Sega model 3 #segamodel3

@red_trev They're running it from the desktop so they already have a window system it can use. If we're running from the command line you need xinit to give it a window system. You also need to pass it the full path to the rom (eg. /home/pi/RetroPie/roms/model3/dirtdvls.zip)

not sure why the games.xml can't be parsed. I don't know if its the screenshot but it looks like 'Comfig rather than 'Config'

I can't believe i missed out on the whole PPC underclocking angle! That's quite an exciting easy update

The method above (video) seems to be perfect to fix the exit buttons problem and more. I'll replace the Keyboard buttons combos for UI settings by gamepad buttons combos (and more save buttons). After that. I'll generate the Makefile and build with the following

ln -s Makefiles/Makefile.UNIX Makefile .

I'm not sure about his 3d setup. Have you an opinion about that. Does he make any tuning errors on the video for 3d?

@mechafatnick got it working , and yes there was a typo ...

first i Filezilla'd the ROM into the same folder as the supermodel emulator (opt/retropie/emulators/supermodel/bin)

then via cmd line i cd to
/opt/retropie/emulators/supermodel/bin

then i ran the command
./supermodel -legacy3d -sound-volume=50 -music-volume=60 -no-vsync -no-throttle -no-dsb -res=1000,768 ./fvipers2.zip

no need for xinit as you can see ....

game loaded, all controlls worked, video filled the screen of my 28 inch tv perfectly, though it did seem to slow down the game slightly ....

i will have a play around with the settings & when i find what works the best ill report back ;)

@dteam let me know how you get on! 😁 I've already added a couple of options for underclocking and got a couple of titles running better.

I know, what you have done work very well. Honnestly, It's awesome! That's why I would like to continue to use it. Can you provide a link with what you have done, but not compiled with Makefiles. I would like to get what you have done but modify inputs.cpp

like this :

uiExit             = AddSwitchInput("UIExit",             "Exit UI",               GAME_INPUT_UI, "KEY_ESCAPE,JOY1_BUTTON1+JOY1_BUTTON10");

or

uiExit             = AddSwitchInput("UIExit",             "Exit UI",               GAME_INPUT_UI, "JOY1_BUTTON1+JOY1_BUTTON10");

and after that use Makefiles

Controls
@dteam Yep that'll work, but why stop there? If you change the system controls to common controls you can map all of them in supermodel.ini. This morning I edited inputs.cpp to comment out the lines corresponding to exit/pause/screenshot/save states and then add these lines to the common controls section :

uiExit             = AddSwitchInput("UIExit",   "Exit UI",   Game::INPUT_COMMON, "NONE");
uiPause            = AddSwitchInput("UIPause",  "Pause",     Game::INPUT_COMMON, "NONE");
uiScreenshot       = AddSwitchInput("UIScreenShot",	 "Screenshot", Game::INPUT_COMMON, "NONE");
uiSaveState        = AddSwitchInput("UISaveState",   "Save State",    Game::INPUT_COMMON, "NONE");
uiLoadState        = AddSwitchInput("UILoadState",   "Load State",    Game::INPUT_UI, "NONE");

Build it (you can follow the instructions in the video) You can then map all these functions in supermodel.ini:

InputUIExit = KEY_ESCAPE,JOY1_BUTTON10+JOY1_BUTTON9
InputUIPause = JOY1_BUTTON9+JOY1_BUTTON1
InputUIScreenShot =  JOY1_BUTTON9+JOY1_BUTTON5
InputUISaveState = JOY1_BUTTON9+JOY1_BUTTON7
InputUILoadState = JOY1_BUTTON9+JOY1_BUTTON8

Save states wont work for me, but the rest work a treat :D

Performance
In terms of performance, i originally completely the section about underclocking the PPC. When running games, the real CPU is occasionally idle while its waiting for memory transfers to happen, so why waste our precious PI resources emulating a CPU that isn't doing anything? Underclocking the CPU frees up Pi resources to run the rest of the emulation better, but underclocking it too far means that our emulated CPU can no longer run the game (in virtual fighter 3, for example, i had Kage literally come apart at the seams :D)

What i did was edit /opt/retropie/configs/model3/emulators.cfg and clone the entry multiple times, with different clock rates from 48-25. This allows us to find the optimum for any given game and save it as that rom's custom emulator in emulation station:

