Commander X16

The DOS and Tandy versions of AGI games are the same files (that's the whole point of an interpreter lol) except for very early versions of Kings Quest. For the DOS interpreter it just plays the first voice in the sound file. I got 3 voice sound working on the PSG. I wrote a player for AGI sounds. ...

I seem to remember these sounds in the original Tandy version also (which had a 3-voice audio). I might be mis-remembering, but as I recall King's Quest was an "in secret" launch title for the PCjr. IBM had Sierra do NDA's even about it. Then when it launched, IBM used their typical (gray...

However if it would make for a better demo I could swap two and three? Is that your motivation? Well, I put it this way: the AGI support on the CoCo3, they never managed audio support. So it would be nice to see that it is something an 8-bit system could pull off (via delegating to a support chip)....

Thanks for the update, and the screen shots - the fairy, troll, and the well!!! Good memories. Still, I want to HEAR this game, someday ^.^ (oh, we can dual X16 it, use serial card to cue another X16 to play the audio with a few command bytes :P ) Hi Xiphod, Glad I could take you back to good old d...

Thanks for the encouragement

CommanderX16 February 2025 AGI Update I have an update regarding my CX16 AGI Interpreter. shortExport.gif Over the past few months, I have completed three major tasks: -Implementation of double buffering: The 3D effect mentioned in my previous post requires redrawing of sprites. To prevent this redr...

The engine is looking close to finished! Well done on the job! Are the views sprites or drawn to the bitmap layer? In my version I was using sprites which presents it's own challenges but I always assumed they'd be faster than a heap of pixel gets/sets. I had sound working in my unfinished implemen...

Yes, this is running on the Commander x16!

This post is to provide an update on the Sierra AGI Interpreter I’ve been working on, which I’ve previously shared. The focus over the last three months has been on achieving a 3D effect. If you’re unfamiliar with these games, they were marketed as “3D” back in the day, though they are what we would...

This post is regarding my Sierra AGI interpreter for the CommanderX16 on which I have previously posted. The last big block of work focused on drawing the screen faster, reducing screen algorithm memory requirements, and drawing the priority screen. I used an algorithm by the Scanline algorithm by C...
