Had the same problem with all fenix games, and I had the runtime file in the gpsys directory.
I found out that it`s not running under Wind-Ups. When I start it with pacrom filemanager, it works fine.
I have had problems with these Fenix games too - some have worked and others havn't worked. Does anyone know if there is more than one version of the Fenix run time library?
I have noticed they are not all the same and you can only have one version on your SMC so I was presuming that some games work with specific versions of the library. Is there a universal version?
The launchers are fine, it just seems that the fenix runtime sometimes has problems handling the app path passed to it. I was going to do some investigation and post a fixed fenix runtime, but it uses SDL so I'll need to set that up first.
