King's Quest IV: The Perils of Rosella AGI Help
King's Quest IV: The Perils of Rosella's original requirements:
Audio Problems
Problem - Music only comes over PC Speaker:
You get the one MIDI voice beeping through the case speaker. This is not a bug, this is the way the games
were made. They did this when these games were new.
Solution 1:
Play the game in DOSBox. If you change dosbox.conf
to set "machine=tandy" instead of "machine=vga" there will be 3 voice PCjr/Tandy music
with a white noise channel. You can also get Tandy sound in Sierra's AGI games without having to emulate Tandy
video mode if you run "sierra.com" with a "-t" after it in the game's directory, i.e.:
sierra.com -t
Solution 2:
Use a patch by Anders Olsson, agi-mid05.zip
(12 kb). You will hear all three MIDI voices through your sound card. (2K and XP users will also have to run
the games with
VDMSound to hear it.)
Solution 3 (preferred):
Run the games with one of the new third party AGI interpreters such as NAGI
or Sarien. With NAGI you'll hear all three MIDI
voices and even have limited mouse support within your AGI games.
Graphics Bugs
Problem - Garbled Text:
Some of the newer graphics cards might garble the text in these games and make it unreadable. This problem
will occur on Windows 95/98/ME as well.
Solution #1 (preferred):
Unzip this modified
Sarien interpreter into the game's folder and run "King's Quest IV.exe" to play the game.
Solution #2:
Run the games with a third party DOS emulator like DOSBox
or one of the new third party AGI interpreters such as NAGI
or Sarien. With NAGI you'll hear all three MIDI
voices and even have limited mouse support within your AGI games.
Game Specific Bugs
There are a couple of bugs the game has that are not speed dependent.
Problem - KQ4 AGI Copy Protection:
When the game starts
Solution #1:
When the game asks you for a word from the manual, press "Alt+D" and a screen will pop up with the
version info. Press enter and at the prompt, type "MARBLE". The game will then start.
Problem - Can't Climb the Whale's Tongue:
The Whale's Tongue scene in King's Quest IV: The Perils of Rosella seems impossible to solve.
