Yes there are Nintendo 3DS emulators with working bios available. These bios can be found at locations such as 4 shared and Metacafe.
There are no working 3DS emulators at the moment.
There are no PS3 emulators and the bios file for the PS3 would not work in a PS2 emulator
on the website where you got the emulator
look up the bios on google look for scph1001 and put it in the bios folder in the emulators folder
The BIOS for the NES/Famicom is not legally redistributable. In order to legally obtain a copy, you must dump the BIOS from your console yourself. Most NES/Famicom emulators use low-level emulation and thus do not need a copy of the BIOS.
Gamers can download PS3 emulators from torrent sites. Torrent sites make it possible for PS3 fans to share emulators and BIOS files over a P2P platform.
You can download the Ps2 Emulating software and BIOS from http://pchelpsite.co.nr Click on the EMU link at the top of page. It works trust me. ++plus you can try to copy these file into bios folder at emulators
While Flipnote Studio can not be put on the 3DS legally, Hatena is working on a 3DS version called Flipnote Memo.
No. The game is only out in Japan and Korea, and emulators are not the way to go. Just wait for the game to come out and get it.
No, the 3DS will not read roms that are placed on the SD card. It will not read any unregistered game data from the eShop either if it was not bought on that specific 3DS (except for system transfer)
While PlayStation 2 emulators like PCSX2 have gotten better about emulating the hardware, the firmware (BIOS) of the PlayStation 2 is very unique. It takes time to reverse-engineer all the system calls that games make to the BIOS, so there is currently no drop-in replacement for the real deal.
Not that I know of, but I managed to find the BIOS files here: http://mmm-downloads.at.ua/load/games/emulator_files/playstation_2_ps2_bios_and_firmware_files/18-1-0-6 Just make sure you actually own a PS2 before you download it.
