Are you able to run snes9x at fullscreen without the black border from
outside of mythgame? If so, what options are you using?

I have it running "fullscreen" but it only scales the snes screen to
double its normal size (thus 512x512 on my 640x480 screen) and has a
big black border around. If I have time I'm going to go diving into the
code to see what can be done to put more "full" in fullscreen.

Sounds good. Zsnes might a good option too (worked with *all* of
my roms, snes9x seg'd on Doom). It does real fullscreen without
much trouble and has nice a configuration gui built in.

Nope. When I said "dive into the code", I meant the code of snes9x.
AFAIK snes9x just doesn't do a real fullscreen.


The other thing about many of these emulators is that they just don't
believe in sharing the CPU. They like to sit in busy-waitloops instead
of calling a kernel sleep function. I've managed to fix this problem in
xmame, snes9x, and fceu.


In case anyone's interested in that, I had to do the following. Since
it's rather off-topic for this list, any questions should perhaps be
directed back to me instead of the list.

xmame-0.65: This one's easy. ;) Make sure the option "sleepidle" is set
to 1 in /etc/xmame/xmamerc (or wherever the config file is kept).
Alternatively, add "-sleepidle" to the command line arguments.

fceu-0.94r2: add CFLAGS += -DDSPSOUND to Makefile.unixsdl. This tells
it not to use its SDL sound output code, because that is what has a
cpu-wasting loop in it (loop waiting for SDL's output buffer to get
free space). The code could probably be fixed, but I didn't since the
dsp sound output code works fine.

snes9x-1.39: Use threadsound ("-ts" command line argument), and replace
this code in unix/unix.cpp,somewhere around line 1120:
do
{
CHECK_SOUND ();
S9xProcessEvents (FALSE);
while (gettimeofday (&now, NULL) < 0) ;
} while (timercmp(&next1, &now, >));
with this code:
struct timeval sleeptime;
struct timespec sleeptime_ns;
timersub(&next1, &now, &sleeptime);
sleeptime_ns.tv_sec = sleeptime.tv_sec;
sleeptime_ns.tv_nsec = sleeptime.tv_usec * 1000;
while(nanosleep(&sleeptime_ns, &sleeptime_ns) < 0) ;

This breaks if you don't use the threadsound option, because of the odd
way in which non-threadsound code uses a SIGALRM timer with 1/100th of
a second timeout (what a horrid use of signals! blech!) and thus
nanosleep NEVER gets to sleep because the alarm interrupts it on
*every* context switch.
