Fourth try is a charm. For a while now I’ve been trying to learn how to make cheap and quick copper tape circuits as described briefly in Bunnie’s 2018 Toorcamp Keynote talk where he discusses the elements for electronics development that has so far provided him with much success. Toorcamp in 2018 happened to provide me with the copper tape used in this circuit, so I thought I’d give a shout out to my Neg9 crew and those who shared the weekend with me.Read more »
NME made a good list of 1970s songs. Since I didn’t experience the 1970s myself, I can’t tell you how accurate this list is. I know that it’s subjective, but it was really fun to convert to a Youtube playlist and listen to. How did I do this? Well, see the bottom for some simple source code.Read more »

I’ve been working on OPL2 code for a while now. I’ve started to understand at a level beyond what I could a few years ago. This is progress. What does it mean? Let’s discuss problem-solving in the context of OPL2 in 2020. I want to write a piece of software for the Intel X86 architecture. I want it to be below the kernel of the computer meaning that there is no operating system, no bootloader and if you’re really wild, only a single function needed from the BIOS. I wrote all this and there are bugs, but instead of focusing on those bugs, we’re instead going to look at just OPL2.
If I were to get this code working on a host machine, our process of problem-solving would actually be a lot easier. Write more code and fix anything that comes up. Because testing on a host is one step more difficult than testing on a VM, I decided that most people would choose to use a VM instead of running my game on their host or a random piece of ancient hardware they have in storage. It is true of me, but I have an excuse. There is a debugger for my VM, Qemu but there is not one in my game’s kernel. That comes in mighty handy when things go wrong.Read more »
