CPCEmu v3.0 (April 2025) is out.

Hybrid SymbOS DSK not load all....

The V9990 emulation is a fantastic news! I have to try it ASAP!

Doh I didn't check the new features...

I will add them to the news after my WoW raid.

Emulation doesn't start (Win11 both portable and installation). Dobbertin HD file is also missing.?

Hybrid SymbOS DSK not load all....

Hi, all. I had intended to prepare all operating systems before announcing the release officially. But it's fine this way.

I tested the SymbOS version for M4 mass storage only. Anyway, you need to increase RAM size. Have you done that?

Emulation doesn't start (Win11 both portable and installation). Dobbertin HD file is also missing.?

Thanks for the report. It's a mess with Win11. On my Win11 machines, v3.0 starts flawlessly. But I have already received a single report where it doesn't. The problem is, I can hardly find a solution as I cannot reproduce the crash. I'm trying to approach the culprit slowly. Please be patient.

And, I probably forgot to include the HD20 file, sorry. That's particularly annoying because I will have to submit another update to Google Play and the Apple app store (I'm still hoping the latter accepts CPCemu at all).

I also forgot to include index.html and favicon.ico in the Windows release. At least, this I can update without much effort.

Hybrid SymbOS DSK not load all....

I tried both 720k and 1200k versions as well as the regular disk version. All of them do boot until the start menu is visible. The screen background is black, but the start menu can be operated. However, no application can be started. Looks like a configuration issue to me.

Interestingly, if I boot from either hybrid DSK while the M4 board with the SymbOS mass storage version is enabled, the usual background image and the clock are shown and I can start applications with the mouse. However, once I open the start menu, SymbOS crashes.

[HAL6128]

It's good to see that the emulator is being developed. I'm also curious and heavily invested in the V9990 emulation.

yeah, that's a great feature for sure!
cant' wait the Linux version

[genesis8]

BTW Rainer, to answer your email no I have not yet tested the V9990 emulation, time constraint.

Anyway 2 questions with the android version :

- when the phone is in landscape mode and if the V9990 is being used, would it be possible to print the CPC screen to the left, the V9990 screen to the right ?

- lacking time to check with my phone, but if a real keyboard is connected to the phone and detected, can the the virtual keyboard stay hidden ?

Maybe you can add an option for creating a log file during boot/driving the emulator?

Interesting idea for people having large phones (=phablets?). At least, it should be possible to switch between the screens. On the other hand: Is there any software known for the CPC using both screens at all? Perhaps this feature can wait until somebody creates such software.

- lacking time to check with my phone, but if a real keyboard is connected to the phone and detected, can the the virtual keyboard stay hidden ?

You can always hide the virtual keyboard, independent of a hardware keyboard with a two-finger tap on the virtual keyboard holders (yellow and cyan areas that are highlighted if you tap outside of the keyboard).

Maybe you can add an option for creating a log file during boot/driving the emulator?

There are already two logs. One is stdout, the other one is stderr. The latter is shown in the message box if an exception occurs. Of course, you don't see that in case of a crash. So, capture both of them from the command prompt (cmd) like this (cd into the cpcemu directory first):

Code Select Expand

cpcemu.exe > log.txt 2>&1

Thanks for the hint.

This is the output of the logfile (Win11_64bit, Installation in C:\Program Files (x86)\CPCEmu3.0)

Another Log Error:

Windows 10 works fine, by the way, but only with the standard config. If additional config added it crashes....

It seems all about permissions?

[CPCBEGIN]

I try GNU/Linux versions when they will be avalaible.

[McArti0]

Maybe you have too high/low permissions for this folder?

[andycadley]

I wouldn't expect a permissions problem on an App data folder, that's typically writable by the current user. The username does appear to have a hyphen in it, which is unusual and might be an issue, but should be okay.

More likely it's a crash in something the additional config you're adding has enabled.

[HAL6128]

I've tried today the Win-Version (3.0) with Linux & Wine. It seems to work fine, also the V9990 emulation works great. I've also realized that the sdcard "live" emulation is better than under Windows. I never got access to that folder (under Win, but Linux). Transfered data from my real CPC to that folder and run it.
Nice! First emulator with V9990 support. Now a cool programming environment is available.
Next check is SymbOS with V9990.

Sure, there are plenty of ways you can run into permissions problems (typically assuming you can write to files under Program Files) but the App Data folder is specifically where applications are supposed to store configuration data and is writable by default for the current user. So unless something very weird has been done during installation I'd not expect it to be the issue.

[HAL6128]

This was my intention. Normally the "CPCEmu Installer" installs the application right into the "program(x86)" folder. But permission in such folder isn't always clear for the application if changes are necessary because you need admin-rights to do that. So I changed the folder during installation process into my user folder where everything should be set to my user-permission (allowed to do everything).
But CPCEmu always wants to create a mirrored folders system into the root drive (I don't know what the purpose of that is). And this might be the drawback??

Within the Wine environment you can see the folders which have been created / double in the C:\. But why??

The keyboard layout is also weird. I can't use the bar "|" and I have to use the virtual keyboard.
