MAME devs? No, an authour for illigal MAME. He will create MAME with plug-in system to "enjoy" playing the game than the emulation.
> demul etc is better than Mame like some people are thinking.
Why some people (and you) does think so ? ...I guess these emulators are better to "enjoy" playing the game comfortably than MAME. So some MAME with "hack" (not correct emulation) is still respected and even some respecter requests to official. But I think base concept between MAME and other emulators is different so that comparing both in the same line is so strange.
> We should be happy and greatfull for them both
It may be very happy and greatest for some people who think an emulator is a toy of free game and all ROM images are "downloadable" freely from the internet. Copylight ...? Emulation ...?? What is it? Does it taste good? ... they may say so.
"Any company has no power to stop people emulating"
MAME is the emulator of no giving in the pressure from any company even if they don't allow
