Suchyles has found two data cards already, but in a Gathering mission there are bound to be more.

Suchyles has found two data cards already, but in a Gathering mission there are bound to be more.

For a Gathering mission you need to stick around a bit longer and find as many data cards as you can. You're scored on the number found and time taken, so you must decide when to stop looking. cyningstan.itch.io/star-cadre-c... #starcadre #ibmpc #msdos #cga

A screenshot from the MS-DOS version of Barbarians, showing off the palette. The thick forest shows the various autumnal shades this palette is capable of through dithering: purples, oranges, browns, and various shades of green.

My #ibmpc #gamedev projects use C. The graphics were based on the version for the Psion Revo, but the 4-greyscale monochrome graphics were recoloured in the most colourful or gaudy of #cga palettes. cyningstan.itch.io/barbarians-dos

Aren the Ranger buys a couple of poultices at the ranger supply shop. These can be used with a skill of Medicine:1, but at that skill level, many will be wasted in unsuccessful attempts to heal. At Medicine:2 skill there's nearly a 50% chance of success, so they become more worth buying. The Poultice is enlarged in the inset.

A preparation of herbs for healing wounds, a Poultice can be applied to wounds to heal them at the rate of 1 hit point per turn. The poultice will often fully heal the character. Get The #ChambersBeneath from cyningstan.itch.io/the-chambers... #roguelike #ibmpc #msdos #cga

In the third level of Double Trouble, Multibot has just shot a forcefield generator, disabling forcefields that extended from it to the north and south. Meanwhile, Strider navigates a corridor full of crates to reach its data card at the top.

In the third level of Double Trouble, Multibot has just shot a forcefield generator, disabling forcefields that extended from it to the north and south. Meanwhile, Strider navigates a corridor full of crates to reach its data card at the top.

Double Trouble level 3 builds on the same theme as level 2. The robot in the bottom half needs to shoot the generator that powers forcefields blocking both robots' paths. Get the game and the level pack from cyningstan.itch.io/team-droid #TeamDroid #ibmpc #msdos #cga

A Battleship, escorted by Cruisers and Destroyers.

A Battleship, escorted by Cruisers and Destroyers.

Battleships are the largest ships afloat. They have more power and a longer range than cruisers, and are the best units to have in a sea battle. They are also good for offshore bombardment. cyningstan.itch.io/waterworld. #ibmpc #msdos #cga #BarrenPlanet #Waterworld

This amulet on level 8 works well for intelligent characters, warding off blows from the monsters. It is enlarged in the inset.

The magic amulet appears in the mid levels of the #Ossuary. Its magical protection adds +2 to intelligence, and makes intelligence the stat for defence. This and the wand work well together. Download the game from cyningstan.itch.io/ossuary #ibmpc #msdos #cga #zxspectrum

Looking for the data card in a Retrieval mission. Predictably, it's not conveniently stored in a cabinet right by the entrance, so the search continues.

In a Retrieval mission you have to find the very important macguffin and get out with it in your possession. It may be in a cabinet or it might be carried by an enemy. cyningstan.itch.io/star-cadre-c... #starcadre #ibmpc #msdos #cga

But in early 2025 I picked up my old #cga roguelike #gamedev project for #msdos The Chambers Beneath again. That was released in July 2025, and shortly afterwards, the #DOSember game jam was announced. I thought #Barbarians would make a good entry. cyningstan.itch.io/barbarians-dos

Meleel the Ranger picked up a potion down in the dungeon. We won't know what this potion really is till Meleel either drinks it, throws it at a monster, or takes it to the Mage's shop for identification.

Look at this *gorgeous* little Psion Series 3 handheld computer from 1991! Hinges and screen are perfect, but I like to reinforce the hinges with 3M tape, as this is a key point of vulnerability. 😍

The second level of Double Trouble. At the top, Soldier has jumped over the forcefield with the aid of a spring that's still in its inventory. Meanwhile at the bottom, Multibot has also jumped its forcefield and is preparing to push its data card all the way to the reader.

Level 2 of Double Trouble needs a different kind of cooperation. Neither robot meets nor passes objects to the other, but one robot needs to shoot the forcefield that powers the generator the blocks the other's movement. cyningstan.itch.io/team-droid #TeamDroid #ibmpc #msdos #cga

Cruisers are the more powerful units in this battle.

Cruisers are the more powerful units in this battle.

Cruisers are medium-sized combat ships with a good attack range. They're useful to add extra power to naval battles, and to bombard ports and other land units from off shore. They're slightly slower than destroyers. cyningstan.itch.io/waterworld. #ibmpc #msdos #cga #BarrenPlanet #Waterworld

Looks like having two instances of copy trying to copy the same file to the same place confused it. Hopefully the remaining instance should complete successfully. May be worth checking the size of the destination file from time to time to see if/how it's progressing.

Rescue missions are subtly different. With multiple hostages to find, some of whom have useful skills, you can recruit the hostages themselves to help. You also score per hostage freed. cyningstan.itch.io/star-cadre-c... #starcadre #ibmpc #msdos #cga

By 2024 I decided the time was right for an #msdos version of #Barbarians. I'd already ported my third ZX Spectrum game Ossuary. I decided to start work on an MS-DOS port before the idea gets eclipsed by a more complex game on the same subject. cyningstan.itch.io/barbarians-dos

The Barbarians victory screen on the ZX Spectrum. The map display fits nicely into the ZX Spectrum's attribute grid, allowing quite a colourful display. Only two of the machine's 15 colours remain unused in the game, the two blue shades. Even magenta is used, for the cursor not shown here.

The #ZXSpectrum had such affection among its former owners that it maintain its popularity to the present day. So in 2012 when I released #Barbarians for the Spectrum, the game attracted much more attention than the original Psion version ever did. cyningstan.itch.io/barbarians #gamedev

And, my precious children, it delivered. And the ZX81 birthed the Spectrum; the Spectrum laid the ground for the Psion 3 and 5mx.

And then the Single Pane of Glass extremists stole that future from us.

A screenshot of the Psion Series 3a emulator for MS-DOS, running under DOSBox. Dragonfell has been installed, its icon showing at the top left of the emulated Psion's display. The resolution of the Series 3a is 480x160; most of the 640x480 DOS screen is therefore blank. Although Dragonfell is designed for the original Series 3 with its 240x80 resolution, the Psion Series 3a runs it fine, scaling up the graphics to fit the Psion Series 3a's bigger screen.
