Re: 4GB SD cards may not work in SDHC devices

Those details don't really matter; SDHC cards require an extra initialisation command that non-SDHC devices don't know how to do.

I've got one of those Transcend 4GB cards, it operates in both SD (byte addressing) and SDHC (sector addressing) modes depending on how it's initialized.
Re: DOSBox Feature Request Thread

Basically telling dosbox to close the capture as soon as it's near 2GB (in this case I used 1GB just to make the file sizes more manageable) by a configuration variable. Because the flag isn't reset, Dosbox opens a new file at the next frame, thus no capture data is lost and is essentially …
Re: Delusional performance of a 486 DX33

That simply isn't true; compact flash in most cases doesn't support DMA and ends up slower than actual IDE drives. Its advantage is simplicity and convenience, not speed.

sys_icache_invalidate() is better on OS X anyway. I'm not sure, the docs don't mention it performing a data store/flush before invalidating plus it seems wasteful to make a syscall to perform non-supervisor operations. If this was portable code it would be a no-brainer but given it's explicitly for …

What exactly was the problem with the inline asm?

Don't forget Duke3D also has a screen size setting (as well as resolution selection) which makes a significant difference.

I think it should still apply cleanly, if not it's no trouble for me to update it.

Scali wrote: No card is 'free' of the single cycle DMA click. And it's not really a bug. It's just a design flaw. Not true since not every card uses DMA for sampling (e.g. Ultrasound).
Re: Can this monitor be used with a standard XT/AT computer?

Correct me if I'm wrong but CGA used *NTSC* composite and that looks like a PAL monitor (220V/50Hz).
Re: Opl 3 Sound Bank ?
Posted on 2019-12-10, 18:33
I'm pretty sure his question is meant the other way. He's looking for a GM sound font that sounds like an OPL3. At least that's how I understand it. No, OP has it right. A sound bank isn't a sound font. Sound font = recordings of instruments. Sound bank = description of how to synthesize …
Re: Date - Setting the date for DOSBox only

Why though, when as ripsaw says DOSBox already has an internal date command (and has had it for over 8 years).
Re: imgmount
Posted on 2019-12-05, 11:38
Are there any special reasons to imgmount from a mounted drive instead of host directory? Generally I find it's easier to keep the .iso+.cue in the same dir as the rest of the game's files and use a batch file to mount+run (and do anything else like set core/cycles) in one step. Especially if it's …

Thanks. It seems the newer a CPU is, the worse performance it has for the POPF instruction (thanks a lot, speculative execution bug mitigations) so avoiding it as much as possible is a good idea.
Re: DOSBox Feature Request Thread

You couldn't just shove frames down a pipe, you'd need some way to communicate the frame rate/sampling rate, resolution, frame delimiters... once you've done all that you've basically recreated AVI. DOSBox only records audio that goes through its mixer, if you're using an external midi device the …

Yes, the same filename shown when you use the DIR command inside DOSBox. (Or just type the first few letters of the filename and press tab to autocomplete it.)

A mounted drive only has short filenames.
