Got slightly distracted and started looking at the final disc/tape loaders..... 🤯

Exomising the entire game image to reduce footprint / tape load time. Compression ratio about 50%, which will do !

Here's a visual representation of both files - zipped/unzipped !

So to celebrate, I've opened up the first article to everyone. I'll open up more in the coming days - Enjoy!

And yes, the game for the Acorn Electron uses Mode2 as you know and it is much more flexible even having just 8 colours as there no restriction on pixel placement. This other machien will have colour clash if I have more than 2 colours per line where the sprite will be moving. Happy with the result.

I usually use Exomizer but today a friend told me about this one: github.com/einar-saukas... .I’ll have a look to see whether it’s worth making the change to start using it instead or if it is better in certain scenarios. Nice you managed to do what you wanted with compression! Cheers mate

#8bit #gamedev #retrogaming Will I be able to fit this in a 16kb cartridge? Working on it! PNG of just a test for the 6 fully masked sprites. I have 4kb free, but also the rooms are all in & are not compressed so I can get back some kb I hope ;P #indiedev #pixelart #ドット絵

"Astoraid" but not running on an emulator/real hardware. I've created a mini dev environment using JavaScript + an HTML Canvas that lets me try things out much more quickly than writing lots of 6502. I have a library of routines that mimic the real hardware so the code is close to what it will be...

Just ordered the C64 Ultimate from commodore.net !! I will have to wait some months to receive it but I am very excited about having a new C64.

I haven't posted an update on "PET Invaders" (WIP) for quite a while.
State of affairs: basic gameplay is finished, any progressions based on shot count are still missing, as is sound. But we're getting there…

....Where was I ?
That's a couple of geese/hen issues sorted out. They eat the grain a lot faster, so shouldn't be able to rotate to the edges of the tower while eating !

Lower geese clipping sorted as well - this ended up a bit messy, but at least you can see them down there !

Spectrum Next #Delphian progress: been working on the transition into space, and it's almost there... just needs a starfield, planets, the sun... Oh well, one step at a time...

I've also been rearranging code to use RAM banks so I only bank in code that's needed. Anyway, starfield next!😀

Secondly, the geese attempt to flip orientation as they walk around the back of the silo.
The silo circumference is 16 bricks, each split into 3. Depending on which fraction Harry is in depends on how the geese flip looks - one looks ok, the other two not so much ! 🤯

So on to some geese/hen issues. Firstly, the geese (I've always called them geese) should eat the grain when they're in full view, in the middle of the screen, not at the edges. Sometimes if Harry runs quickly in the opposite direction, the goose is still eating the grain at the edge of the silo...
