Hi igal. Sounds excellent! I'm impressed that you managed to reverse engineer the rom and put your own music in it. If you want I can send you the source code so you can change image or change the length of the sample, or even do a 1024KB version. Let me know if you are interested.

Hello dvik. (Sorry for the google translation)

I used of malice to find the starting location of the music.
1) I started with the idea that music was sampled at 15Khz approx)
2) I Imported [Leila_K.Rom] with [Audacity].
3) Identified and cut very precisely the sample
4) Once you have found the exact weight of the music, I could subtract the amount of bytes on the total capacity of the .ROM. So I got the supposed starting address in ROM 0000 6000.

I Flate you have offered me Leila_K sources, but I must confess that I do not have enough knowledge to take part.
However, I'm sure if you put your sources available to the community, many people would be very interested. Wink

I tweaked the settings and the current state LEILA_K demo application loop [32Secondes and 236 mils] to music without hatching.

The trick to obtain very precise timing that is playing on the frequency of music NATIVE so to get closer to the maximum.

Specifically, for the piece that follows, I adjusted the length of the song by transforming an MP3 [44100Hz => 31Secondes and 870Millième] in [43600Hz => 32Secondes and 236 thousandths]

And when a more applications of this kind of tools using digitized sound samples? I mean in games or something. We have more examples for PSG too and yes I assume that the MSX cannot do much more when sound or music is playing but we could try to benefit of it in some way. Are them really useless in a game? I would like to know the point of view of coders.

Hi dvik.
I come back to you regarding your proposal to the source code of "Leila K" demo.
In fact I'm very interrested in the source code, but I can not reasonably operate without help.
Today it's done, since member has offered to work together, thus allowing me to take part in the sources of "Leila K".
I prefer to be clear about the future of your sources are confident that you will be working on two.
Whatever your answer, thank you for giving me the proposal, and I perfectly understand if you do not want to distribute the sources to two people.

Thank you. Wink
