RPCEmu Os X 10.14.06

Hello everybody

I wanted to test rpcemu under Mac Os 10.14.06 .. and there it is the drama …
the mouse pointer moves only to make a selection, very small application window is impossible to size. Already if the mouse pointer wanted to move.

Thank you.

Ensure that ‘Reduce CPU Usage’ is not ticked in Settings, that should get mouse clicks working consistently.

it is not activate

What version of RPCEmu is this?

0.8.14

That is a bit old now, 0.9.1 should be better.

very small application window is impossible to size

The window will be fixed at the size of the current RISC OS screen mode.

To change this, use the Display Manager: the monitor towards the right-hand end of the iconbar. Depending on how things ship these days, you might need to fiddle with the monitor definition in order to get a useful range of modes.

I was wrong on the way to the rom (0.9.1), and impossible even by deleting it that it re-asks me for a new way and I do not know where it saves on the hard drive.

The 0.9.1 download is just the application. Also required is the RPCEmu data structure that contains the folders for hosts, roms etc.. This data structure is in the Linux Source Code download. Unzip that to somewhere convenient then select that location when the rpcemu app starts up for the first time. The RISC OS 5 set up is here. Note that the 0.9.1 app does not support networking.

Might be useful to update this document to make the information readily available to all concerned.

he absolutely wants to look for the rom to a path on the hard drive which is now invalid, so when I run the program I have no control over anything

I found you have to go through the terminal .. painful ..

Now “risocs-3.71.rom” it does not recognize it, gray it out in the selection window …

Finally it works .. if we can say :-) I am in supervisor mode with an order pending but why ???

I’m glad it is working, but supervisor mode should not be needed. I have the dmg in my user space but it should be OK in Applications. I am on Catalina and that does require some security permissions to be set, it is easy to do and it does ask.

I was about to post the following, it might be helpful.

Starting the app with the cmd key pressed and held as the app starts should offer the “Choose Data Directory” dialogue.

If really stuck then delete /Users/imac/Library/Preferences/org.marutan.rpcemu.plist

on the command prompt I have access to basic but not to the office

Luc, have you downloaded the source code? You need this as it contains files and folders that RPCEmu needs to run. They are not included in the 0.9.1 you downloaded as it is not an official build and the Mac keyboard patches are not yet part of the source code.

Download the file here: http://www.marutan.net/rpcemu/0.9.1/rpcemu-0.9.1.tar.gz

Unzip it (double-click on it) and you will see a folder named “rpcemu-0.9.1”. Inside this will be another folder, called “roms”. Copy the RISC OS ROM you want to use into this “roms” folder

Now run RPCEmu with ALT held down. It will ask you to choose a folder. When you do this, you need to select the “rpcemu-0.9.1” folder – the one that contains “hostfs”, “netroms”, “poduleroms” and so on. If you choose the wrong folder, it will not work.

I have not seen this before so I gave the above instructions a go. While not strictly on topic I thought I would recount my experience.

I copied my hostfs contents from Virtual Acorn 4.39 & 4.39 ROMS from my real RISC PC. I had to comment out the following line

| RMEnsure VProtect 3.80 RMLoad Boot:Utils.VProtect

from !Boot.Utils.BootRun

to get the desktop to start.

After that a few apps balked but it looked ok.

I have Sierra 10.12.6 on a 27" 2017 iMac.

I could not get RISC OS anywhere near the native resolution of my screen I guess a RPC didn’t run to 43M of VRAM to do 5120×2880 at 24bpp.

It took a while to work out that FUNCTION+CTRL+RIGHT ARROW is the same as CTRL+END to get the host mouse back if you have the small Apple keyboard. I also found that a two finger swipe left to the Dashboard, followed by moving the mouse to somewhere that would not be over the RISC OS window when you swipe back works.

I don’t exactly know how VA does its networking but something along the line of a HostSockets module might be an alternative to the mucking about with NAT and stuff often needed in our emulators.

I don’t think its going to replace my Pi with 5.27 but it did remind me I would love the RO4 series !draw and !paint on 5.

OS4.39 limits its video bandwidth which is not necessary for use on RPCEmu. Just add a zero to the values in this file Boot.Choices.Hardware.Disabled.Boot.PreDesk.Configure.!Run.

RPCEmu has 8MB VRAM with a maximum resolution at 16M colours of 1920×1080. 2560×1440 full screen is at 32 thousand colours.

David,
thank you for that. I made the above change and that caused booting to abort until I upgraded the selected cpu to strong arm.

The best that I can get is 1360×768 in 32k. This seems to be because the mac port won’t give more than 2M VRAM. I tried editing this in the config file rpc.cfg, where I made vram_size=8 but the UI seems to overwrite this every time with vram_size=2

Alan

This seems to be because the mac port won’t give more than 2M VRAM.

What RPCEmu version is in use, looking at this thread there seems to be some risk of that being 0.9.1.

I have RPCEmu 0.9.3 running OS4.39 in 8MB VRAM on a 10.15.5 iMac. There is a release here. This is my startup log.

The emulator attempts to patch the OS to support 8MB VRAM on startup. If it is, you should see a message starting with “romload: ROM patch applied”, followed by the name the OS – David’s log includes this about 2/3rds of the way down:

romload: ROM patch applied: 8MB VRAM RISC OS 4.39

From the source, this should work with 3.5, 3.6, 3.70, 3.71, 4.02, 4.04, 4.29, 4.33, 4.37, 4.39 and 6.02. It works by trying to match a piece of data at a particular offset in the ROM, so if your ROM is non-standard in any way, it may not work.

but the UI seems to overwrite this every time with vram_size=2

It looks like that’s normal – it’ll write “2” for a non-zero VRAM setting when saving the settings. When it loads the settings, it treats any non-zero value (or a missing value) as 8 MB. In addition, if you’re emulating an A7000 series, VRAM is set to zero, whilst it’s set to 4 MB for the Phoebe.

Yes this thread had led me to 0.9.1 I have now upgraded it to 0.9.3.

I don’t see a log line saying rom patch applied:

config_load: vram_size = “2”
romload: Loaded ‘RPCRO439’ 4194304 bytes
romload: Total ROM size 4 MB
plt_sound: qt5 Audio Device: Built-in Output

I repeted the *save and the copy via LanMan89 to my Nas and then to my mac but I got the same md5sum

Alans-iMac:RPCemu alan$ md5 roms/RPCRO439
MD5 (roms/RPCRO439) = 70223126095c1c88be6cd393dc30d72c

I don’t have a tool on the RPC to check that at the source, I am not sure if I have another RPC with 4.39, I recently gave a way most of my pile of them.

I do have VA though so I have saved the rom from that and got a different md5sum:

Alans-iMac:RPCemu alan$ md5 vaRo439
MD5 (vaRo439) = dc3723b9e5a3eba6e81c6fef29122828

This wasn’t identified for a rom patch but appears to not need it. It gave better screen modes. I would be a bit worried with the VA rom that there may be other changes which may lead to unexpected behaviour so I will have a look at the source to 0.9.3 when I get a moment and see if I can see why its not identifying my RO439 rom image.

Thank you for the help
Alan

I have now upgraded it to 0.9.3.

The good news about 0.9.3 is that NAT networking “just works”.

I would be a bit worried with the VA rom that there may be other changes which may lead to unexpected behaviour

I used a RiscPC ROM image from the Select scheme.

Added

imac@iMacPro roms % md5 3i4
MD5 (3i4) = 18778b10e86f642589300650f115929b

I think the ROM supplied with VA is unique to VA.
