Not a lot to say about this. It plays music through the serial port of a 9860gii (or hacked 9750gii, or hacked 9860g, etc).

I thought it only worked with the SD version.

I thought it only worked with the SD version.

That was the one Martin Poupe made.
This one was made by me, and embeds the music inside the .G1A file (since I don't have an SD calc) - so it can't fit very music music.

The chiptune shown in the video compresses to ~3000 bytes/sec, so I could fit 8-9 minutes in the 1.5MB flash memory.
Most music doesn't compress at all (I'm just using simple RLE compression) and takes ~3900 bytes/sec, fitting 6-7 minutes total.

Cool man! Great Job!

Where can I download this magnific program ?

Source code:
http://www.mediafire...l0gwmk9x25g9124

I cleaned it up a bit before I uploaded it, but I can't test it right now. PM me if it doesn't build since I'm not usually active on these forums, and I get notified of PM's by email.

How to build:
* Convert your music to an 8-bit unsigned WAV file. If there isn't an option for signed/unsigned, in whatever program you use, then it's probably unsigned by default.
* Save it as audio.wav in the converter folder (or change the converter's main.cpp to point to it)
* Open main.cpp in the converter folder, and change the following options if necessary (they're all near the start of the file):

// This isn't actually bits-per-sample, it's 2^bits-per-sample.// Supported values are 2 and 4. If 4, uncomment TWO_BPS in the player.#define BPS 2// if uncommented, creates a file out.wav containing the exact sound the// calculator will play. Doesn't work properly - the resulting file sounds// nothing like the calculator's output.//#define WRITE_WAV// uncomment if a chiptune created with Beepola#define BEEPOLA// uncomment if stereo//#define STEREO// must be 44kHz 8-bit WAV#define INFILE "audio.wav"// maximum output size. It may go up to 255 bytes over this.#define SIZE_LIMIT 1200000

If you aren't familiar with C/C++, then "uncomment" means to remove the // at the start. You probably want to re-comment BEEPOLA, by re-adding the //. The chiptune I used in the video was made with Beepola.
* Compile and run the converter, this generates out.cpp in the player's folder.
* Build the player using the CASIO SDK, and upload it to your calculator.

Thank you for releaseing the source code.

[Binary_man]

Thanks for you work. I will PM you more later for the result.
