There have been some Nintendo DS Emulators developed by some kind souls, however these products are called Homebrews and they require the use of a PSP with Custom Firmware. It can be a difficult process however you can research the information on Google and see how you can go about downgrading and moding your PSP so it can play Homebrews. However this is potentially damaging to your PSP and can lead to bricking (aka making it basically useless).
You have to download PS, PS2 emulator and MR roms to play on PC. My Monster Rancher only runs on Android and IOS.
get a n64 emulator then buy a DUAL PS PS2 CONTROLLER TO PC USB CONVERTOR ADAPTER from ebay
No the PS2 plays select PS titles with a emulator which is easier with the less complex PS games than it is for the PS2 games in the PS3. That is why the PS3 still plays select PS games. Emulators do not play every game like the original PS did
No the Playstation does not play PS2 games
No it was designed for Playstation 2 games and while it can play some PS titles it can not play Xbox or Xbox 360 games
No you can not
Some titles will play
You can "play" PS games on the PS2
No you can play PS2 games and some PS titles only
You can not play a game cube on your PS2
Sorry, you can't. A computer's CD or DVD is not the same as a PS2 drive, and cannot decode the disk. PS2 games are burned with certain marks on the disk that distinguish it as a PS2 game disc, which is why you cannot simply copy and play games (unless you have a MOD-chipped PS2). The best PS2 emulator can only play certain demos and homebrews, but not commercial games that you would buy in the store or rent. However, there are some PS1 emulators that will allow you to play an original PS game on your computer.
The PS2 will play legal PS games that are not from a different region or illegal burnt copies of PS games for most titles
