!MakeMode Application

Is there a !MakeMode application that can run on RISC OS 5.27 32-bit, I’m currently running RPCEmu-.9.4a

Thank you.

It’s in the Bonus binaries download in Utilities.Developer.

David,

Thank you, I have downloaded this zip file, unzipped this using RISC OS and copy and paste the !MakeMode application, when I try and start the app, I get the following error message.

“Unknown error number 8388608”

I then click on the OK button then get another warning message from the !MakeMode application.

“Using mode definition files beyond the specification of your monitor could result in damage to the computer”

The !MakeMode will then appear on the Icon Bar on the right side.

I’m using a SAMSUNG TV as monitor, when I open the list of monitors SAMSUNG is not on the list, what option should I Select.

“Unknown error number 8388608”

It’s OK on the Titanium but not RPCEmu. How very odd!!

To make an odd size custom mode for RPCEmu I would use the cvt tool. It is probably over-kill for RPCEmu but it is easy. Even easier, in the Screen configuration tool under Monitor type, Other, Generic is an assortment of RPCEmu modes.

I’m using a SAMSUNG TV

RISC OS only has to write its screen to the host’s display, the host has to take care of the physical monitor.

(For info the MDFs, Monitor Definition Files, are text files at !Boot.Resources.Configure.Monitors.)

What I would actually like to do, is maximise the window when using RPCEmu, but guess it will depend on the size of the RISC OS screen size.

That can be done. What size is the Samsung?

e.g. A big mode to fit inside Ubuntu on a 2560×1440 display.

# 2400 x 1280
startmode
mode_name:2400 x 1280
x_res:2400
y_res:1280
pixel_rate:70000
h_timings:20,0,0,2400,0,0
v_timings:10,0,0,1280,0,0
sync_pol:0
endmode

As the MDF is only for RPCEmu and not a physical monitor some of the timings do not need to be specified, zero’s will do. Empirically that is!

n.b x-res must be a multiple of 8. For y-res a multiple of 2 suffices. Empirically!

And slightly bigger.

# 2464 x 1320
startmode
mode_name:2464 x 1320
x_res:2464
y_res:1320
pixel_rate:70000
h_timings:20,0,0,2464,0,0
v_timings:10,0,0,1320,0,0
sync_pol:0
endmode

Editing is directly on the MDF with StrongED.

David,

The SAMSUNG 32" TV that I’m using, the model number is LE32C580J1K, nit sure if this will help.

How and where would I need to copy and paste the 2 options below.

1. 2400 × 1280
   startmode
   mode_name:2400 × 1280
   x_res:2400
   y_res:1280
   pixel_rate:70000
   h_timings:20,0,0,2400,0,0
   v_timings:10,0,0,1280,0,0
   sync_pol:0
   endmode

or

1. 2464 × 1320
   startmode
   mode_name:2464 × 1320
   x_res:2464
   y_res:1320
   pixel_rate:70000
   h_timings:20,0,0,2464,0,0
   v_timings:10,0,0,1320,0,0
   sync_pol:0
   endmode

The SAMSUNG 32" TV that I’m using, the model number is LE32C580J1K

That is a full HD TV with a resolution of 1920×1080. The examples I gave are far too big.

What host is RPCEmu running on?

This could be better for a full HD display.

# 1864 x 1000
startmode
mode_name:1864 x 1000
x_res:1864
y_res:1000
pixel_rate:72000
h_timings:20,0,0,1864,0,0
v_timings:10,0,0,1000,0,0
sync_pol:0
endmode

The above is pasted into the MDF already in use as selected by Screen configuration. The file format should be self explanatory. I usually put entries in x-res order, that may not matter much but at least it’s easier to find again later. Having edited, and saved,the MDF it has to be reloaded by the Screen configuration tool using the Set button. The new resolution should then be present in the Display Manager on the right of the iconbar. Don’t set the new resolution in Screen configuration until new resolution is satisfactory as otherwise RPCEmu would boot into an unsatisfactory mode.

HTH.

David,

Not sure how to do quotes here on the forum, so just copy and paste.

When I select the correct folder HostFS:HostFS.$.!Boot.Resources.Configure.Monitors.Samsung there are 6 text files in this folder, here is the list below.

760BF
930BF
Samsung-172V
Samsung-760BF
Samsung-930BF
SM172V

Would I need to create another text file or add this, want to make sure it’s in the correct location and once done how do I then go and select a new screensize.

I only have three files in the Samsung folder. None of them are of any use, they for lower resolution monitors probably from the last century. I would use Other.Generic.

Since you’re using RPCEmu, don’t mess about with MakeModes and MDFs. Just install AnyMode and then select the display size you need. With AnyMode installed, it should be possible to just enter

X2400 Y1280 C16M

(or whatever you’re after) into the Mode box on the Display Manager’s iconbar menu to try things out.
