The Amiga Future 149 was released on the March 3rd.
I doubt that very seriously. Yes I am a programmer but I don't program on pcs but on IBM mainframes. I would screw things up more than help things along. Also I have no exposure to any pc languages that could accomplish the task.
I don't see where the problem is or I don't understand. Take the LHA archive and depack it on your pc or whatever suitable device you have. Than make ADFs with the tools Thomas suggested, i.e. copy files to/as ADF. Take this to your Gotek and reverse the files to ADF procedure. Install Roadshow and you should be done. It's more or less just a file transfer from pc to Gotek. Do I miss something?
