If you insist on ABI compatibility the best thing I can do is this
horrible hack. Add these two methods to GSGModelLoader:

- (NSData *) dataForFile: (NSString *)fileName
  // Horrible hack
  return (NSData*)fileName;

- (BOOL) loadModelData: (NSData *)data
     externalNameTable: (NSDictionary *)context
              withZone: (NSZone *)zone
  // Horrible hack
  return [self loadModelFile: (NSString *)data
           externalNameTable: context
                    withZone: zone];

Here we misuse the _nibData instance variable of NSNib to hold the file
name and use that name later on to load the GModel from the file. This
should allow us to load GModel files again.

That is my main problem. At the moment I cannot find any working
application that still uses GModel files. Could you please test the
above hack and report back, whether it works for you?

Thank you
