#C64 #Delphian progress: still working on this, been busy designing the galaxy economy systems, working out how the ship gets upgraded, and a few other bits. Ship now has equipment slots so can be configured for different roles. Okay, also been playing NMS and enjoying the latest update...

I hurt my back a week ago and that put me out of action for a week. Good news is I'm recovering, feeling much better today, so can return to programming soon. Played NMS a bit this evening and back was okay. Should be back to 100% soon.

C64 #Delphian progress: here's a little WIP clip showing taking off from a planet, leaving orbit, accessing the navigation computer, plotting a course to a planet and using Stardrive to get there. A bit rough and still with more to add, but thought people might like a look.🙂

C64 #Delphian progress: still working on this BTW. Latest additions include getting the solar systems working (with 2 - 6 planets), WIP on solar system chart, and the addition of a Stardrive for fast travelling within a solar system. I should perhaps make a progress video soon...

SarahJaneAvory @sarahjaneavory.bsky.social · 12/08/2026

I keep thinking I should make another C64 SHMUP. I did think Zeta Wing 3, but I'm out of ideas for that, so might consider a full version of Neutron... Hmm...

C64 #Delphian progress: added an image for the cargo bay, so here's another WIP video clip. Thinking of updating the image with cargo canisters as the cargo bay fills up...

C64 #Delphian progress: I've created an interior image and I quite like it... so I hooked it into the game. Anyway, here's how the game looks at the moment.

C64 #Delphian progress: just for fun (as I can't use this image) a ship interior! 😀😊😉

SarahJaneAvory @sarahjaneavory.bsky.social · 31/07/2026

C64 #Delphian progress: all bit more optimising today, but I think the next step will be adding all the ship systems, meaning items to purchase and install. Some items can be upgraded if you find a Technician and give them the right items... Oh, I need a currency too! Credits will do I guess...

SarahJaneAvory @sarahjaneavory.bsky.social · 28/07/2026

#C64 #Delphian progress: life's been a bit up and down recently, but it's okay now. So, did a bit more work on the game, getting the star chart to work. I can now select a destination star system (that's in range) and jump there. Still some optimisation to do, but here's how it's looking so far...

SarahJaneAvory @sarahjaneavory.bsky.social · 15/07/2026

#C64 #Delphian progress: bit more work on the hyperspace effect this evening. Also added fade in/out on cursor, plus added a charging message and bar.

SarahJaneAvory @sarahjaneavory.bsky.social · 14/07/2026

#C64 #Delphian progress: been working on a hyperspace effect this evening, and this is what I have so far... Oh, and star chart is kinda working already, so soon I'll be able to jump properly between stars.🙂

1213010

SarahJaneAvory @sarahjaneavory.bsky.social · 02/07/2026

#C64 #Delphian progress: this is still a bit rough, but here's the latest video clip. From planet surface to space, and back again to landing on the planet and walking around. Needs a bit of optimisation in places, then comes a hyperspace jump!🙂

49817

SarahJaneAvory @sarahjaneavory.bsky.social · 01/07/2026

#C64 #Delphian progress: I have a planet (okay, circle) in space, and can fly around it. Just needs the enter orbit code finishing, then I can take off, fly into space, turn around and return to the surface. Next comes hyperspace jumps, star charts, info, shops, items... rest of the game really. 😉

SarahJaneAvory @sarahjaneavory.bsky.social · 28/06/2026

#C64 #Delphian progress: minor update as I've just added the horizon curve at high altitude. Next step is to add a planet in space (and I have a circle draw ready for that). Then comes re-entering orbit, and then return to surface flight. Oh, and did I say I'm having lots of fun with this?😀🥰

A cockpit view of my WIP C64 game Delphian, showing the horizon curving at high altitude.

SarahJaneAvory @sarahjaneavory.bsky.social · 26/06/2026

#C64 #Delphian progress: finally got the code working for the transition from flight to entering space. Still WIP and a bit rough, and I still want to curve the horizon at high altitude. But here's what I have so far, from walking around, boarding a ship and flying around, to heading into space...

