On the other side, there was Basilisk II. While DOS emulation was pretty decent with a mouse-enabled shell, it still proved to be a tad clunky because of hard to use keyboard input and the fact that the iconic DOS 640×480 resolution didn’t really scale very nicely on the PSP’s screen (480×272). DosBox on PSP was a tad clunky to use when it came to keyboard input and it had one big flaw with Windows 9x anything written to disk wasn’t saved after quitting DosBox so it made doing anything on Windows 9x purely useless as it disappeared next time you used it on your PSP. While many people have fond memories of their old Windows games, DosBox on PSP barely booted Windows 9x let alone run fast enough to even play the most basic of games such as Hover! (a game that was bundled on the Windows 95 CD). The main choice for 90s computers was between two giants, Apple and Windows computers.
Most of them are quite clunky, slow and overall painful to use and that was true for some 90s computer emulators on the PSP such as Bochs which was nothing more than a Proof Of Concept. Computer emulators have been a thing for quite a while on portable devices but they are rarely useful enough like say, console emulators.
