You can be nostalgic about something for a lot longer than that thing was current. So it is with the Commodore 64, the Speccy and early computers in general.
I had a rubber keyed Spectrum 48K for a couple of years followed by a C64 that I used every day for another 4 years or so and here we are in 2019 and I’m reading about those ancient computers. I’m not the only one. There are vibrant communities around both computers and it’s great to see!
Somehow I can’t see myself feeling the same way about Windows 3.1, but I have to admit I have maybe not so fond memories of tuning autoexec.bat to get a few KB more memory in the DOS days…
What are the books I’m reading and where can I get them?
Backblaze and Time Machine causing the rainbow spinner.
My filesystem needed first aid. I think I can trace this back to the latest macOS update. I swear that half the updates cause filesystem corruption of some sort, but it also feels like I’m running First Aid at least once a month anyway!
Unfortunately for me, the error this time was:
error: btn: invalid btn_btree.bt_key_count
Apparently Diskutil can’t fix that error. The only thing you can do is erase the drive, reinstall MacOS and then restore your data. I was dreading it.
I have a Time Machine backup but I decided to make another backup of my home directory, while logged into another account. Lucky I did as an IO error showed up in Library/Caches/ – thankfully I think in an Apple app I don’t use.
I expected the business of restoring everything to be awful, but in the end the MacOS installer fired up Migration Assistant which let me restore my last Time Machine backup.
With that done it was time to install Brew again. The first package to go back in was coreutils but “brew reinstall” has a bug where it won’t accept parameters. I should have used “install” but “reinstall” with “–with-default-names” doesn’t work. Also coreutils and related packages are “keg-only” now so no symlinks to /usr/local/bin are made. You have to run “brew link” to link all the commands. It was a simple job then to rename each file, removing the “g” prefix.
I’ll find more things as I go that aren’t configured I’m sure, but thankfully restoring from Time Machine made the job much easier!
If you had a Commodore 64 in your youth, or you’re simply curious about the games produced for the system then Gamebase64 is for you.
Gamebase64 is an effort to catalogue every single Commodore 64 game, along with associated media like music, tape or disk covers, adverts and magazine reviews
It’s huge! The latest version is V15 and was released in 2016 holding 25,700 games. The games themselves don’t take up too much data but the artwork, music, and associated material really take up a lot of room. The whole collection is available as 3 ISO files and an artwork zip file. You can find download links to all of those in this thread, but if you don’t want to download them you can browse the collection here (or here) too. You’ll need to download the GameBase frontend to view everything as well as the V15 database files. I use Vice to emulate the Commodore 64.
GameBase itself is a database frontend for Windows that supports multiple databases. Many systems from the Commodore Vic20 to the Amiga or the Speccy and Amstrad CPC range are covered. You can find links to them on the GameBase website as well as many other databases.
I mainly use a Mac so I use Gamebase64 Browser. It’s a very slick frontend but if you search around you’ll find frontends written in a variety of languages for various modern platforms.
Installation was as simple as copying everything out of the ISO files into a directory, installing GameBase64 Browser in the usual way and when first run, pointing it at the directory where I had copied everything else.
Single disk and tape games work perfectly fine but I’ve had trouble with multi-disk games. To play Retrograde I had to manually unzip both disks into a temporary directory and load them in Vice outside of GameBase64 Browser. Not difficult at all but worth remembering when your favourite game asks you to insert disk 2. 🙂
If you’re at all interested in retro computers then GameBase is definitely worth checking out!
Ah Retrograde, a Commodore 64 game released by Thalamus in 1989. The Rowland Brothers, of Creatures, Creatures 2 and Mayhem in Monsterland fame created this game and it shows. Presentation is top notch. Some would say that this is a repetitive shoot ’em up but I love it. Nice mix of flying around shooting aliens and then a bit of a break with the underground bits. I love the graphics and the sound is a delight.
The gameplay is very simplistic, especially underground but the flying weapons are super! Just make sure you have an autofire on your controller. My thumb was sore from two levels when I remember Vice can do the hard work for me. I’m also glad Vice can save a snapshot of the computer state to save my progress as this game takes some time to complete.
Tim and Naomi of the Irish Passport Podcast visited Northern Ireland in July to experience the marching season in all it’s “glory” for their latest episode.
It’s a great episode, showing the stark contrast between the neighbourly and friendly people they met during the day on the 11th, and the hate fuelled crowd who descended on the area that night for the bonfire.
I visited Northern Ireland in the summer and really enjoyed myself there. The people we met were friendly and welcoming but it was well past the marching season. Hopefully I’ll write a post about that sometime.
Sometimes you accidentally dive down a rabbit hole of your own making. I came across the Retro Computer Scene search engine a few days ago and accidentally clicked on a link to a Commodore 64 disk image. Those files are small at 175KB so I decided to keep it and look at it later.
This morning I did and found Noice Driver v3.0a, a music disk for the Commodore 64 released in 1993. There are some great tunes on there but the name JEDININJA leapt out at me. It’s a good tune too!
The filename of the disk image is sb130978-1fbef9.d64 so I guessed it might have something to do with Scene Base. I downloaded their metadata list and found it there in the c64disk set!
Since MacOS High Sierra has been out for a long time this is probably old news to the tiny minority using coreutils. When you upgrade you might find that “df” and other commands don’t work properly.
Every time I opened a terminal after upgrading I saw errors saying commands had been aborted. When I ran “df” it would abort immediately.
I thought the upgrade had damaged my filesystem, especially since it introduced APFS. I ran “First Aid” in Disk Utility several times, both live and in recovery.
It then occurred to me to try the MacOS df in /bin/. It worked!
Coreutils is the package that includes lots of command line tools like “df”. I installed it using brew so the following fixed the problem:
brew reinstall coreutils
I noticed it put everything in /usr/local where my original commands were in /opt/ so changing the PATH in my .zshrc was necessary too. Everything was back to normal again! 🙂
EDIT: Some other commands were messed up. “find” had changed, but then I realised it probably isn’t in coreutils and I was using the MacOS version. This page led me to the right package names and the following command line:
The “–with-default-names” parameter restores the original filenames, removing the “g” prefix. Everything outside of the coreutils went in /usr/local/bin/ which I made sure was added to the path too.
