dunno if somebody noticed, but the white and black squares on the chess board of the chess game are the wrong way round...

anyway, I need some help with the following: I get disc errors when starting some (well the majority) of the apps (error code 18).. I cannot see any pattern to it..the files seem to be ok. I am starting symbos from a partition on a cf card in a carnivore2 cartridge.

Sepulep, I get the same problem. No idea why this is, hope some help is out there.

hahaha, that is a bit stupid, and we never noticed, lol

The chess game was never really finished but we should consider now to make the board at least correct

About the error 18. It means (Error in File Organisation) Is this in every file you try to open? Or do some applications work?
Is it random? What kind of FAT partition do you use?

I think the bigger question is, is already confirmed that Symbos will actually work with c2? As Symbos uses it's own driver for each device, I wonder if a specific c2-driver is already available (despite being sunrise ide compatible afaik)

Edit: i read in the existing c2 announcement topic (page 3,4) that this is also/already discussed. And that theoretically it could work with the existing sunrise ide driver. But did someone already tested this, and can confirm that it works flawless?

Also keep in mind the cf-compatibility list (as mentioned by alexey in the same topic) which could also be part of the problem.

hehe, the chess app felt a bit wrong...took me a minute to notice the board..

some apps work (such as chess, the system apps), (most) others not, and it is consistent (ie working app always works, non working always fails), the cf card (actually an sd in a cf adapter) is partitioned to 4 file systems, the symbos one being the second, formatted as 32MB fat12.

It worked fine with symbos 3.0 (at least I never noticed any problem)..though I have updated the carnivore firmware and tooling (such as the IDE bios) (from 1.7ish to 2.52/2.50) since..

@Sepulep, sorry, I didn't notice before that you are speaking about the C2. Is there any information about differences to the Sunrise IDE on hardware level? I never had a deeper look at the C2 before (and didn't know, that it is "sometimes" working in SymbOS as well). But this is something I can do now soon.

I am currently working on the Sound Daemon for SymbOS (the third daemon after the Network Daemon and EdoZs Printer Daemon).

PacMan now with sound:
https://www.youtube.com/watch?v=4k0BmLr_1es

It allows to play music and sound effects in any applications. Supported sound devices are the PSG and the OPL4-wavetable part (Moonsound etc.), as these two devices are available on nearly all SymbOS platforms.
An application can load one music collection (containing multiple songs) and any amount of effect collections (containing multiple sound effects/samples).
The OPL4 music part is based on the MOD player by Maarten Loor/NOP, thanks a lot for this great work! It is using an own optimized format which can merge multiple MODs into one file, sharing the same samples, which may save a lot of wavetable RAM. Pattern data is compressed at an average ratio between 1:4 and 1:5 and is uncompressed on-the-fly during playback.
I am thinking about adding S3M (ScreamTracker 3) support, too, there is still place for the extra volume information in the pattern data. Anyway 8 channels would be a realistic maximum, otherwise it would use too much CPU time I guess.

ok, it seems that symbos is mostly working on the carnivore 2, ie the setup program and it starts up fine..the system apps work (settings etc, command line)..the only thing that I have noticed is the app issue and the fact that changes in the configuration don't persist to the next boot (dunno if that should be the case though)..

hmmm, according to a comment on https://msx.org/forum/msx-talk/hardware/carnivore-2-setup-0?page=1 one needs to write to the sd card through a cf reader and not directly on the sd card (SD reader)...I did the latter...

The sound daemon added so much to SymbOS! I really love it!
