Welcome!
JZX is a Sinclair ZX Spectrum emulator written in 100% Java. It is the third emulator I have worked on, the previous two being XZX (a UN*X emulator) and WinXZX (the Win32 port of XZX.)
While I am the primary author of JZX, I did use the source of the two emulators above as inspiration or I manually translated pieces of it from C to Java. Due credit is given to the original authors where appropriate; see bottom of this page for the appropriate copyright notices. I also made use of the excellent technical documentation at The World of ZX Spectrum.
You can run the emulator as an Applet on the main JZX page.
You can download the run the emulator as a standalone Java program:
- Save jzx.jar on your hard drive.
- Launch the emulator with the following command:
- Sun JDK: java -jar jzx.jar [parameters]
- Sun JDK: java -cp jzx.jar org.razvan.jzx.JZXFrame [parameters]
- The command line [parameters] you can specify are as follows:
- -scale x: Scale the window size by 'x', where 'x' can be 1, 2 or 3.
- -mode m: Start the emulator in 48k ('m' = 48) or 128k ('m' = 128) mode.
- -snapshot s: Load a given .Z80 snapshot file into the emulator.
I have tested the standalone emulator on a Windows XP Professional computer, running Sun's JDK 1.5.0. I have tested the emulator on the same machine, using Firefox 1.5. If you encounter any bugs or any .Z80 snapshots that do not execute correctly in the emulator, please contact me.
If you're a Java programmer, you may be curious to read the Javadoc or take a look at the source. Here is an article I wrote about this emulator in the Java Developer's Journal (July, 2002.)
