pcem4crt - pcem mod for crt v17

[psakhis]

Hi every one,

I patched this great PC emulator for my arcade cabinet and i'm very happy with it.

New features:
   - 320x200@60hz vga timmings (no more 320x200@70hz are needed, more smooth for crt purposes running without slowdowns at full 100%)
   - autoswitch resolutions in fullscreen (borderless / exclusive modes). I strongly recommend fullscreen exclusive mode

Future changes:
   - opengl suport for linux (now only direct3d)
 
Download Link: pcem4crt download file
GITHUB Link: https://github.com/psakhis/pcem4crt

Recommendations for automation:
   - Install software inside hdd vhd/img files (one for every different configuration 486, xms, pentium, ems, ...)
   - Configure different machines with these img files
   - Every autoexec.bat of this machines run a floppy a:\start.bat  (360kb img disk file)
   - Every floppy img starts a different software from hdd vhd/img file, configure this floppy img at start emulator.

Hey !

Patched with ? May I suggest you take a look at the switchres library that Calamity has exported from GM ? this would make it portable to Linux

[psakhis]

I used libswitchres, it's really easy with wrapper opening .dll/so. Really good @Calamity works 

I needed to modify a lot of pcem src files because BITMAP variable caused conflicts window.h, i should prepare patch files for the future...

All modifications are portable to the linux but i don't have installed any for test. All the src files are included on download file.

Emulator works really really well, just incredible DOS games with CRT.

then give a link to the source and I'll see how linux behaves

[psakhis]

I modified "wx-sdl2-display-win.c", i think "wx-sdl2-display.c" it's the same for linux version. You can see in "src folder" of 7z file.

I think there aren't more files affected for windows vs linux.
When i detected a resolution change i launch an even to SDL for switchres

if (event.window.event == SDL_WINDOWEVENT_MAXIMIZED) {                       
                         if (video_fullscreen_mode == 0) {    
                            if (vid_resize!=0) //patch
                              vid_resize=0;                               
                                pclog("Maximized Switchres %i x %i!!!\n", event.window.data1,event.window.data2);     
                                SetMenu(hwnd, menu);
                      SDL_SetWindowFullscreen(window, 0);
                      SDL_SetWindowSize(window, remembered_rect.w, remembered_rect.h);
                      SDL_SetWindowPosition(window, remembered_rect.x, remembered_rect.y);
                      SDL_WarpMouseGlobal(remembered_mouse_x, remembered_mouse_y);
                      device_force_redraw();                                                       
                                update_switchres(event.window.data1,event.window.data2);
                                window_doinputgrab = 1;                                
                                window_dofullscreen = 1;           
                         }   
                          if (video_fullscreen_mode != 0) {  //needs vid_resize = 1 or 2     
                             if (vid_resize==0) //patch
                              vid_resize=1;                                                                       
                             pclog("Exclusive Switchres %i x %i!!!\n", event.window.data1,event.window.data2);                                            
                                update_switchres(event.window.data1,event.window.data2);                               
                                display_resize(event.window.data1,event.window.data2);                                   
                                window_dofullscreen = 1;     
                               
                         }

Just saw your github repo. If you allow me to share my opinion : you shouldn't embed the switchres code. If there is any update (and there will), you won't benefite from them. Eventually use a github submodule.

But I understood you used the shared library + API, right ? You didn't instanciate a switchres_manager object ?

Anyway, you can make + make install switchres. On linux at least, it will put the required files at their good place, and even drop a pgk-config .pc file. So it's a good way to get things done easily

[psakhis]

I try to do that, i'm a github noob (15 years without programming xD).

Effectively i use API with wrapper, so only needs a .dll/.so switchres file.


_{..
+void svga_switchres_init() {
+const char* err_msg;
+
+   pclog("Switchres %s.\n", LIBSWR);
+
+   // Load the lib
+   dlp = OPENLIB(LIBSWR);
..}

Hi psakhis,

It's a very nice surprise that you've implemented libswitchres in this emulator, thank you!
