windows run amiga games too, under emulation like mos or sam.
Little bit different ballgame there. Entirely different ballgame in some cases. OS4 or MOS I can run some entirely "legacy" software sans emulator. I have no emulator on my SAM 440ep. *NONE*. No 3.x ROM's even, no UAE variants. I can fire up LW or ADPro just fine with no need for any emulator on the SAM.
Zeus BBS is the example I'll use, simply because I run it each and every single day 24/7 without the need for *ANY* emulation software. A completely 68k application from the 1990's. No emulation at all. Starts in user-startup and runs just like it did on my old A1200. No emulation layer at all. None. Nada. The machine has no emulator on it like UAE other than Petunia, which I assure you doesn't do much.
I can fire up my MOS machine or my OS4 machines right now and run legacy code without an emulator layer. Period. No argument about it.
I cannot do that on Windows, Linux or Mac - and while I am picking nits, your allusion to the fact all legacy software must be run via emulator on a NG machine is a false statement.
