        I started implementing the python script I mentioned before and the comma doesn't make a good delimiter in the script since that is a quite common character in rom names.

        echo $(date)'|'start'|'$1'|'$2'|'$3'|'$4 >> ~/RetroPie/game_stats.log
        echo $(date)'|'end'|'$1'|'$2'|'$3'|'$4 >> ~/RetroPie/game_stats.log
        

        I updated the delimiter to pipe symbol. So update your run command to use this instead and remove the old game stats log. I'll make sure to share my python script when it's ready.

        Also, just to be sure, pipe symbol |is quite uncommon in rom names right? If not, which character would make a good delimiter?

          Here is the code: https://github.com/langest/RetroStats
          How to run:

          $ python retro-stats/game_stats.py -h                                                                                                                                            
          usage: game_stats.py [-h] -f FILE [-s SKIP_SHORTER_THAN]                                                                                                                                                         
          
          Process some integers.
          
          optional arguments:
            -h, --help            show this help message and exit
            -f FILE, --file FILE  path to the stats file
            -s SKIP_SHORTER_THAN, --skip-shorter-than SKIP_SHORTER_THAN
                                  skip sessions shorter than this number of seconds,
                                  defaults to 120
          
          

          or simply

          $ python retro-stats/game_stats.py -f game_stats.log -s 120
          

          It will print something like:

          {'gbc': {'Wario Land 3 (World) (En,Ja).gbc': {'times_played': 3, 'total_time_played': '0.0h 7.0m', 'average_session_length': '0.0h 2.0m', 'median_session_length': '0.0h 2.0m'}}, 'nes': {'Smurfs, The.7z': {'times_played': 2, 'total_time_played': '0.0h 10.0m', 'average_session_length': '0.0h 5.0m', 'median_session_length': '0.0h 5.0m'}}, 'kodi': {'': {'times_played': 1, 'total_time_played': '0.0h 25.0m', 'average_session_length': '0.0h 25.0m', 'median_session_length': '0.0h 25.0m'}}}
          

          As of now it prints number of times played, average session length, median session length and total time played.

          What I am planning to add in the future:

          • Global and per console top list
          • Time since last played
          • Prettier print
          • Choose delimiter via argument

          Also clean up the code and make a proper package of it.

            @langest so an entry with less of 120s of playtime is ignored by default I assume.

              @cyperghost Yes that is correct. In case you accidentally started the wrong game we don't want don't count it. But you can just pass in -s 0 and every entry will be counted.

                  I have put in more or less the features I want in the tool now. I will probably add some more documentation on how to use it.
                  If you want to try you can use it like this:

                  $ python3 retro-stats/game_stats.py -f game_stats.log -s nes -c times -m 120

                    I totally agree. I don't know what support themes have to add custom data fields. I guess that is up to the theme, emulation station or pegasus devs et.c. to figure out.

                      @mitu Do you think this would fit somehow into retropie? And maybe you know who else might have a say if it could be part of the system.
                      Maybe it could fit into a menu entry in the emulation station start menu that lists your statistics?

                        @langest If you'd like to add something to RetroPie, just create a Pull Request on the Github's project.
                        Personally, I think it's nice, but it's not something that I see included in the base image. Don't let this discourage you from developing it further, though :).

                          I added support for using skyscraper cache for getting rom names to get a prettier print. However, it is much slower. I haven't profiled the implementation, but I might optimize this at some point. Also, it doesn't seem to work for all the systems. Probably has to do with which files skyscraper uses to calculate the sha1 sum.
                          If you want to try it:

                          retro-stats/game_stats.py -f ../../RetroPie/game_stats.log -t ~/.skyscraper/cache/
                          

                          Pass the path to skyscraper cache to the -t parameter.

                            @langest I see this as usefull information for the MAME RoWs ;)

                            Hmmm.... I think this could be made better by using bash dialogs.
                            So you parse your output to info box and you can scroll and select with joypad.
                            Then I'm sure you will hit a wider audience. If you can do some coding in python then you can also set some bash scripts ;)

                              Yeah, that could be the next step. You don't really need to rewrite the script in bash though.
                              You can call the python script from bash and just format the output nicely into an info box. Would be a nice project to learn some bash.

                              Seems like the sha1 sum is different for the arcade games as well. Maybe has something to do with them being ziped.
                              I think I will try to fix this problem before I create a bash module.

                              Maybe @muldjord can point me in the right direction to figure out how and for which files skyscraper calculates the sha1? (compressed files and .cue are the ones that doesn't work)

                                You explainded later the correct situation

                                You can call the python script from bash and just format the output nicely into an info box. Would be a nice project to learn some bash.

