First thanks a lot for all the work done by the OP and some of the people who replied! For me the tutorial of @Darkshade worked the best. One annotation though: The files provided are not truly empty. There is some binary data inside.
@swebley: Did you really get all 65 games working except Flo Boarding??? I had many issues and my success rate looks more like the Excel sheet compiled by @Talphadogg. I had many different types of problems. I'm trying to summarize them here:
Some games did not install and there was an error saying something about more than one app in the app folder. This I could resolve by removing the unwanted app file or by using a rom from a different source.
Some games did install, but did not show up in the app launcher. This I could sometimes resolve by installing the rom in a newly setup data folder of EKA2L1 or by mounting the card dump directly. The first solution is hardly feasible because I would have to start installing all the games all over again and then another game would most probably interfer again. The second solution does not work with Launchbox because there is no command line argument to tell EKA2L1 to run a card dump directly.
Some games do run if installed in a freshly setup data folder or if the card dump is mounted directly, but they stop working after installing some other games. If they are reinstalled they start working again (but probably break other games). For example Elder Scrolls.
Some games do only run if the card dump is mounted directly, but they don't if they are installed. For example System Rush.
Some games always crash at boot, no matter what I try (also on a freshly setup data folder and by mounting the card dump directly). For example Call of Duty.
I am using the latest version of the emulator: 1.0.0.9
What is your experience?
If someone really managed to get almost all the games working I would really appreciate it, if she or he could share her or his data folder.
