Nice!  Does it have any noticeable effect on speed?

It's hard to really tell, since there's no FPS counter oncalc. But in Wabbit it seems to still run fullspeed. The game is really designed to run in 6MHz, so I have 9MHz left to process sounds.

Some of you may have noticed a bit of a beeping noise replacing the percussion about half the time. I've fixed that by increasing the frequency of the white noise channel. Much better-sounding track here.

Awesome music!  Is there going to be more than one track?

First I'm going to have to decide my final storage method for the music (it's pretty freaking huge at the moment). But yeah, I'll probably have multiple tracks, and I'll try to add in-game sound effects as well

Epic sound. I can play some part of it in a guitar. xD

Will be added sound to events like death, fall, kill enemies, etc? I love the things that calcmaniac84 can do. I hope I can do some of my own, someday. ^^

O_O
Dude, this is really on calc music? o.O If so, I would very very much like to have your most current build to throw on the calc and try myself.

It would be cool if he joined. Is he just too busy to join atm?

For music, he would probably have to convert the music into ASM readable format, since I assume calc84 uses a quite unconventional type of music data for his game

aaaah ok I see. Remember he can always also check out other music too and comment even if he doesn't post about his yet. Plus, sometimes on forums other members appreciate when a new member give feedback on their stuff if the new member showcase his, rather than just joining a forum for the sole purpose of showcasing their work without posting anywhere else. Some people even see the later as bad netiquette and there are even music forums where you are forced to have 10 or 20 posts before being allowed to showcase your own work and some forums requires you to comment on 5 or 10 songs before being able to showcase anything else again

That music is incredible, great stuff!

I wonder: does the addition of sound have a huge impact on the game speed (and grayscale) performances? I know some sound programs won't leave much time for other stuff to be executed unless the sound is only small beeps, like Ice Climber and Pyoro

Nope, not at all, because at 15MHz there is (or was, before I added the sound) a ton of free time every frame. The sound effectively reduces the available clocks to 6MHz or so, which is what I am designing the game for.
