problem with ePSXe in Linux

[Shadow-5471]

Hi to all! I have a big problem about my ePSXe in Linux (Ubuntu Gutsy Gibbon). The executable file just doesn't start. I've tried to launch it by terminal, but the output is:

andrea@andrea-desktop:~/Downloads/epsxe160lin$ sh epsxe
epsxe: 1: ELF


Linux
��44: not found
epsxe: 2: 1�X���T�P���RQ��: not found
epsxe: 4: Syntax error: "(" unexpected
andrea@andrea-desktop:~/Downloads/epsxe160lin$

Note that the strange simbols are in my terminal too.

please help me! And sorry for my bad english...

That problem is related to 2.6.22 kernel.
In order to run ePSXe on Gutsy Gibbon you will have to compile and install newer kernel.

Here is how to do that (I used the latest stable kernel 2.6.23.1):
Open Terminal and enter:

sudo passwd root
su

sudo apt-get update
sudo apt-get install kernel-package libncurses5-dev fakeroot wget bzip2

cd /usr/src
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.23.1.tar.bz2

sudo tar xjf linux-2.6.23.1.tar.bz2
sudo ln -s linux-2.6.23.1 linux-2.6.23.1
cd /usr/src/linux-2.6.23.1

cp /boot/config-`uname -r` ./.config

make menuconfig

In kernel config menu go to "Load an Alternate Configuration File" and enter .config.
Go to Processor type and features, select Processor Family and choose the one you have.
When you are done just save and exit.

Now enter this:

make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=-custom kernel_image kernel_headers

cd /usr/src
ls -l

Now go to /usr/src and run these packages:
linux-image-2.6.18.1-custom_2.6.23.1-custom-10.00.Custom_i386.deb
linux-headers-2.6.18.1-custom_2.6.23.1-custom-10.00.Custom_i386.deb

And that's it, reboot the machine now.
When the GRUB is loading press Esc and select a new kernel.

Thx! I'm downloading the kernel, later I'll compile it. I let know you if I get any problem.

Epsxe will work on Gustsy amd64?

[Shadow-5471]

Neither. I have done all, but epsxe doesnt want to start. The output is the same:

andrea@andrea-desktop:~/Downloads/epsxe160lin$ sh epsxe
epsxe: 1: ELF


Linux
��44: not found
epsxe: 2: 1�X���T�P���RQ��: not found
epsxe: 4: Syntax error: "(" unexpected
andrea@andrea-desktop:~/Downloads/epsxe160lin$

I'm getting crazy...

Install ePSXe Playstation Emulator - Page 18 - Ubuntu Forums

It's the soultion of the problem.

Well I got it working by installing a new kernel, as you can see from my pic.

sh ePSXe does not work but if you enter the whole path the emulator will launch:
(eg. "home/shendo/Desktop/epsxe160lin/epsxe).

Thanks for posting the other solution, btw.

why not slim down the configuration a little while your at it, just do make menuconfig in the directory you extracted the kernel to and unmark any option under device drivers you KNOW you don't have (don't go too crazy though or you might not be able to boot)

Just to save people some pain, here is the non-kernel way to fix ePSXe (if you have the 32bit libs installed).
It seems that ePSXe is a UPX compressed executable, which seems to have an issue with that kernel.

sudo aptitude install upx-ucl-beta
cd /path/to/epsxe
cp epsxe epsxe_bak
upx -d epsxe

Just figured I would post the relevant parts here, since this is a logical place to look.

[Shendo]

Thanks for that, I linked your post in the ePSXe Linux config guide (near the end).

[g2g591]

wow, looks like recompiling the kernel was the wrong way to go. It seems it is an issue with the package, not us.

[Mad]

Yeah you just need to unpack the binary, it was packed using upx.

[Felson]

I don't think the problem is with UPX, so much as it is with the kernel not liking that version of UPX for some reason. I "think" it is a kernel bug. But, Buggy Kernel or not, I would rather stick with the one from the repositories then recompiling my own. That way when there are updates, I can be lazy and just let Ubuntu do it for me.
