RetroArch at Android

[ClaVahnz]

Hello all, I'm using Android (Asus Zenfone 5) and I've just downloaded RetroArch. I want to use it to play PS1 games. At now, I don't know how to use it.
Can someone please explain to me what must I do so that I can play PS1 games and any other console games at the RetroArch?
If anyone can share the full tutorial how to use RetroArch, it will be great.

Oh, and if I must download any additional files and/or the ROMs, can someone give me any suggestion where to download it?

Thank you very much.

I wouldn't know for RetrArch but most PSX emulators require a bios image to be extracted and used for PSX emulation and yeah you also need games to play in *.BIN+*.CUE format usually but some also support *.IMG+*.CCD or *.IMG+*.CCD+*.SUB if the emulator can you should always load the disc image via a CUE or CCD file

http://www.emuparadise.me/biosfiles/bios.html for the bios image/s
http://www.emuparadise.me/Sony_Playstation_ISOs/2 for the games but you may need to convert those to a single *.BIN and a *.CUE file, for more info on doing that see, http://www.epforums.org/showthread.php?57757 includes all the PC tools needed to be used before you copy over the disc image to your android device or micro SD

Personally I would just use epsxe for Android on its own. AFAIK retroarch is just a frontend for a bunch of emulators and you may find it easier just to use the emulator on its own as it is pretty much ready to go after the install except for needing the bios and of course the games as Zorlon stated.

Retroarch requires 3 specific PSX bios files, http://emulation-general.wikia.com/wiki/Using_RetroArch

Taken from the wiki,

If you are going to play in a system that needs a BIOS (e.g. PS1), place the BIOS files in RetroArch's 'system' directory.

Mednafen is very picky about which BIOS to use. The ones that you might need are:

scph5500.bin
scph5501.bin
scph5502.bin

If you can't find one of these, just rename the respective scph100x.bin BIOS (such as scph1001.bin) to scph550x.bin (such as scph5501.bin) and it will take it.

I use Retroarch myself, can be a bit of a pain in the rear to get it set up the way you want it but once you do , (and do that annoying procedure with multi disc PSX games) its pretty fun to use.
