First, thanks for replying to me here and pointing out the error in my title. I want to try and use a portable disk-drive to play PS2 and Dreamcast games so I've updated it accordingly. As for why it's really for the same reason someone would want to play an NES game on the original cartridge, even if they're using a Retron 5 or some other device that employs emulation. It's what I grew up with and, since the purpose of this device is in part to relive that nostalgia, I figure it's worth trying to make work like this. I've heard elsewhere that, though PS2 games due to the raspberry pi's architecture are out of the question, Dreamcast and PS1 disks may still work so I'll post an update once I get the components and can test it out. Thank you all again for the replies.

@backstander no worries, I've never used it myself anyhow :p

@backstander

Oh, thank you, finding a pokemon_light_platinum_final.gba.zip worked! I don't know what was wrong with the other ROMS, because they all worked in the PC emulator with only some minor setting tweaks. That's odd, but as long as I can get it to work that's fine with me.

@Ecks might as well not use the top part of the case then if you're gonna put it into a bartop with a fan.

You might wanna check with Selsine on these bugs.

You can also use the Configuration Editor (instead of editing /opt/retropie/configs/psx/retroarch.cfg manually)

RetroPie Setup Script >> Setup / Configuration >> Edit RetroPie/RetroArch Configurations

@jay81uk unless you want to start manually erasing files

Hello,
couple of weeks passed and things happened.
First, it turned out that the autoconfig files in the retroarch-joypads directory contain different values than the jstest tool prints. This is pretty confusing to me but when I executed the builtin joy configuration tool of retroarch, it created the file with different values for the two gamepads. And the buttons works with those 'different' values. So much for jstest. (I guess libretro doesn't use SDL2, but EmulationStation). Interestingly the scancodes of the joys are the same for jstest, but different for the retroArch config...

Secondly I visited the irc channel of retroArch and there I was told that the joys/gamepads are recognized by their name, vendorID and productID (bluetooth address doesn't play any role in this procedure - which is again surprising for me). These values are the same for my pads, so only one option is left for me: forget about autoconfiguration and configure the pads manually.
Now in my retroarch.cfg file I

turned off autoconfiguration (input_autodetect_enable), so upon lr- game start the joy config files are not re-loaded configured the scancodes of the buttons/Dpads/axis in the retroarch.cfg file for both joysticks..

Now I can play Super Bomberman 3 happily with my kids in two player mode...

Thanks for reading!

Ah, should have read the rules properly sorry

@edmaul69 oh that's really good info! I think it's possible that by converted bin + cue are the real problem

@pbizzle said in Where are the ROMS?!:

@dankcushions should all the ROMs be .zip files?

not for all systems, no. you can find out the possible extension(s) for a given system by looking at the wiki page. eg https://github.com/retropie/retropie-setup/wiki/Super-Nintendo-Entertainment-System

@simonster

Thank you for your reply, yes i have switched power supplies and the green light went off before i switched it off. I did not replace the sd card however as it is the only one i have and i will not be getting one soon.

What i plan to do today is to redownload retropie and redo all the whole process again. If it fails, i will safely presume that it is my sd cards fault.

@cyperghost
Thankyou for your reply, I went down the route of having two split systems, seemed more logical for me.

@Hex IS there a way for me to access any save states that I have on the card in order to back them up? I think that formatting and reinstalling Retropie might be the easiest choice but I don't want to lose my data.

Can you give me more details about how to use the Disks utility? Is this something that has to be run from my Raspberry Pi? Or can I plug the sd card into my Ubuntu computer and run the utility on there? Same question for the sudo fsck /dev/mmcblk0pX command - is that something that I can run from my Ubuntu computer with the sd card connected without causing problems?

@mediamogul Awesome Thanks!!!

So I played around a bit, got a new SD card with the image on it.. did all the typical tweaks (enable wifi, disable overscan). I then followed the guide up to editing the fstab. Plugged in the UUID appropriate for my drive, and used this command:

UUID=******** /home/pi/RetroPie ntfs rw,exec,uid=pi,gid=pi,umask=022 0 2

Essentially, I'm using the vfat example in the guide, and just changed it to ntfs. The rest of the options I'm not sure what are for, but it looks like user permissions (like read/write/execute/etc) for the path and it's specifying the user as pi so I left that in there from the example. I'm not sure about the umask bit, so I just left it too. If somebody can clarify on what all those are, I'll edit my setting if needed. But for the most part, it looks like it's working. I was SFTP'd into the Pi prior to rebooting. I could access /home/pi and everything else on the system just fine, but not /home/pi/retropie. However, after rebooting, that last /retropie/ bit opened up and gave me access to things like the bios and roms subfolders. So I'm assuming that means the automount DID work. The only way I'll know for sure is if I transfer in bunch of files over 8gb, because that's the limit of my SD card. :)
