0. Get something like UAE / WHDLoad that is under the LGPL and integrate it into the OS to allow running of metal banging games (from images) and apps (from executables). Petunia as i understand would not work with metal banging apps, but could easily provide the CPU emulation. Make sure it allows multitasking.
Agree fully..
1. Release an "Amiga Classics" title for the Wii, Playstation, and XBox 360 (all ppc i think) to milk funds from those who loved the Amiga in their youth, but treated it as a console. Such compilations (e.g. Atari, Midway) have done well before, as Retro-Gaming is quite chic. Give a percentage of the royalties to Team 17, Bitmap Brothers et al.
Again i agree.. Either that or they should launch something similar to the c64 in a joystic.
5. Continue to supply support to the "faithful" users of Blizzards, AmigaONE and Shark PPC's (give them a Cheaper OS, especially for AmigaONE owners who have the encryption hardware built in i think).
I dont agree so much about this one though.. I think it is about time we move ahead from the classic. Though we need a stable and modern platform to be able to do that and also like you said we need some built in hardware banging emulation, so that we can still play the good old classics.
6. Don't bother with X86, too much work has been done on PPC, and most of the target market would have the hardware (be it a console, a possibly-now-spare-PPC-Mac as they've gone intel, or a specialized amiga system).
Here i must say that i totally disagree with you. There is no affordable and modern PPC hardware available. If we continue in the ppc, we will most certainly see another amigaone tragedy with hardware both being full of bugs, underpowered, expensive and then eventually be out of production.
You could lock OS4 to just one certain specs in the x86 world as well. The difference would be that the hardware is more available, cheaper, more horsepower and mature which means more stability.
