Just tried by removing the symlink and copying my Documents/openMSX into .openMSX and the result is the same. Also openMSX is able to create files into .openMSX/persistent folder so seems something else then my previous assumption.

Tried the same thing on Windows. The command succeeds but the file hd.dsk is created in the folder where openMSX.exe is located (C:\Program Files\openMSX.dev in my case). So probably this command uses the wrong folder and should use the data folder as prefix. On Mac this would indeed be (somewhere) in the /Applications/openMSX.app folder which is not writable.

I always specify an absolute path (e.g. diskmanipulator create /tmp/vgmplay.dsk 32M).

Yeah that works, still if no path is specified the default should be (somewhere in) the data directory. Not the program directory. At least imho.

Yeah, it's a known issue, see e.g. https://github.com/openMSX/openMSX/issues/1008 and tickets mentioned therein.

Regarding the stuttering in the new release. I made a following test (on Windows):
1. Start openmsx 60hz + game + full screen
2. Gameplay is jerky
3. set maxframeskip to 100
4. go full speed with F9 for a while
5. return to normal speed
6. display is smooth + occassional tearing

anyone else seeing this ?

mzoran: some of these things changed in openMSX 16.0:
1. F9 doesn't go to maximum speed, but to 'fastforward' mode. The actual speed is in a new setting and it's about 20x normal speed.
2. You don't need to set maxframeskip to 100 anymore to make use of high speed

For such a test please also tell us:
- which renderer are you using? (SDL or SDLGL-PP (default))
- which MSX model and software (is the MSX on 50 or 60 Hz mode)
- which setting do you have for vsync? (on (default) or off)
- how does it compare to older versions of openMSX, specifically 0.15.0 (previous release)?

So I am testing on my laptop with Win10 and my own game
https://www.msxdev.org/2020/04/28/msxdev20-03-subcommander/
jerkiness and tearing can be clearly seen on moving ships.

I do use all defaults as you list: SDL-PP, vsync on, machine c-bios_msx_jp. Resolution is full HD 1920x1080.

It seems this trick with F9 in full screen mode only works with the new release. When I tried it with
openmsx-0.15.0-7-g8f7a14971-windows-vc-x64 it didn't help

Let me re-iterate that just going to WebMSX version, selecting a MSX1 Japan, going full screen smoothness is immediately visible, no need for tricks

Are you able at least to try and see how it behaves on both emulators on your computers ? If it works well it must be drivers/monitor combination

Thanks
