NP2 for 3DS is an emulator for the Japanese NEC PC-9801 series computer. It is a port of [http://www.yui.ne.jp/np2 Neko Project II] v0.86. ==Installation== Release contains two versions, NP2 and NP21, both are available in 3DSX/SMDH and CIA formats. * 3DSX - Copy the .3dsx and .smdh files to the 3ds folder of your SD card. * CIA - Copy the .cia file to your SD card and install it with a title manager. Create a folder on the root of your SD card, it can be named either np2 or np21 (depending on the version you are using). Put ctr_key.txt, font.bpn and disk images on sdmc:/np2/ or sdmc:/np21/ (the folder you just created). Additionally, you can use your own biosrom to increase compatibility.

File formats for PC-98 are hdi, d88, nfd and fdd. ===Speed settings=== You can increase the running speed from Menu > 3DS, then select New 3DS.
