[Linux][lamachin] Black screen when launching L.A. Machineguns
Hello to everybody,
L.A. Machineguns is correctly booted, but all I can see is a black screen. This bug has not already been posted on Github. There is no trace of it neither in the FAQ (https://www.supermodel3.com/FAQ.html) nor in the forum (https://www.supermodel3.com/Forum/). This problem is always occurring, it is not an intermittent bug.
This is the output of my Linux shell, there are no errors:
./supermodel lamachin.zip Supermodel: A Sega Model 3 Arcade Emulator (Version 0.3a-WIP) Copyright 2003-2023 by The Supermodel Team GPU info: 4.6 (Core Profile) Mesa 24.0.5-1ubuntu1 (core profile)
Title: L.A. Machineguns: Rage of the Machines (Japan)
ROM Set: lamachin
Developer: Sega
Year: 1998
Stepping: 2.1
Extra Hardware: Security Board
I am using Ubuntu 24.04 LTS, with gcc (Ubuntu 13.2.0-23ubuntu4) 13.2.0 and libglu1-mesa-dev installed. Ocean Hunter, Star Wars Trilogy, The Lost World and Fighting Vipers 2 do not have this problem. Any help is greatly appreciated. I am available for any additional information.
Are you giving up already?

Hello ioamero, thanks for the information.
I executed ./supermodel -print-gl-info, here are my graphical specifications:
Supermodel: A Sega Model 3 Arcade Emulator (Version 0.3a-WIP) Copyright 2003-2023 by The Supermodel Team GPU info: 4.6 (Compatibility Profile) Mesa 24.0.5-1ubuntu1 (compatability profile)
OpenGL information:
Vendor : Intel Renderer : Mesa Intel(R) Graphics (ADL GT2) Version : 4.6 (Compatibility Profile) Mesa 24.0.5-1ubuntu1 Shading Language Version : 4.60 Maximum Vertex Array Size: 3000 vertices Maximum Texture Size : 16384 texels Maximum Vertex Attributes: 16 Maximum Vertex Uniforms : 16384 Maximum Texture Img Units: 32
My Shading Language Version is 4.60, so it's ok to run the emulator https://www.supermodel3.com/FAQ.html.
I tried ./supermodel lamachin.zip -frag-shader=Fragment_NoSpotlight.glsl as well, but nothing happens https://www.supermodel3.com/AdvancedUsage.html#Shaders
libsdl2-dev and libsdl2-2.0-0 were already installed. I installed your sdl image package list (libjpeg-dev, libwebp-dev, libtiff5-dev, libsdl2-image-dev, libsdl2-image-2.0-0) but there is always the black screen instead of the game's attract mode.
Try with this two options ./supermodel -new3d -quad-rendering lamachin.zip also your rom might be outdated.
Hi ioamero,
I tried your command, as well as ./supermodel -legacy3d -quad-rendering lamachin.zip, but we should find another solution. I think it's really a bug because I have this problem only with L.A. Machineguns. I will test my rom on a Windows system, then I will let you know the result ;)
Ok, I can confirm to you that my rom is working in Windows 11, so it's just a problem related to the Linux version of the emulator.
Try reducing the resolution to something extremely small 256x256 windowed mode for example. See if it boots
Thanks for the suggestion. Although I erased the NVRAM file before booting, the game gave me the same black screen. Even the low resolution boot did not work.
Hello to everybody! I have just installed the new 0.3a-WIP version and LA Machineguns is working :)
