6502 Test Programs

Recursively unpack zip files in their respective directories:

find . -name "*.zip" | while read filename; do unzip -o -qq -d "`dirname "$filename"`" "$filename"; done;

Clean up the zip files:

find . -name "*.zip" | while read filename; do rm "$filename"; done;

I have downloaded the complete ftp.scs-trc.net and c64.rulez.org archives and I wanted to copy the unpacked archives onto an SD card for my Chameleon 64. These commands helped me a great deal to unpack and remove all of the zip files.

I don’t know about you, but when reading codebase64.org, the high-contrasted text makes my eyes hurt. So I created a very short CSS that overrides the original and makes it much easier to read the website without getting a headache.

I’m not into web-design at all, so sorry if you see something blatantly stupid here, but the following style sheet works all right with Firefox’s Stylish plugin for me:

@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain("codebase64.org") {

div.dokuwiki h1 a, div.dokuwiki h2 a, div.dokuwiki h3 a, div.dokuwiki h4 a
{
    color:#090 !important;
}

body
{
    font-family:Verdana !important;
    background-color:#232 !important;
    color:#8a8 !important;
    font-size:100% !important;
    text-shadow: 1px 1px 1px #222;
}

.li {color:#ccc !important;}
div.dokuwiki .li {color:#792 !important;}

Sometimes you might want to put some effects onto the audio signal that comes out of your Mac. If you listen to music via iTunes, you can play around with the EQ settings, but that’s not too much. What if you want some more sophisticated sound processing capabilities at your hands, or you want to put effects on the sound of other applications, like web browsers? We have tons of great (free) VST/AU plugins around, why not running our system sound through them? This short guide is trying to show you how to do that for free.

So what kind of software do we need? First we need our VST/AU effects. You can either grab your favorite ones lying around, or you can use Apple’s built-in Audio Units as well. To look for great effects, I can recommend to check out kvraudio.com, they have a huge database of effects.

Second, you need a host app for the VST/AU plugins. What I was looking for is a lightweight, free app that won’t take up too much system resource. A full DAW would be overkill for our needs. Luckily, Apple has an answer for this problem, and even for free! With the (free) Xcode development environment comes a software called AU Lab, that does pretty much what we want: it acts as an Audio Unit host and processes real-time audio signals with them.

But how do we root the system sound through it? For that we need Soundflower, which is also free software.

Let’s make all this work together! Install Soundflower, open Sound Preferences, go to the Output tab and select the 2-channel Soundflower entry. Now start AU Lab and create a new document, and select Soundflower as input source, and set the output to your preferred sound card output (eg.: Built-in output). When ready, you’ll see two stripes, one for audio input and one for audio output. On the input side there will be a part call Effects. There you can stack up your effect plugins. Go, select an effect and edit its parameters. I usually put a slight reverb onto the audio signal to give some spacial feeling to the sound when using my headphones, but you can choose any other one for your own needs.

Basically, that’s all there is to it! You should hear the difference on any audio getting played back on your Mac. Good luck for the set-up, cheers!
