https://www.youtube.com/watch?v=I8_z_CI37JE DOSBox has it right on :-) Very interesting. The sound output on my speakers (iMac) sounds slightly “rougher” but almost identical to that recording. However, I do hear a high pitched ring in my recording that is not in the video - does anyone else hear …

Tandy sound emulation quality - issues with Skate or Die

Generally, I find that the Tandy sound emulation in DOSBox is very good, although I have to admit that it has been many many years since I heard the output from a real Tandy PC. However, in Skate or Die, something has always sounded off, and so I got around to testing the game in PCem (v17) as a …

After all that, I only just realized that control-esc does work in Windows 95 and 98, so I can still use that to access the task bar in most instances (and hence swap the images using the Virtual Clone Drive menu bar icon). Not as quick or user-friendly as a key combination, but it gets the job …

DOSBox does not support Win9X. Yes, that is why I wrote a whole paragraph in my first post to try to head off such a comment. ;-) Thanks, I will try out Daemon Tools/ Magicdisc to see if that offers better functionality than Virtual Clone Drive. I realize most games are fine with reading from …

For some reason I thought there was floppy swapping ability with a hotkey for similar reasons, any way to abuse that? Or am I thinking of a different em? That features has been available in DOSBox SVN for a while, though it is not in the standard DOSBox release. Either way, I doubt it would help …

I am not asking here because I am demanding or expecting there to be a solution. For my own curiosity …

OK, however just for the record, my machine type is set to svga_s3. I guessed that was the case because your screenshots with aspect=true already have the "proper 4:3 ratio" you asked for, so I'm trying to explain that for the purpose of aspect correction the aspect ratio refers to the display area …

To be more specific, there is a known issue with the aspect correction of 350-line modes when using the machine=ega setting, which includes text modes due to the 14-line font. However, I'm not aware of any compelling reason to use the EGA machine type for original SimCity. OK, however just for the …

Yes, it is the EGA high resolution mode. That must be it then.. the non-standard resolution does not work properly with the aspect ratio correction, which is designed for the standard 640x and 320x resolutions? I expect there is no way to get around that then, apart from playing it in the lower …

I have a question about the correct aspect ratio setting to use for the original DOS version of SimCity running in DOSBox. I thought that using "aspect=true" provides the most authentic experience, given that it attempts to scale the screen to the 4:3 ratio of old CRT monitors. I use this for almost …

The non-recursive page fault handling was added to the dynamic_x86 core in DOSBox-X 0.83.10 by a contributor, and according to his description this makes the dynamic x86 core more friendly with Windows 9x.

All the stuff DOSBox-X added to the dynamic_x86 core to "handle page faults" is mostly nothing but a huge slowdown. Nearly all memory accesses performed by that core (dyn_read_byte/write_byte/read_word/write_word) already handle faults correctly and the remaining opcodes that can cause problems ( …

As you mentioned earlier DOSBox-X performed slower than SVN for your games in macOS, unfortunately. There are many libraries used by DOSBox-X, but I am sure the performance issue has nothing to do with this patch. You can take as many libraries or features from DOSBox ECE or DOSBox-X into your own …
