I don't think you're doing anything wrong, I just tried it, and it
gets into a kind of deadlock on the VGA initialization. CPU usage of
the emulator drops to zero... I need to look into this.

This is very strange...

The call to SDL_SetVideoMode() in bx_sdl_gui_c::dimension_update()
never returns, which means that the Cirrus' thread blocks the GUI
lock. This lock in turn blocks the CPU thread once it starts
initializing the graphics controller...

This does not happen when using the win32 gui, only with SDL, which
explains why I haven't caught it (although - of course - I really
should have).

I have no idea at this point what could cause this.

Well, at least there is a workaround - use the win32 gui instead of the
SDL gui.

Using the win32 gui *does* work - it's just that the win32 gui seems to
have even more problems
with failure to erase scrolled characters than the SDL gui does, and
seems to "lock up"
more frequently as well.  :-(

Thanks!
Dave

Hello all,

with the latest CVS, the win32 gui doesn't work for me... the emulator  
crashes before to display the graphic window.
With SDL I have same problem you got.

regards,
fausto
