X65 computer

Presented the X65 Project at Games & Vintage Days Wrocław 2025. The response was great! 🎉 People kept coming over, asking questions, and showing real curiosity. Many were impressed by the idea, the execution, and the look of the machine.

🎂 How to know if the caller is an AI, just ask for a cupcake recipe! lol …

What game is this?

There are also dedicated Matrix rooms for X65 subproject in this space: - #sgu-1:chrome.pl - #k816:chrome.pl - #cc65-dbg:chrome.pl

Alrighty… Since everyone is moving from Discord, to [Matrix], I think it's our turn too… I've created an X65 Community space at: #x65:chrome.pl You are free to join with whatever Matrix account you have… 😆

Mystery Cannon playing over HDMI audio... 😆

Coding in K65 with language server running in background is fun…

K816 language server is working…

@RetroCogs @BZbytniews42467 C calling convention is not something that you can efficiently run on 3 registers.

@X65pc @BZbytniews42467 Did you consider Calypsi? github.com/hth313/Calypsi…

I was looking for a high-level-assembler that will make my life easier, writing OS/816. The closest one to my needs is K65, but @BZbytniews42467 has issues with it… So I decided to rewrite it and adapt to 65816 on the way… Meet K816: github.com/X65/K816

Can you build a HLA (high-level-assembler) in 24h? Oh yes, you can… Meet K816: github.com/X65/K816 a #HLA for #wdc65816

This time: X65 sound chip SGU-1 serving as a stand-in for the SoundUnit, Amiga Paula, and Atari POKEY. youtu.be/D6siCQn1aQQ

Over the weekend I've rewrote SGU-1 replayer for Furnace from scratch. ESFM plays almost perfect. youtu.be/KAy1JujoTXI

Now it is time for some compatibility tuning…

Added SGU-1 sound chip to Furnace chiptune tracker.
