JAWTC64 Help

JAWTC64 is a Java-based emulator that runs on PCs supporting JRE/JDK 1.4.

Loading programs

You can load a program using the 'Attach image' menu item. This command first attaches a C64 image to the emulator.
Afterwards you can select to load a program from the image using the 'Load program' or the 'Fast-Load program' menu item.
In most cases you should try the latter loading method first, as it loads way faster than the slower 'Load program' method. But some programs won't load correctly using fast-load, in which cases you should resort to normal (slow) loading.

The following file extensions are currently supported when loading programs: .d64, .t64, .prg and .p00. Additionally, if you saved a modified image before, you may load the .gzd file which stores the modifications to the corresponding original file. In that case the original .d64 image is loaded first and then the modifications are applied.

Starting a program

The 'Run current program' menu entry is used to run a program that was previously loaded. The command simply types „RUN“ on the command prompt.

Keyboard input

Keyboard input can generally be done using the normal PC keyboard. Additionally some special C64 keys (e.g. the "Run" key) can be accessed using the 'Enter a special C64 key' menu item. Also normal keyboard input can be done via the 'Type text' menu entry, although this is normally not necessary if a keyboard is available. Via the 'Type text' menu item you also get a history of the last commands which were entered. This lets you easily repeat one of those commands by simply selecting it from a listbox.

Some C64 keys and how to input them on a PC keyboard:
C64 keyPC key
Arrow leftEscape
RunCtrl-R
BreakCtrl-C
The cursor keys are used for joystick navigation, the F12 key or the left mouse button are used to simulate the joystick button. To toggle the joystick between the C64's joystick ports 1 and 2, use the 'Joystick' menu.

Miscellaneous stuff

You may restart the emulator by using the 'Reset C64' menu item.
The 'Size' menu can be used to increase the size of the emulator window. Please note that this scaling may consume a lot of CPU time when used with a JDK/JRE up to version 1.5. JDK/JRE 1.6 implements a faster scaling and is therefore recommended when using this option.

Enjoy the emulator!
