We have an iMac G4 at work that might still work. (It is currently used as a picture frame, and I don't mean digital picture frame.)

If this system fits your needs, please describe what you need done (or link to a post/article/... describing it) and I'll see what i can do.

Thanks for the offer, sorry about the delay. All I need is an OPL capture - run DOSBox, start a capture (Alt+Ctrl+F7 by default) and run something with Adlib music (try this bbstro if you don't have anything handy.)

Leave it running for about 15 seconds (that's all I need) then press Alt+Ctrl+F7 to stop the recording and you should have a .dro file created. If you can post that here it'd be very helpful!

shouldn't .dro created on every computer be the same? Isn't it a bug of dosbox that it is not?

Possibly. Often for efficiency reasons the bytes will be swapped on big vs little endian architectures (see Wikipedia for details) so whether this is a bug or not is open for discussion.

Of course it only *looks* like it will happen, I'd need to see a big endian capture first to be positive.

I think that if a big endian capture happens to be positive the thing to do first would be to try to make dosbox code not endian specific, and patching your player only if it couldn't be solved that way.

I guess that's up to the DOSBox devs to decide. The code could certainly be fixed, but whether anyone is willing to do so...

if it gets captured wrong on big endian than is a bug. Would be easy to fix probably.

I'll try it out next week (if the old Mac still works) and post the file for analysis.

Here is the file. It is renamed, not zipped.

(edit: forgot the file)

If you need big endian, basilisk or sheepshaver mac emulators will do.

Ah excellent, many thanks for that koun! It looks fine and plays without any trouble, so that answers my question. No bug in DOSBox 😀

Thats good news. Glad I could assist.