                                👍

                                  @langest Depends on the module. For ScreenScraper it does a sha1, md5, crc32 and exact filename search. If either of these return a unique result, ScreenScraper will hand back the game data. For the other modules it is filename search based. So if you have a good filename, you will have pretty good results aswell. So, for instance, a filename of "abrq10.zip" is a poor name, as it makes no sense to search for. If instead it is "Game_name_1.zip" is will work a lot better. But there are some nifty tricks on top of that which I do. For both mame and scumm names I have a lookup which converts the names such as "Golden Axe" instead of "goldnaxe" (or whatever it's called).

                                  All of the modules are described here, which should provide at least some insight as to how each work when looking up roms.

                                  Lastly, the CD based platforms are notoriously hard to scrape, as they often have multifiles per game and / or are based on .cue files which can vary since they are often user generated. So for these platforms even ScreenScraper is highly reliant on the exact filenames instead. So it will need to exactly match, for instance, "game_name.cue" inside of ScreenScrapers database to work.

                                    Thanks for the informative answer.

                                    What I am doing is parsing the db.xml files. And in there the entries are stored based on sha1sums. When I use sha1sum on a rom (and when I use it in my python program I get the same result):

                                    $ sha1sum roms/arcade/joust.zip
                                    48c27d4b623b83e3e724ed348b40ff6193b92b1e  roms/arcade/joust.zip
                                    

                                    It is different from the sum in cache/arcade/db.xml

                                    <resource sha1="ed1455f34143e6781dc443c064ca7d69e4093cff" type="title" source="openretro" timestamp="1562952656836">Joust</resource>
                                    

                                    Same with .cue (understandably)

                                    $ sha1sum roms/psx/Bishi\ Bashi\ Special\ 2\ \(Japan\).cue
                                    3d1fb64cd75afd208f7eedb3059a0b0a09fbb78a  roms/psx/Bishi Bashi Special 2 (Japan).cue
                                    
                                    <resource sha1="cdd966e49743a5571eeb81d249d6a3abefbfb408" type="title" source="thegamesdb" timestamp="1563723954281">Bishi Bashi Special 2</resource>
                                    

                                    It works fine for files that are "plain" roms:

                                    $ sha1sum roms/gbc/Wario\ Land\ 3\ \(World\)\ \(En\,Ja\).gbc
                                    bb7877309834441fd03adb7fa65738e5d5b2d7ba  roms/gbc/Wario Land 3 (World) (En,Ja).gbc
                                    
                                    <resource sha1="bb7877309834441fd03adb7fa65738e5d5b2d7ba" type="title" source="openretro" timestamp="1563722070330">Wario Land 3</resource>
                                    

                                    Do you know why this happens?

                                      @langest imho the FBN/MAME games or fixed by their names.
                                      pacman.zip is always PACMAN independent from ROM version.

                                      About PSX games .... if you check the bin/img file. Did you then get a result?

                                        I also figured out why using skyscraper data is "slow". It is because you might be reading and hashing a big file, dreamcast rom et.c.
                                        And the IO is what takes the most time. I have added a function cache to reduce this problem. But it would probably be best to cache all the results on disk so you don't have to recalculate it every time you run restart the program.

                                          @langest said in Game statistics:

                                          Isn't Skyscraper already doing this ? You could compare the timestamp with the file date and rely on Skyscraper's already built cache - of course, for entries which are present there (i.e. without roms added since the last scraping session).

                                            @langest Ah, you mean the cache rom id's. Yes, they are a mix of sha1 sums of the actual rom data and sha1 sums of filenames, depending on whether the input is a script (or zipped, read on for explanation) or an actual rom. So in the case of .cue files for instance, it is a sha1 of the filename. If the files are more than 50 megs, they are also id'd by the sha1 of their filenames for speed optimization. But please know that the cache rom id's are completely separatate from the checksums I do when using the ScreenScraper module. In fact I was thinking of renaming the "sha1" attribute in db.xml entirely to just me "id" as to avoid confusion. But then that would break backwards compatibility and the db.xml files aren't means to be edited by hand anyway. It should always be edited with --cache edit.

                                            And there's reason behind the madness. I could just id the files by filenames. But some people like to have games in subfolders and potentially have two games with the same filename under the same platform even if the games are different. To avoid this I use the sha1 checksum instead. But of course this doesn't make sense for scripts, which change often. So for those I have to use the sha1 of the filename instead. I also always use the sha1 of the filename for zipped files, since people might unzip them and rezip them. This would also break the id for that game. So yeah, there's some considerations behind the madness, just to let you guys know. I'm not saying it's the best way, but it's kind of locked in now, as to avoid breaking people's caches, and it works well (although slow, as you point out, for the bigger roms) so.
