I tested the last scummvm version on W95 OSR2.1 and it doesnt work because some missing dll files. I get them from Windows 98 system folder and then dont work because it can run opengl renderer under windows 95. After modifying the scummvm.ini file in c:/windows and specify supereagle renderer it manged to work. The problem now is that is not possible to get fullscreen on games. I tryed every graphics option in scummvm menu.

I tryed it also in Windows 98 SE and the issue is the same. It works with opengl but can't set fullscreen mode. Only can play windowed games.

Anyone can help me with this?

Maybe an older version of scummvm will work perfectly in 95 and 98? Which one?

Thanks

I made this note awhile back:

If ScummVM unable to launch on Windows 2000 then likely an OpenGL incompatibility.
This issue occurred with ScummVM 2.7.0 on Windows 2000 in Vmware
Launch with scummvm -g blah

Try 2.5.1 first and if that works then try newer versions, if not then try older.

2.7.0 did not work
2.1.0 did work perfectly but only in w98 (w95 still not capable of launching fullscreen)
1.8.1 was not able to detect spanish blade runner

So I'm stuck now on 2.1.0 but it is not fullscreen on W95.

Which version of 95?
Do you have the the ogl package as well as ogl drivers installed? Run dependency walker against scummvm

OSR 2.1

It's a clean install, simply with directx, graphics card and motherboard drivers. Also I don't know what is ogl drivers and dependency walker.

Make sure opengl32.dll exists in the Windows folder or some subfolder (probably system), if not you'll need to install the package for it. "Opengl95" which is OpenGL 1.1 for Windows 95.
It's possible that newer versions of ScummVM require OpenGL 1.2 so make sure your graphics card OGL ICD supports it.
Dependency Walker is a free program you can download to run against problems to see what issues they may have such as missing or incorrect dependencies.
