Pretty amazing what people can do; for example, Demon from the GTAPortable forums was able to whip up this little program were you can create a 3D model object for GTA.
Something I never thought will happen with Liberty City Stories is the fan made software
that now starts to pop up. As most of you know by now Edison Carter’s
Cheat Device enables us to do a lot more in Liberty City Stories. It
later then had the ability to create your own custom cheats. The LCS
CheatSync then came along that allows you to choose several cheats,
made by fans, from a large database. Now someone created the LCS Object Creator.
It
basicly does what its name says. You can create an object, or rather 3d
model, that’s already found in the games code. This allows you to build
your own maps, like stunt parks, new islands or anything possible with
the 3d models that’s found in Liberty City Stories. The latest version
is still a bit buggy, but future releases will include a map of Liberty
City that will make it easy to get the coordinates of the location you
want to place your objects. Examples of custom maps are for instance
the Wolf Side Hill or The Cruise Ship. When you created your objest(s),
you can save it to your cheats.txt file that must be uploaded in your PSPs root directory. You’ll need the latest Cheat Device from Edison Carter in order for this to work.
