It works now, thanks!

You need to update your OS/FW first: In the XFCE menu, click "System"->"Upgrade Pandora OS", wait until the update finished (needs an internet connection, of course), then reboot your Pandora. (note) apparently the PND system ignores the tag in this .pnd

I'm on Super Zaxxon 1.55 with default kernel. I tried also booting kernel with DSP RAM, but unfortunately my SD card is ext4 formatted, and old kernel doesn't support it, so upon booting I couldn't run any PNDs. Is booting with kernel RAM needed? If needed it would be nice adding it to description.

Doesn't work for me, it looks like it's missing a library (or I'm doing anything wrong). Each time I try to run it, I only get: "error while loading shared libraries: libc64.so.1: cannot open shared object file: No such file or directory"

The 1.0.0.2 update adds some missing DSP files (logbuf, some c64_tc testcases did not run b/c of that) and adds a lot of new (non-visual) testcases. Open the "c64_tools testcase shell", then run ./c64_tc to see the complete list of testcases. @usr_share: guess that's my sick sense of humour then ;)
