I think you mean Doom on WinUAE 
Cloanto didn't write any part of that code there. Amiga Forever is just WinUAE + free crap @ arse raping 30 euros :roflmao:
Have you looked at what's in the Amiga Forever package lately? There's a whole stack of stuff, most of which is *not* free. Pressing CDs and DVDs isn't free either. Oh, and it's not 30€ either, it starts at 10€.
If you're going to complain about something, it's generally useful to have at least some knowledge about what you're complaining.
