<ul id="usage">
<li><span class="label">Usage/Hints</span>
<ul>
<li>If something does crash or freeze
<ul>
<li>Try another Amiga-model. A500+ for OCS/ECS and A1200 for AGA does work best.</li>
<li>Use the right rom. Selecting a wrong rom may freeze the emulation. If possible, use original kickstart-roms.</li>
<li>If you are using original A3000/4000 kickstart-roms, make sure to enable "32bit address-space" in the CPU-page.</li>
<li>If you are using the AROS kickstart-replacement, you should also give some fast-ram.</li>
<li>Try to enable "Compatible" in the CPU-page.</li>
<li>Try another memory setting or give more memory.</li>
<li>Try to set the floppy-speed back to 1x. Some stuff does not load if "Turbo" is selected.</li>
</ul>
</li>
<li>If hardfiles did not get recognized
<ul>
<li>Select an A600/A1200 at the "Defaults"-page.</li>
<li>Or, go to "Chipset/Features/Manual" and select "Onboard-IDE" or "PCMCIA-slot" manually.</li>
</ul>
</li>
<li>If gamepads/joysticks did not get recognized
<ul>
<li>Try to press buttons on the controller.</li>
<li>Open a new tab and return to the SAE-tab. (Chrome)</li>
</ul>
</li>
</ul>
</li>
</ul>
<ul id="api">
<li><span class="label">API</span>
<ul>
<li>There's no written documentation about the API yet, blame me. At least there's a commented example:</li>
<li><a href="example.htm">example 1</a></li>
<li><a href="example2.htm">example 2</a></li>
</ul>
</li>
</ul>
<ul id="safety">
<li><span class="label">Safety</span>
<ul>
<li>Whatever you do, you can't harm your computer or change local-files.</li>
<li>Everything is running enclosed in the memory of the browser.</li>
<li>Changes to floppy-/hardfile-images are not stored physically, but to memory only.<br />
Reloading the window/tab (e.g. press F5) does reset all altered floppy-/hardfile-images and configurations.</li>
<li>No Amiga-virus (on floppy-/hardfile-images) can infect your real computer or device.<br />
If you close the window/tab of SAE, all possible viruses will die peacefully.</li>

<ul>
<li>Common
<ul>
<li>Chaned the project-name from 'Janus' to 'SAE' (Scripted Amiga Emulator).<br />
This step is necessary because i did'nt enough research before the initial release.<br />
There is already a project with that name in it. (<a target="_blank" href="https://janus-uae.sourceforge.net">janus-uae</a>)
I'm sorry for that, that was kinda stupid :)</li>
<li>Separated the GUI form the core and rewrote most of it.</li>
<li>Simplified the whole code. This means, that functions are called faster.</li>
<li>Ported new Copper-, Blitter-, Audio-, Disk- and event-handling code from WinUAE 2.5.0</li>
<li>Moved all "beam-functions" to events.js, for faster access.</li>
<li>Added "CPU-usage" to the GUI.</li>
<li>Added "Hall of Fame".</li>
</ul>
</li>
<li>CPU
<ul>
<li>Added support for exact cycling. The CPU have now 7.09 MHz on PAL and 7.16 MHz on NTSC resp.</li>
<li>Added option for "Original"- and "Maximum"-speed.</li>
</ul>
</li>
<li>Audio
<ul>
<li>Added a ring-buffer before output. No more "bagpipe"-like audio.</li>

e.g. "Agony" was not starting, if audio was disabled.</li>
</ul>
</li>
<li>Display
<ul>
<li>Switched from the RGB to the 565 texture-format-encoding in WebGL, which gives a little more speed.</li>
<li>Added support and a option for 4x scaling.</li>
<li>Fixed screen-draging in lo-/hires-modes.</li>
