Modding Assignment
Progress Report

2. Fabrizio, Marc and Sarah
decided on the Prince of
Persia 1989 game.
While working on the
background,
complications arose and
the game chosen was
modified slightly.
No longer would it be
the 1989 version with
the blonde prince, but
the version for the Mac
with the prince wearing
the red outfit and the
blue turban.

5. Sourcing the Sound
(Sarah)

6. Sounds
(Sarah)
• Used to find a Prince of Persia walkthrough and
obtain the sound from that using to download it.
• I then tried to use to strip the video and cut up the
audio and export it as single audio files. Wasted an hour
expecting too much. Gave up.
• Moved onto . Had naming convention issues.
Resolved them via FLV to MP3 converter I found online.
With this I converted a FLV into an MP3 and exported
from back into .
• From here I cut out each sound needed and exported
them as singular sound files.

What Marc
made

8. How He Did It
• Using Photoshop, Marc rendered all of the
2.5D perspective imagery into 2D by:
– Painstakingly modifying the edges of the walls,
floors, tiles, roof etc
– Modifying the non-prince sprites that Sarah made
so that they could be implemented as solid
objects within the room on Game Maker
– Removing a lot of the room for the vertical slice
– Marc rendered all of the Prince Sprite sheets into
working animations.

9. Fabrizio the Game Maker
• Fabrizio implemented the game play through
Game Maker.
• Fabrizio went through six working drafts
before he finally found one that implemented
the Prince’s movements without bugging.