Supermodel-normal = "XINIT:/opt/retropie/emulators/supermodel/bin/supermodel -game-xml-file=/opt/retropie/emulators/supermodel/bin/Config/Games.xml -legacy3d -sound-volume=50 -music-volume=60 -no-vsync -no-throttle -no-dsb -res=496,384 %ROM%"
Supermodel-45-hz-PPC-Underclock = "XINIT:/opt/retropie/emulators/supermodel/bin/supermodel -game-xml-file=/opt/retropie/emulators/supermodel/bin/Config/Games.xml -ppc-frequency=45 -legacy3d -sound-volume=50 -music-volume=60 -no-vsync -no-throttle -no-dsb -res=496,384 %ROM%"

Awsome!! Is It updated on your download link? With what you have done, This could work like retroarch hotkeys. For savestate is It a folder problem? For Supermodel.ini, the emulator set control in the emulator folder but read in home/pi/Config that’s why I have use a symlink instead of a new supermodel.ini file (see my post about that above). For savestate it’s maybe the same. Maybe It create it in one place and read in another place.

With dose changes, could it be on the official experimental list in retropie ?

For the fullscreen problem, i’ll try to found a solution for that, but I’m not an expert for that 😁

mechafatnick

@dteam I didn't even think about the possibility of it actually ending up as an experimenal emulator. I just wanted to run some arcade-perfect VF3 :D

I've amended the zips on my guide and also put my amends to the sourcecode up on github for anyone who's interested:

@mechafatnick

I followed you guides and installed it on my old x86 laptop, as I am on a holiday.
(works slow, as aspected on my laptop, but now I know it can work !)

Curious how this will indeed work on the pi4.

Your quite far in "development" now.
Are you going to try and make a module-script for it ?

It works very well on a Pi4. The games look a little bit like Naomi or Atomiswave with lr-Flycast.

@mechafatnick said in Sega model 3 #segamodel3:

@red_trev ahh remember you have two factors in play - the size of the screen the emulator is rendering and then the window the emulator is placed in in the pi.

It sounds like the emulator window is bigger as per the file but the actual window the emulator is being placed into isn't. You should be able to solve it by launching a game from emulation station, entering the configuration menu then changing the default video mode for super model (i use 87-46 myself.)

the one in /home/config is the one you need to edit. The arguments you feed to the editor will take priority so if you want to mess with the resolutions per game you'll need to dump those.

Remember though that the Pi is definitely not the optimum hardware for Model 3 emulation so i wouldn't push the resolution too far!

I have tried everything and cannot get it to display full screen via Emulation Station, it is still stuck in a small box & zoomed in to bottom left corner:

I have tried changing video modes in pre launch menu & Raspi Config menu itself but same result regardless of any change

When I open a game via cmd line without XINIT it does show fullscreen but with slowdown

Here is the contents of the emulators.cfg file:

supermodelHighRes = "XINIT:/opt/retropie/emulators/supermodel/bin/supermodel -game-xml-file=/opt/retropie/emulators/supermodel/bin/Config/Games.xml -legacy3d -sound-volume=50 -music-volume=80 -no-vsync -no-throttle -no-dsb -res=1024,755 %ROM%"

Hi

When i'm using your old /opt/retropie/emulators/supermodel/bin/supermodel, It run well, but when I run your new file. I get this message in Supermodel.log

[Error] OpenGL initialization failed: Unknown error

[Info]  Program terminated due to an error.

and in shm/runcommand.log this message

Executing (via xinit): /opt/retropie/emulators/supermodel/bin/supermodel -game-xml-file=/opt/retropie/emulators/supermodel/bin/Config/Games.xml -legacy3d -sound-volume=50 -music-volume=60 -no-vsync -no-throttle -no-dsb -res=496,384 /home/pi/RetroPie/roms/model3/spikeout.zip

Could it be your new changes with R3DShaderTriangles.h?

@red_trev What video mode is 52-20, sorry?

mechafatnick

@dteam That's surprising! try:

sudo apt-get install libsdl2-net-dev

It works with that. Thanks.
UI buttons settings work also with gamepads !!! Fantastic

@red_trev what happens when you ditch xinit and lower the emulator Res to 496 *384?

Red_Trev

@mechafatnick said in Sega model 3 #segamodel3:

@red_trev what happens when you ditch xinit and lower the emulator Res to 496 *384?

via command line it opens in a small window, should I try that via emulators.cfg ?

mechafatnick

@red_trev yeah lower the resolution in emulators.cfg, keep it for run command :)

Red_Trev

@mechafatnick said in Sega model 3 #segamodel3:

@red_trev yeah lower the resolution in emulators.cfg, keep it for run command :)

but the whole point is not playing in a box a quarter of the screen size... is there any method to remove this limitation? I can see the video is increased but it's focused on bottom left corner, why is it doing this? is it XINIT causing it ?
