openMSX is a MSX , MSX2 and MSX2+ emulator. for people who don`t know what is MSX . It is a old computer since the early of 80's and check this link to know more about MSX systems

what really I like a lot about openmsx the great support for many MSX brands. you can get the System ROM for any MSX computer and run it with openMSX. as you can see in the screenshot i'm running MSX2 with Philips Machine. you can get another ROM for another machine and run it also.

it dose`t have save feature or dump for current session.

With openMSX you can run your favorite games / programs you used to play with 15 years ago or may be more . it supports disk images , cartage images and cassettes tape images.which is amazing i think i still have some cassettes taps i can digitize them to wav and use it."If it`s legal"

I think one day we will have emulators to our x86 machines while we or our children will be using something like ZsxX29990 ;-)
