Summary: Bug in lauching generic game epsxe
Initial Comment:
Hello,
Another bug report. I'm sorry, but I do not have enough
time to find the bugs and propose a patch for the bugs I
submit. And for the moment, I not very familiar with the
freevo code.
First, I would like to say that epsxe is running as a
standalone application (I tested it to know if I didn't
have any problem with the upgrade of my nvidia drivers).
So the bug was introduced between 1.5-rc2 and 1.5.0. I
suppose with the 1.7 revision of generic.py. The osd is
stopped, but epsxe do not start and I come back to
freevo.
I don't know if it's a problem, but the iso filename I call
for playing contains a space.
Sincerely,
Stéphane

I have the same problem with generator-svaglib in the
GENESIS mode. Some facts :
- *ALL* my other emulator are working well (XMAME, ZSNES,
VICE, FCEUltra)
- generator-svgalib IS NOT a shell at all, it is an ELF
executable
Behavior of Freevo in that case :
The poll function of childapp.py seems to detect immediately
that the new process is dead and then call the kill function
and go back to Freevo. If the poll function is deactivated in
childapp.py, then the process is not killed and everything is
fine. But i can't guess right now why this poll function work like
that.
So my guess is that the process detection (thru the poll
funcion) does not work with some application dealing with the
display.
Any ideas ??

Hi all,
OK I found the bug. It's was my fault. The problem came from
my ressource file (local_config.py). A recent changing in
childapp causes this bug for me. Now, the parameter passed
to popen2.Popen3 is a list (and not a string). My game
definition was:
GAMES_ITEMS = [ ('PlayStation
PSX', '/data/freevo/games/psx/roms',
('GENERIC', '/usr/local/psx/epsxe -nogui -loadiso', '', '',
[ 'bin','img','iso' ] )),
All was fine when childapp used string. But now with list of
args, the process was not started (poll value was 256 and
not -1). Modifying my game_item value to:
GAMES_ITEMS = [ ('PlayStation
PSX', '/data/freevo/games/psx/roms',
('GENERIC', '/usr/local/psx/epsxe', '-nogui -loadiso', '',
[ 'bin','img','iso' ] )),
solved the problem.
Sorry to disturb you with this stupid bug. You can close this
bug report.
Sorry.
Stéphane

Sorry for the delay. I wanted to test with the latest freevo
version 1.5.1, and not to disturb you with solved problem. But
in fact, I still have got the same problem.
Here is the info you wanted:
bibox:/usr/local/psx# file epsxe
epsxe: ELF 32-bit LSB executable, Intel 80386, version 1,
statically linked, corrupted section header size
bibox:/usr/local/psx# ./epsxe -v
* ePSXe emulator version 1.6.0.
And if I manually start:
bibox:/usr/local/psx# ./epsxe -nogui -
loadiso /data/freevo/games/psx/roms/Crash\ Bandicoot\ 1.img
or with '/data/freevo/games/psx/roms/Crash Bandicoot 1.img',
all works fine.
Sincerely,
Stéphane

can you post the output of file epsxe. every version i have
ever tested of epsxe had that being a script. Can you also
post the version of epsxe you are using. There were very bad
hacks in the older versions of games that only handled
spaces in rom names but used the shell version of running
the command to do it. This was bad for freevo. It had been
removed in favor of list arguments but when there are things
(like shell scripits) transforming args between freevo's
call and the invoking of the game this can break down. I
really don't want to introduce more bad hacks to support
this if i don't have to.

Hi,
I do not use any shell script to launch epsxe. I've got the
following config in my local-conf:
GAMES_ITEMS = [ ('PlayStation
PSX', '/data/freevo/games/psx/roms', ('GENERIC', '
/usr/local/psx/epsxe -nogui -loadiso ', '', '', [ 'bin','img','iso' ] )),
...
And the file epsxe is the binary file.
Also, all is running with the 1.5-rc2 (my last installed version
of freevo and with exactly the same epsxe install). Could it
could be a problem with ChildApp ? I noticed a change in
generic headers: now passing arguments with list and not
strings.

I believe this bug is related to the shell script that the
epsexe uses. I can use the visual game boy advance with
games with spaces (this uses the generic backend as well).
So i think this is a problem with the emulator. This is a
common problem with games that have shell scripts for
invoking them or for people who write shell scripts around
games to do some of their own tweeking.
