Cool!
Ah, here is a adaptor layer by @peli .
So the [World race](https://forum.makecode.com/t/world-race/13543) must migrated based on this layer.
And I just optimized pattern fill in game, maybe should add them together. I am going to share my version recently. Do it now!

It’s just a compat layer for pico 8 tweetcarts

Is there any reason why advanced games and performance is contingent on this pico-8 compat layer and cannot be implemented just as well or better directly in MCA?

I keep forgetting to mention that the pico8 compat layer was made by @peli

I don’t think world race used this compat layer, just translated the code into makecode arcade

That’s CAN be implemented just as well or better directly in MCA, absolutely!
This layer is just for convenience of migrating from pico8, nothing else. Everything you saw is MCA.
The reason seldom demos appears, I guess, is Arcade features and guys in this forum are both caring about making games more, instead of demos.

Some speech or other _outside of the box_ sounding music or sound effects, which @randomuser is researching, would also be very interesting to add to a demo project!:

> TL:DR at bottom! I sifted through the hardware code of Makecode arcade and found how it runs sound effects! I was hoping to find some sort of sound file player, but instead they simply play a bunch of sine waves just as we can in the coding menu. Although they do have some extra shapes beyond just sine, square, sawtooth, and noise! That’s how they make the other stock noises in Makecode arcade that we cant, like the other notes in the melody player and the sound effects. I also found that for …

funny. And have a look on this [Speako8 Speech Synthesis Library](https://www.lexaloffle.com/bbs/?tid=49108)
I also digged into synthesizer codes a little when I make my karaoke project, and later try to migrate the pico8 World Race. Found one of potential issue is that volume is not set by note, but set by whole “package”. And seems also not as many as pico wave shapes, and other effects either. So maybe hard to make same sfx node of pico8, and would be harder synth speach more natually.

And this: [Sample Sandbox](https://www.lexaloffle.com/bbs/?tid=42809)
Difference ways with prev one. This more like a player playing pre-recorded mp3, while the prev seems syths on air. (havn’t have time to dive into them more)

Amazing work! And I can see that you have made almost a full demo with great graphics and music already with this awesome “Bad Apple MV”:

MCA music just improved yet another notch for even better demos!:

How would such improved and custom instruments work with your midi and other music extensions, @UnsignedArduino?

Unfortunately, it wasn’t made with the Song instrument format so my converter can’t use it. The sounds are quite cool though - hopefully these are ported over to custom instruments that can be used in a Song!
@richard had a tool that allowed you to experiment with instruments that can be implemented in the Song format, but I can’t find the link for it.

These sound really wonderful, tune colour of instruments are emulated, can be identify easily.
But like @UnsignedArduino said, they are not implement by instrument, can’t applied into other game directly. At least, it shown a possibility of beautiful instrument in MCA.

Another GIANT leap forward for the MCA demoscene!!!:
