Grand Theft Auto: Liberty City Stories is a massive game to cram onto the system. How did you get all the audio, textures and scripting onto the 1.8GB UMD?
GH: Lots of hard work and attention to detail. Every asset in the game had to be trimmed to the bare essentials. The team at Rockstar North has been involved every step of the way and they had some very clever compression techniques they'd used in Vice city and San Andreas that the team here heavily optimized for PSP in order to get all the various assets onto the disc. Without the code there would have been no way for us to get 10 full radio stations in the game with everything else.
Data streaming has long been a technique used in the Grand Theft Auto series. Were there any changes made to decrease reliance on streaming in Liberty City Stories?
GH: There were some fundamental changes to the way streaming is accomplished to minimise the reliance on the disk. With the help of Rockstar North, we painstakingly organized data on the disk such that the game can pull off information in chunks. The actual streams are pulled in bursts, allowing us to only spin up the disc occasionally.
