Yes, a full cart could be made with 256 songs on it.
But a full cart could be also be made with only 1 song on it.
there are a lot of factors affecting how much data a song takes.

I can only relate my own simplistic case (the music for sudoku which I still havent finished)
I plan on using only 1 sound register, playing at a fixed rate, and having a relatively small number of notes (lets say 16.  Since I havent done it yet)

I'll need 16 notes (4 bytes each) = 64 bytes for my note table.
I play back at a fixed rate (1 note per 1/5 second)  so 256 notes (stored as an index to the note table) is another 256 bytes (128 bytes if I use 4 bits instead of 8)  and that would give me 51 seconds of audio for my music before it loops.   Thats tiny,  but its also not going to be very good music.


I would imagine Vegavox uses all 4 main sound channels and possibly the DMC channel.
If his song was longer than 51 seconds, it would need more data.
If he used all 4 sound channels, you are looking at at laest 4 times the data I listed above.
If you dont use fixed spacing (I was usign 1/5 of a second) , additional data is required.
If more than 16 notes are being used, you can use the simple byte paking I mentioned above, although compression would still be possible.
I know that if the DMC channel is used, enormous amounts of space can be required)

Very cool item, I picked up one as well.  We have had lots of new NES projects lately with this, NWC repros, and the newly released PowerPaks.  Very exciting time for NES right now.  Thanks for the link.

6/11/07 should go down in Nintendo history for all the homebrew releases:

Vegavox
Powerpak
and the 2nd batch of NWC 1990 repro carts

Very good day to be a nintendo fan!

Yes.  But keep in mind that I have no musical talent.  So all I am doing writing audio playback code and an audio composing tool so I can play "Feur Elise" by Beethoven.  Its a public domain song, my version will suck, and I'm pretty sure no other NES games have it.  I havent worked on it in over a week.

not to mention the amazing selection that's starting to build up over at gamereproductions.com . He just got more chips for the snes dragon quest 5, plus he's got cocoron up for sale now.

definately a great time to be a nes fanatic.

I got mine yesterday.  Very cool little item.  I listened to all the tracks once over, not bad. I doubt I will just be sitting and listing to it all the time or anything, but very cool.
