Using a portable USB DVD-Disc drive to play my PS1, PS2, and Dreamcast Games

FFSamurai05

Greetings and thanks for reading. First, what I've done so far to hopefully stave off people who'd complain about my lack of effort:

I've already searched the forums and read the documentation but wasn't able to get a straight forward answer that way. The closest I was able to find was a post where someone wanted to use a CD as a replacement for a USB dongle or portable hard drive when loading up roms. As I want to play the original games in my collection this doesn't really help me.
I'm currently waiting on my raspberry pi 3 to come in the mail and am right now just researching different OS solutions so, as for testing it out immediately, not really possible yet. Want to do everything that I can do right now so that, when it does arrive, I can save myself a lot of time and just install what needs installing.
I have managed to get this working using my computer's built in bluray/DVD drive on my desktop for my PS2 games. That, from a power and processing standpoint, seems overkill for my purposes and isn't as portable as a Raspberry Pi so it's also a no go.

As the title says I want to use my retro pie to play my PS1, PS2, and Dreamcast disks. I don't want to rip the image or download isos, I just want to play my original games in an all-in-one solution that I'm hoping retropie can be. Can I just plug it in, do I need to download anything additional so that the emulators can read the games, and is there anything else I've not yet considered that someone on here can inform me of? Thank you very much for reading and, hopefully, giving me the answers I seek.

@FFSamurai05 as per the documentation, ps2 is not possibe on an RPI.

for ps1/dreamcast - they do work on RPI3, but i don't really understand your question:

how else you plan on getting your owned discs onto the hard-drive? you have to do one of these things :)

but yes, once you have a valid rom file, you can play roms via a USB drive https://github.com/RetroPie/RetroPie-Setup/wiki/Running-ROMs-from-a-USB-drive

@dankcushions im thinking he meant usb dvd drive.
@FFSamurai05 you cannot use your discs on any raspberry pi software. There is very few things that can use cd's like basilisk ii (old mac os) and dosbox, but nothing that you want to use.

I mean... Conceptually, if you'd insist, and you're curious/brave enough to test it out, I imagine you could try to pipe the content of the CD-ROM drive to an ISO file for the emulator's purposes.

I will state outright that this sounds both almost too crazy to work as to fail spectacularly, but you'll know it straight away :)

See if these help:

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.
