A new tactical combat game for #msdos has been released! #StarCadre Team Command puts you in charge of a squad of elite operatives in the far future, conducting special missions on behalf of an interstellar civilisation. Get it from cyningstan.itch.io/star-cadre-t... #ibmpc #cga
A collage of screenshots of Star Cadre: Team Command against a background image. The background images shows the K-53 modified fighter craft in the foreground, that takes the away team on their missions, on a landing pad beside its hangar, with planting around, a city scape behind, mountains in the far distance. The screenshots are all in 4-colour CGA. They include: the title screen which is a 4-colour version of the background image, a mission taking place in an industrial complex, and the personnel screen where a new recruit is being added to the team.

@edwinet.bsky.social "reminder to write/commission a piece on genAI translation in gamedev" I'd love it if it touched on resources avail for people who want to avoid machine translation. Only because SEO makes googling for anything a nightmare. Speaking as someone who wants to make fan translations.

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

Update: I was testing this on a Windows 98 VM and I noticed that the NoCD patch wasn't working. So I implemented it a different way and uploaded the new version. It should print out whether it's patched or not in the main menu now too.

Oh sure! I'd have to tidy up my notes. I wanted to do a proper write-up at some point but I also didn't want to delay the patch. :) It was a lot of stepping through the game with a debugger and winging it.

I'm thrilled to share news about an online #mediaarts exhibition I've curated with Helen Stuckey, "Revisiting Australian CD-ROM Art of the 1990s". With the support of @aarnet.edu.au and the #EAASI platform, it is now possible to access ten key Australian interactive artworks of the 1990s, online.

I translated "Backstage" (1993) presented by "LIVECLUB", a mail-order subscription service for CDs and VHS tapes. The in-game goal is to win a radio contest, but the game also invites you to enter a real-life competition that closed in 1994. archive.org/details/back...
On a dark purple digitized wall background: "LIVECLUB" logo in red letters; "Presents"; the logo for "Backstage", a graffiti-like design with green lettering outlined in yellow; "Freeware - freely copyable".Screenshot of "Backstage": Pixel art. The inside of a house in cross section, with two rooms fully visible - the living room on the top floor and the kitchen on the bottom floor - and other rooms leading off from them, partially seen at the edges. The hero character is walking down a staircase that connects the two floors.Screenshot of "Backstage": Pixel art. The hero character is standing at the entrance to a building with large open double doors, facing into it. The sign above says "LIVECLUB". There are promotional displays of what look like books or magazines.Screenshot of "Backstage": Pixel art. A cross section of a subway train carriage with darkness surrounding it, except for a light passing by overhead. There are several passengers standing or sitting on the train.

Saying it for maybe the 50th time: Do not accuse someone of using AI unless you have ABSOLUTELY AIRTIGHT proof, because if not, you're just adding to the paranoia and causing stress for hard-working artists. And yes, going onto social media and going 'Hrrm, I've no proof, but...' is an accusation.

8 years ago I made this NES game called Lizard. I never know how to describe it... a quiet game of exploration, with a little bit of difficulty, a little bit of mystery. It was a kind of game I wanted to see more of, and I still look at it fondly. rainwarrior.ca/lizard/

I did trust that if the game did force you to choose between oxygen and navigation, that it would be obvious what the limits were.
