DOOR. Simply KNOCK.
I played all the way through part 1, and the beginner game. I haven't played part 2, other than to start it and check that I could load a finished game from part 1.
Is this a good game? It has good points and bad points. Certainly, speeding it up got rid of a major problem.
