2 SID C-64 help needed

Hello all 2 sid c-64(PAL) owners!

I cordially request your assistance.

You can help, if you have a setup that has C-64+2xsid+1541 or compatible floppy drive and can transfer and run following disk-image on your setup and report on whether it works or not, any glitches, and in optimum case provide recordings of the output and name the sids used.


http://www.sid.fi/~mixer/test.d64

note: This is not yet the final release.

Program allows loading and playing a 8khz stereo sample using 2 sids showing simple oscillator graphics. Current version can load and play from $0300 up to $ffff, though oscillator sprites will be overwritten above $ff80.

Program has been developed with Vice x64sc 2.3 x64.
- 2nd sid at $d420, filters on.
- True Drive Emulation on.
- For best results use 2 x 8580

Program allows you to select your 2nd sid location. All legal sid locations between d420 and d7e0 should work.

Sound output is garbage with single sid only.

A word of warning, the program does not handle $01 very kindly. Motor is on and the tape out bit is overwritten, so it may be worth disconnecting your tape drive if you have one to avoid accidental overwrites.

Also, IMHO it makes no sense to add these files to HVSC or CSDB as they're just simple sampleloops after all.

3. resample it to 7819hz (Change project sample rate to 7819 also, otherwise it'll output 44.1)
4. export it as raw 8bit unsigned pcm.

or for makefile affine people, something like this :)
sox -D input.wav -t raw -r 7819 -b 8 -e unsigned -c 2 output.raw gain +3 bass +5
