Windows 95/98, making it workable on the psp, possibly.
^^ this should work for anyone, it shows how to make windows 95 WAYYYY smaller, like 35 mb as long as you have the cd (or iso) lol.
anyone want to try making an image and booting it, i havent downloaded any of it yet. I'm going to try, but hey if someone can do it faster than I can great. :Jump:
edit - requires the window cd i think...
edit JUST found this
runs with 8 mb ram at a 1-3 second bootup
"Tiny! installations as small as 9MB, 11MB for networked install with Explorer GUI
Lightning FAST bootup (as little as 3 seconds to the desktop!!)
Instant on/off - just hit the power switch
Run from flash memory as small as 8MB - even removable USB keys!
Compatible with all existing Windows 9x hardware - a huge array of drivers at your disposal
Ease of use and familiarity with the OS and software development tools "
just some ideas...
it cost something, it just doesnt have a price on the site...
