ZIP support for Odroid-Go Advance (EmulationStation). Is it possible?

[maxmoon]

Currently I am trying out the official operating system V2.2 to play my favorite games.

The first thing what didn't work out of the box was, that none of my games have been recognized. After checking the es_system.cfg I've seen that there are no zip file extensions defined. So I've changed it and all my games appear. But I couldn't start it... it kept crashing. So I used ssh to log into my Odroid-Go Advance and check the command, which is used to start SNES games and copied and modified it to start my favorite game:

Code: Select all

retrorun -s ~ -d /opt/libretro/snes9x /opt/libretro/snes9x/snes9x_libretro.so /roms/snes/my_favorite_snes_game.zip

It shows following error in terminal:

I tried to install unzip and zip via ssh:

Code: Select all

sudo apt-get install zip unzip

But it still didn't work.

What am I missing here? Because all of my zip roms work on all other platforms.

Thanks a lot for your help.

Not all libretro cores accept compressed (.zip) content. Un-compress the ROM to use it. Note that other platforms that use RetroArch will transparently decompress a file. RetroRun does not because this causes flash memory like SD cards to wear out faster.

To start an emulator from the command line, you must first stop EmulationStation so the display is available for use.

Code: Select all

sudo service emulationstation stop

The standard Ubuntu repository packages should be available. You should post the error message to help determine the cause of failure.

RetroRun does not because this causes flash memory like SD cards to wear out faster.

This is a pretty good reason to unpack all roms on the sd card. I somehow thought it will unpack it temporarily in RAM and not on the sd card. For sustainability I will stop trying to get zipped roms to run.

This is actually a very useful command, because I tried to start the n64 emulator from command line and the emulator and emulationstation fought for the screen, which was a mess.

I somehow thought it will unpack it temporarily in RAM and not on the sd card.

This can only be done for some cores. Emulators that use CD-ROMs (PSP, PS1, DreamCast, SegaCD, etc) require a file. There is not enough RAM (1GB) to hold a fully decompressed ISO and run the system without a swap file which would also increase flash writes.

Is there a way to figure out which cores support the unpacking in RAM? I play SNES, Gameboy and NES games most of the time, which are really small games (~<2mb). And are there really emulators for the newer consoles (like PSX), which support zipped roms, too, because it sounds insane to unpack a whole CD or even DVD on a disk before playing a game (every time).

OFFTOPIC: I might change the os again, because I am not satisfied with the official operating system. I figured out how to activate hibernate on short power press, but if I come back to play again, the sound will be set to 100% and the network is gone. I don't care about network, but the full volume is pretty annoying and I only can fix it by going back to the settings and setting it by hand (every time), because I haven't figured out the key combination to set the volume (if there is any).

A core will specify "need_fullpath" if it does not support an image in RAM:

The issue becomes more complex when decompressing an archive. A .zip file may contain multiple files. These files may be in any order and have any file names. This means that additional logic to select the correct file from a .zip needs to also be added.

The reference image (official image) was meant to showcase the hardware. It was designed to be simple to get started with. It was expected that advanced users would select a popular 3rd party image that better suited their needs. Since no 3rd party images existed when the GO-Advance launched, the reference image was provided.
