It is possible that most video game machines from the 32-bit era could be emulated on the PSP with a functional Playstation emulator, GBA (it has a 32 bit CPU) and even N64 showing some promise concerning 32 bit consoles though, Sega Saturn emulation is highly unlikely, as is Dreamcast. The PSP, despite its apparent low clock speed when compared to those of modern desktop PCs (PSP uses a MIPS processor, while most desktop computers now will use x86, so MIPS is more efficient and thus will get more done per cycle), is a powerful system. As such, you need ROMs for each system and an emulator for each system (though some special cases exist such as MAME which will run ROMs from multiple arcade systems). ROMs for one system will not work on another system's emulator, just as you can't plug Super Nintendo cartridges into a PlayStation and run them. In general, these are illegal under copyright law unless you dump them yourself (and even then you are only allowed to make use of them under very specific circumstances). These normally come in the form of ROM dumps (since they are extracted from the ROM chips that used to be used to distribute software) generally known as just "ROMs". These dumps cannot be distributed legally without the permission of the company/individual who created them due to them being copyrighted.Īn emulator is no use without software to run on it. In most cases, emulators can simply be loaded into a homebrew-enabled PSP however some require a dump of the BIOS ROM stored within the system itself. Of course, it is also portable meaning you can play these games whenever and wherever you want without having to carry a TV, machine and collection of cartridges. Furthermore, it has a 480x272 resolution LCD which is large enough to accommodate most older systems without any downscaling. PSP is suited to this task because it has a fairly standard control layout similar (or almost identical to) the layouts of the input devices of the systems it emulates. Oswan and WSCamp were the recommended emulators according to the article.One of the most popular uses for the PSP in homebrew is to run emulators of old video games systems (though some old home computers and calculators are also emulated). Old feature covering early WonderSwan emulation.
