About a year to 2 years before, Windows for PSP was released and emulated through Bochs. However the boot time of Windows 95 was about 7 minutes! Hopefully a new emulator called Dosbox was ported to the PSP, letting user play DOS games with their PSP. After a while DBS (dosbox boot selector) a plugin for dosbox could let users to boot normally Windows into the PSP. Fortunately the boot time of Windows 95 is about 1 to 2 minutes.. The Operating Systems ported to the PSP through Dosbox are just three: Windows 3.11, Windows 95 and Windows 98.For more information visit: http://djkman.freesmfhosting.com/index.php/topic,8.0.html
