I would buy out Cloanto and make a Retro Player, kind of like amiga forever setup but have a store section like apple and have maybe the A500 setup with ks 1.3 rom free and then charge like £1.99 for each extra system you wanted as well as have games available to purchase, then try and expand the service to offer legitimate ways of obtaining say sega system or Nintendo systems, and have all the games in the retro playing format, make it as easy as possible for the end user to play these games, maybe make a very small console like system that would just boot up into the retro player.
I know it pretty easy to get you hands on emulators and systems roms, but the average jo believe me doesn't know how to set up most emulators and the whole scene is just a bit of a legal mess, it would be nice for someone to build a front end easy simple all in one solution to run any old game no matter what the console or format.
That sounds a lot like the GameGadget thing that blaze is bringing out. It's like a multi emulator thing that has an itunes style store for buying roms. So in a sense, if they could find a way of bringing some of the basic platformer and shooter games to this device it would fit in nicely.
Hmmm what would I do if I owned the Amiga trademark... and some capital...
For starters some internet changes would be required, I'd buy A.org and have it redirect to AmigaOS.net and build a forum there where people could safely discuss Amiga NG. There would be no 'retro threads nor 'other OSes' threads, any detrimental talk about any other AmigaOS-like operating system or even the classic range would be deleted without warning by my moderation team. Amigaworld.net would cater for all that 'Noise'.
Whilst this 'cleansing' is taking place I'd then meet Ben Hermans and discuss how the remaining capital could be best invested to not only sustain, but improve OS development.
Think you have just managed to annoy a few people with that little nugget.
