New member does Sidplay2 in Java

Hi folks,

I am a new member of CSDb and want to introduce myself
with a little release.
First, i am very proud to be accepted as a new member of the scene.
For short: I am a C64 fan from 1986 until now.
I was never active in the scene, too less talented maybe, but i learned basic and assembler and did some coding for myself in the past.
One thing from the past i actually do until today is listening the precious SID music of all the talented music artists. So many thanks to all of you for your work
collected in the HVSC.

To listen the new releases from the still active groups i often used sidplay2 for windows or an emulator like CCS64, because my commodore was on the attic.
I am also a Java developer and wanted to have my very own java implementation to create a so called C64 Jukebox.
I decided to create a 1:1 conversion of sidplay2 from C++ to java. It should have all features of the original.
It was a long time work and when it was finished i decided to make it open source, that others can integrate into their java emulators.
Perhaps there will be plugins for many java apps some day or a version running even on a mobile.

If you have any suggestions or feedback (positive or negative) it is welcome.

Have a lot of fun with our hobby,
Ken

Excellent! I'll give a J2ME port a go when I get the time, but I wouldn't keep my hopes up for most phones. The Motorazr2 phone could have a fast enough Java VM for running sidplay2, and so could perhaps also some of the latest Sony Ericsson models, but I reckon that'd be about it.

For SLDb configure like this:
Edit ~/sidplay2.ini (C:\users\<name>\sidplay2.ini)
Songlength Database =<hvsc_dir>/documents/Songlengths

The INI file is created, if it doesnt exist.

What about the Nokia N95? Not that I have one but I think it features some extra multimedia chips or something (at least for video).

I myself have a Nokia E61i and a Samsung u700, guess I'll miss out on the fun with both of them :( I did hear about a sid player for phones running Windows Mobile on them though.

Very nice port, works flawlessly. However, it is very CPU intensive, compared to c++ sidplay2. On my 2.7 GHz Athlon X2 it uses about 20% CPU time, while sidplay2 hovers around 1-2%. :)

TDJ: Sound playback isn't expensive at all compared to emulating the SID and 6510. Doing SID players for Windows Mobile or Symbian is much less taxing than for J2ME, since both Windows Mobile and Symbian run code natively rather than in a VM. Both the Motorazr series and the standard (non-Symbian) Sony Ericsson phones have got very fast Java VM's, so it's worth a try.

That being said, I don't believe any mobile phone SID players for either Symbian or Windows Mobile are based on sidplay2/ReSID.

Hi folks,

I am currently working on a GUI for jsidplay2,
i have now some graphical output.
If somebody wants to have a sneak preview,
here is it:
http://mitglied.lycos.de/kenchis/jsidplay2.jar

Start with java -jar jsidplay2.jar
Tell me your ideas.
For example i think about a sheet of music
displaying the current note.

Have a nice weekend,
Ken

Thanks for your effort, but the final result isn't too appealing to me, sorry. Those displays add no extra value to me, I'd rather have a simple GUI with some extra features that other players lack. For example the ability to activate single channels or switch SID model on-the-fly.
