Gmu 0.10.0 released!

2016-07-13 19:18
Here is a new release of the Gmu Music Player. Version 0.10.0 comes with a couple of new features and bugfixes. Also, lots of code has been changed/rewritten for better quality, security and performance. Since Gmu turns 10 this year (I released the first version of Gmu for the GP2X back in 2006), 0.10.0 seems like a suitable version number for this anniversary release.

Gmu setup dialog

Noteworthy new features and bugfixes:
  • A configuration dialog in the SDL frontend for configuring lots of Gmu settings previously configurable through the config file only is now included
  • Gmu now stores its configuration and playlist information in XDG compliant locations (typically ~/.config/gmu and ~/.local/share/gmu)
  • An Ogg Opus decoder plugin for decoding Opus audio files
  • A new module decoder plugin using the OpenMPT decoder library
  • An experimental media library feature (disabled by default; only usable from gmuc currently)
  • Optional fade-out on skip feature (fades out the current track when user explicitly chooses another track)
  • A few fixes for supporting musl libc based systems
  • More robust networking code in gmuc (faster detection of lost connection) and Gmu
  • Command line mode for gmuc utility for controlling Gmu through command line commands e.g. "gmuc play /path/to/file.ogg" or "gmuc pause"
  • Improved build system with a configure script for auto detecting features (not autotools based)
This is mostly a source release right now, but I have built a version for the Z2 as well. It has been built using mozzwald's OpenWRT toolchain, so it runs on OpenWRT with musl libc.

Gmu on the PocketCHIP handheld

2016-07-10 11:42
NeoTheFox has ported Gmu 0.9.1 to the PocketCHIP. The PocketCHIP is a handheld computer based on the C.H.I.P. single board computer. It is an ARM-based device primarily meant to play retro games. I haven't tried it myself yet, but it seems only minor changes were required to make Gmu run.

Schematic for the C64 power supply project

I have been asked for a schematic of my C64 power supply a couple of times. So here it is.

The correct value for the transformer's primary rating depends on your mains voltage, of course.

For a detailed description of my circuit, please have a look at the original article.

New Arch Linux image for the Zipit Z2

2014-01-25 12:11
With all the recent activity around the Z2, I thought it might be worth it to create an up to date Arch Linux image for the Z2. Although it is theoretically possible to update my old image, it is quite some pain to actually do so. So what I did is take an official system image for an ARMv5 plattform from the ArchLinuxARM website and modify it to work with the Z2.