810824

SarahJaneAvory @sarahjaneavory.bsky.social · 24/06/2026

#C64 #Delphian progress: reorganised code a bit to make better use of ROM. Added some dsshboard code, added code to handle altitude (complete with sky fade and horizon dropping), so I've nearly reached space. Looking at curving the horizon at high alt. Then it's time for another video clip!🙂

3422

SarahJaneAvory @sarahjaneavory.bsky.social · 22/06/2026

#C64 #Delphian progress: back to the surface! I'm coding up the main game flow, so added code for walking around, boarding a ship, taking off, flying around a bit, landing, getting out of ship. Turning feels smoother after adding 1024 entry sine table. So next step: heading into space...

SarahJaneAvory @sarahjaneavory.bsky.social · 17/06/2026

#C64 #Delphian progress: modified my own 3D model editor to output files for the C64, so now I have a spaceship in game.🙂Lots of changes to the 3D engine to support polygon types: points, lines, triangles, quads, and pentagons. Solid polygons might be playable on a 1Mhz C64...🤔

SarahJaneAvory @sarahjaneavory.bsky.social · 14/06/2026

#C64 #Delphian progress: been working on the clipping code for my 3D engine. It's now working, and today optimised the code a bit to run faster. There are two code paths for clipped and unclipped, tthe slower clipping code only used when needed. It's been fun code to write!😀 That or I'm a bit mad.😉

SarahJaneAvory @sarahjaneavory.bsky.social · 10/06/2026

#C64 #Delphian progress: still WIP and a bit rough, but solid polygons are now working.🙂 Time for a bit of optimisation... My aim is to give the player graphics options: wireframe for speed, solid for visuals (and sacrificing speed). Of course a 64Mhz C64U will have no issues with solid polys.😀

57913

SarahJaneAvory @sarahjaneavory.bsky.social · 09/06/2026

#C64 #Delphian progress: not the most impressive video clip ever... but here's the WIP 3D system showing wireframe with hidden surface removal working. I still need to optimise some of the maths further... then the next step is (probably) solid polygons!🙂

610612

SarahJaneAvory @sarahjaneavory.bsky.social · 02/06/2026

#C64 #Delphian progress: here's a little WIP video clip showing a bit of walking around, the WIP galaxy chart, and of course a bit of flying through space with my new circle draw and some space debris.🙂All this is on a stock 1Mhz C64. More to come...

48813

SarahJaneAvory @sarahjaneavory.bsky.social · 02/06/2026

BTW, I still plan on working on Spectrum Next Delphian, but will complete the C64 version first. I have a PC version in C++ that emulates C64 graphics (and SpecNext too), and I use that to prototype code. I can then port the C++ to 6502 and Z80.😎

SarahJaneAvory @sarahjaneavory.bsky.social · 01/06/2026

Not been feeling motivated for a while, but recently have returned to #C64 #Delphian. Settled on a galaxy size of 1024 stars, and have that working on the C64. Also started work on a C64 3D engine. First thing: circle draw code. That's now working, but a bit slow.

SarahJaneAvory @sarahjaneavory.bsky.social · 13/05/2026

#C64 #Delphian progress: revisited the galaxy generation, and now it's down to ~5500 stars. Feels like a better number. Also, sorted through my paperwork from the 80s version, so next step should be a complete game design.🙂 Might look at doing polygons too, but that might be a bit too much...🤔

5464

SarahJaneAvory @sarahjaneavory.bsky.social · 12/05/2026

Been working on the proc gen system for #Delphian, my #C64 space trader. With the code I have now, I'm currently looking at a modest sized galaxy of 266484 stars, with each star having 1-8 planets.🙂 Plenty to explore! Or is that too big...?🤔

SarahJaneAvory @sarahjaneavory.bsky.social · 10/05/2026

After a bit of optimising (screaming at screen when it wasn't working, overjoyed when it finally was), here's WIP C64 Delphian running on a stock 1Mhz C64.😀 It's around 2-3 times faster than it was, and there's still more I can do... Should be pretty zippy on a C64U at 64Mhz, so will try later.🙂

1110817

SarahJaneAvory @sarahjaneavory.bsky.social · 08/05/2026

So Delphian C64U running at 32Mhz... Runs a lot slower at 1Mhz, but the idea would be graphical settings to let the player decide between more detail and slower speed, or less detail and more speed.

