Step 1. EmulatorGet an emulator, either from Google Play or our Emulator Section. Emulators are apps such as SNESoid, Tiger Arcade, Ataroid, etc...
Step 2. BIOS** Required for: PSX, GBA, NEO GEO, and some Atari emulators, otherwise skip this step.
If using any of the emulators listed above, you will need to download a BIOS File. To get a BIOS file, please visit our BIOS page. You will need to unZip the BIOS (.bin file) and place it in the same folder the ROMs are in. Don't forget, this is very important.
Step 3. DownloadDownload any ROM from this or any file-safe website onto your computer.
Step 4. ConnectConnect the USB cord to your Android mobile device then to your Computer. On your Android device, you will get a notice such as "Turn ON USB Storage" (this differs on phones). Just make sure your phone is connected to your computer.
Step 5. CreateCreate a folder called ROMS within your Android mobile device (Organization). You can do this by accessing your Android device through My Computer, it will show a new device there. Open it then create the folder. I create my folders at: /sdcard/download/Roms/ or /sdcard/ext_sd/download/Roms/.
Step 6. TransferTransfer all games you've downloaded into the ROMS folder on your Android mobile device. Don't forget to transfer the BIOS File as well. Remember to click Turn OFF USB Storage when you are done! This safely un-mounts your SD Card.
Step 7. PlayOpen up your emulator, if you needed a BIOS, be sure to load it first. You can do this by going to MENU -> SETTINGS -> BIOS FILE. Afterwards, hit the back button on your phone till you reach the black screen with files, then navigate go to your ROMs folder (/sdcard/download/roms/ or /sdcard/ext_sd/download/roms). Just double tap the game of your choice to start playing. If the game does not play correctly, you may need to modify settings such as frame rate or enabling special features. OH yeah....most importantly, make sure to have fun and if you have any questions, visit our forum: http://forum.roms4droid.com
*Note: Lite versions or also known as free emulators, do not have "save state" unless you purchase the product. This rule is void if the full emulator is free, duh! :-)
