Hi, for some reason the program can't determine the USERPROFILE environment variable, or HOMEDRIVE + HOMEPATH.

The log file should be here: C:\Users\hrist\AppData\Local\ibmulator\log.txt
Can you please verify if it's there?

No, it is NOT. I've already told you that. I searched the entire hard drive and the log file does not exist although message says it was wriiten..somewhere.......

Does this has to do with using greek and english language in Windows 10?

I've noticed that many folders like Icons or Music even Users folder are displayed in greek.

Does this makes the program to be confused?

Nevertheless, when I first run ibmulator.exe it creates the ibmulator.ini file, as expected!!!!

But the log file can not be created!

by the way, if I make a fresh install of Ubuntu 14.04.6, will I be able to run 0.8 version?

I insist about Linux because as I've said, the problem with Windows looks like.....it's unbeatable!
And I am not willing of re-installing Windows.....

Thank you for your feedback, Chris. Looking at the source code and given your description of the issue, it appears to be a problem with the handling of files and/or directories, maybe caused by a non-latin charset.

Can you look for the presence of the "capture" folder inside C:\Users\hrist\AppData\Local\ibmulator ? This will help me narrow the search field.

by the way, if I make a fresh install of Ubuntu 14.04.6, will I be able to run 0.8 version?

You really want to use this emulator, don't you? :)

The odds are definitely better with Ubuntu 14 than with any other distros. When I compiled that version I tried to create a portable binary but at least one library was missing from the package, libnettle4, if memory serves.
Try to launch the bin/ibmulator program in a terminal and see what happens....
Don't try inside a virtual machine though, because you need a working OpenGL system.

It could still be a problem with the ini file. Can you attach it here?

It doesn't create a "capture" directory either!!!!! :(((

Yes I want to use it for one and only reason. Because it is the only DOS emulator that emulates the sound of disk / hard drive when loading!!!!!!! Only Amiga emulator could do that......

I can't see anything obviously wrong in that ini file.
(FYI you can specify the rom name relative to the C:\Users\hrist\AppData\Local\ibmulator\ directory, so simply romset=FC0000.BIN)

Can you try to create the "C:\Users\hrist\AppData\Local\ibmulator\capture" directory and see what happens?

Yes I want to use it for one and only reason. Because it is the only DOS emulator that emulates the sound of disk / hard drive when loading!!!!!!! Only Amiga emulator could do that......

Yes, I think all the various noises and leds add a lot to the experience.

I did create a directory capture and nothing happened.

It's like ibmulator directory is not recognised at all.........

I give up :(

No please don't give up! :(
Give me a couple of days, I'll prepare a special version of ibmulator.exe to get better diagnostic messages!

Please try this executable:
ibmulator_for_chris.zip
Put it inside the bin directory, and use it instead of ibmulator.exe
It should tell you what goes wrong before the creation of the log file.

I've managed to get it work on Ubuntu 14.04 :)
I would prefer the newer version for the Windows, though.....
Okay, I will give it a shot tomorrow morning.

But now, I'm 100% sure that problem derives from the messed up greek/english language of the hard drive.

What do you think doc? :)

Okay, problem solved!

Since error message said that assets were unable to be found, that trigged me to move the whole "IBM" folder into C:\ where no greek names were used for folders and subfolders.

And.....out of a sudden......problem was eliminated!!!

IBMulator run like a charm!

Thank you VERY-VERY MUCH for the help!!!!! :)

Now.......let's play some "The Secret of Monkey Island"........

Thank you Chris, this will help the development of IBMulator. I'll try to fix the problem, or at the very least I'll have some suggestion to give to other users who might encounter the same issue....
Enjoy Monkey Island! ;)

Now, I have 3 questions:

1. What kind of shaders can I use? What kind of extension? i.e. .glsl is valid? .fx is valid?
2. In order to play Monkey Island, do I have to create an .img file with all the files of the game?
3. I use the 2121 BIOS but the 4-quad GUI doesn't show up like in 2011 BIOS. Instead, a "Non system-disk or disk error. Press Enter" appears after memory test. What do I have to do in order to use the Hard Drive for booting?

Now, I have 3 questions:
