<h3>JaC64 Test page</h3>
Thanks for trying JaC64, a 100% Java C64 emulator. You can find more
information about JaC64 at
<a href=http://www.jac64.com/>jac64.com</a>, and (old site)
<a href=http://www.dreamfabric.com/c64/>dreamfabric</a>.
If everything is working, you should see a running JaC64 below
(and some instructions). <p>

<h4>JaC64 Features and Known Bugs</h4>
<b>Feature:</b>
<ul>
<li>CPU 6510, most of the 6510/02 instructions (inluding many undocumented)
<li>RAM/ROM and Bank Switching (ROM - on / off, IO on / off)
<li>Interrupts (IRQ, NMI) from raster, sprites, CIA timers, etc.
<li>VIC Graphics (text modes, hi-res, multicolor) - instruction/cycle
based, sprites (normal, expanded, multicolor, collisions)
<li>SID (6581) Sound, with support for most of the SID features such as
3-oscillators/4 waveforms + mix, ADSR, synch., ring-mod, filters, etc.
<li>CIA - timers
<li>Keyboard & Joystick
<li>Support for .d64 .prg/p00 and .t64 files (directly into memory)
<li>Support for 1541 - e.g. loading .d64 files from an emulated
diskdrive
<li>New fullscreen mode activated/deactivated by pressing control-f12
</ul>
<b>Known Bugs:</b>
<ul>
<li> VIC-II emulation is not yet 100% correct (see the demos/music here)
<li> Some instruction are also not 100% correct (and/or interrupts handling)
<li> SID is not 100% cycle correct
</ul>
<h4>Requirements to run the applet</h4>
A JRE (1.4 or better) is required, and you need to have a folder
called "roms" with the rom files for the C64 for the applet to work.
From version 1.0 Beta 3 this folder is no longer needed since the rom
files are included in the jar file.
<h4>Controlling the C64</h4>
Joystick emulation:
<ul>
<li>Up: Numpad 8 or arrow up
<li>Down: Numpad 5,2 or arrow down
<li>Left: Numpad 4 or arrow left
<li>Right: Numpad 6 or arrow right
<li>Fire: Numpad 0 or shift
</ul>
Other important keys
<ul>
<li>ctrl-alt-backspace: resets the emulator
<li>ctrl-f12: toggle fullscreen mode
<li>ESC: run-stop
</ul>
<h4>Parameters to the applet</h4>
<table>
<tr><th>Parameter</th><th>Usage</th></tr>
<tr><td>autostartDisk = URL/File</td><td>The disk/tape image to load file from</td></tr>
<tr><td>autostartPGM = Filename</td><td>The file from the disk/tape image</td></tr>
<tr><td>autostartProgram = file number</td><td>The file number (id) of the program in the games.txt file</td></tr>
<tr><td>soundOn = 0/1</td><td>The status of sound (0 mutes applet)</td></tr>
<tr><td>doubleScreen = 0/1</td><td>if set to 1 the emulator will be running
in double size mode</td></tr>
</table>
