1 1  The Elona Porting Project aims to create an extensible and maintainable port of the roguelike [[Elona]].

3 -The project aims to make an initial port of Elona to Java (pure, no native code outside of the Java platform) through the HSPlet framework that will be nearly 100% compatible with mainline Elona. Within reasonable bounds, the port should behave just like mainline Elona. Some aspects are difficult or impossible within these restraints (for example, inter-process mutexes do not exist in pure Java; therefore, prohibiting multiple active instances through inter-process mutexes would not be possible); such aspects should be minimized if possible.

11 +HSP compiles files into its own object code format, commonly called "packfiles." These files contain byte code that interpreted at runtime by the HSP runtime virtual machine. start.ax is the entry point for most HSP programs, including Elona.

13 +HSPlet is an implementation of the HSP runtime environment in Java through a compiler and HSPlet runtime library. HSPlet compiles HSP's packfiles into one or more Java .class files.