SarahJaneAvory @sarahjaneavory.bsky.social · 28/04/2026

A bit more work on a possible #C64 version of Delphian, my unreleased space trader from the 80s. This is running on a stock C64, and with interrupt driven controls it feels playable. I'll have to test with a lot more sprites on screen, but I'm happy with it so far.🙂

511012

SarahJaneAvory @sarahjaneavory.bsky.social · 28/04/2026

Seriously thinking of getting an electric car, so obviously I'm looking at getting a Tesla... Er, only kidding! Going to testdrive a BYD Dolphin Surf this weekend as I like the way it looks, and the specs are good for me.🙂

SarahJaneAvory @sarahjaneavory.bsky.social · 22/04/2026

Zzap! Live in Coventry UK is coming up in May, and I'm thinking of going...

SarahJaneAvory @sarahjaneavory.bsky.social · 20/04/2026

Been messing about with some C64 maths code for a possible version of Delphian. At 1Mhz on my C64U it's a bit slow, but probably playable for what I need once I add interrupt driven controls.

SarahJaneAvory @sarahjaneavory.bsky.social · 10/04/2026

Sometimes I bounce around a bit on projects, so yesterday evening was experimenting on the C64 with an 8bit x 8bit multiply that uses 2 table lookups and 2 subtract instructions. Could use this on a C64 version of Delphian, my old space-trader game...🤔

1342

SarahJaneAvory @sarahjaneavory.bsky.social · 08/04/2026

I thought I'd lost all my paperwork for Delphian, a 3D space trader for the C64 that used large scaling sprites... but I found it all last night!😃 So now I'm imagining the game running on an overclocked C64U (or similar)... 🤔🥰

#C64 #Kouyate #RPG progress: a quick little video clip showing a patrolling enemy on the world map who spots me and gives chase!

SarahJaneAvory @sarahjaneavory.bsky.social · 07/04/2026

Realised I've been a bit quietly... Well, still working on #C64 #Kouyate, making good progress on the world map creature spawning and logic. Hoping to post a progress video clip soon...

SarahJaneAvory @sarahjaneavory.bsky.social · 30/03/2026

Music this evening: started with some ELO and ended with Judas Priest's Painkiller.

SarahJaneAvory @sarahjaneavory.bsky.social · 30/03/2026

#C64 #Kouyate #RPG progress: one thing that's missing is the overworld enemy spawning. I could make life easy and just have random encounters... But I'm looking at adding a spawning system so you can see the enemies and decide whether to engage or avoid; get too close and they will fight or flee.

5344

SarahJaneAvory @sarahjaneavory.bsky.social · 27/03/2026

#C64 #Kouyate #RPG progress: I'm finalising everything from the start onwards, so the first two villages are now populated, with most of the scripting work for them done. Had to make a few changes to fix the flow, but it's better now and I'm happy.🙂 Feeling much better about things these days.🙂

#C64 #Kouyate #RPG progress: been thinking... and I think I'm going to add multi SID support so I can use one to play the music, and dedicate a 2nd for just SFX.🙂

Been a bit of a wait but... I had a delivery today... 😀🥰

#C64 #Kouyate #RPG progress: finished the code for health and magic restore items, both outside of combat and during. Code is structured so I can easily add more items if needed. So I can cross that off my to-do list.🙂

2484

SarahJaneAvory @sarahjaneavory.bsky.social · 18/03/2026

Hoping to get my Founders edition C64U soon... Hopefully... And hoping it'll restore my motivation to make more C64 games!

SarahJaneAvory @sarahjaneavory.bsky.social · 18/03/2026

#C64 #Kouyate #RPG progress: still struggling, and I think it's because the game doesn't feel right. So I'm ditching my original plan of getting all the locations done first, and instead am finalising everything from start to finish. So today began adding health and magic restore items.

1262

SarahJaneAvory @sarahjaneavory.bsky.social · 09/03/2026

#C64 #Kouyate #RPG progress: after a break, I'm back onto this! Reworked some weapons code so now I can have 62 weapons and 64 armour items. That should be enough... But now my save games are broken, so I'll have to play through the whole game again...🫨
