Nice write up Die and Ttown. I initially purchased 2 Gbox's to run Kodi, but am now itching to get a Raspberry to easily update and reload my stream boxes. And was looking into the possibilities of ROMs. Sold now.

Link

This link is a pretty simple instruction list on how to do it and what equipment is needed. It also describes how to transfer the game Roms to your running raspberry pie via USB stick which I skipped over in my post on the first page. Again, you can also transfer Roms over wifi which is even easier than this USB method, but the wifi way isn't talked about in this article.

Also in the setting up retropie section, they mention "You will also need software that can extract a .gz file." This is the 7zip software I wrote about on the last page (the step I accidentally skipped). DL 7zip for free. Then right click on the Retropie file you DL'd, click 7zip and then click "extract here". That's it. The .gz file will appear right next to where you DL'd the retropie file initially. Then you use the gz file for the win32 step to write retropie onto your sd card.

The tricky thing about MAME roms is that they have a version number themselves. I found that I had better luck running MAME 2003 with MAME roms that are version 0.78. To use MAME 2003, the 0.78 roms must be placed in this path

SF2 through SSF2T work great with this method


Yeah, my issue is that apparently keep DL'ing arcade roms with incompatible rom set codes. Any easy way to find the MAME roms version number? I wish the rom code would just be listed in the details sections of each ROM before downloading it. I guess that would make it too easy for everyone

The available versions of SSF2T on emuparadise don't work with any of the arcade emulators. At least they aren't working for me. The SF2 Roms work with MAME 2003 though. I haven't tried any of the other SF games.

The code for each arcade emulator is listed on the retropie website, so that's easy:
MAME4ALL - 0.37b5
AdvanceMAME - 0.94
MAME 2003 - 0.78 (as you mentioned)
MAME 2010 - 0.139

Finding the compatible ROMS for each can be a bitch it seems.

There really isn't because of the variability of the contents of each rom and the disorganization of the sites that tend to host them. I can't locate it at the moment but at one point I found a site that had the contents of each arcade rom zip file listed so you could more easily figure out what files you might be missing and what the sizes of those files should be. I manually "built" a couple of roms this way at some point but it honestly ended up being way more trouble than it was worth.

To find the set of roms I'm currently using, I think I did a Google search for: MAME2003 0.78 roms

...and then used the torrent in the first or second link. That's not to say that all of those roms worked with RetroPie's Mame2003, but the ones I wanted did for the most part. There are always exceptions, though. For instance, I can't get Mortal Kombat 2 to work for some reason, though MK1 works fine. I haven't attempted to dig into it too much, though, mostly because I don't really care that much about MK.

yeah, I am not looking to do much rom set building either for the arcade games. I saw there were programs to do that, but I don't want to get caught up in it. I am more of a download, copy & paste and then play kinda guy. Any more work than that and I'll just wait around until I find a working file already online.

I'll try the simple google search to see where that leads me. Thanks

I use Recalbox instead of RetroPie. I've really liked Recalbox, but is there any reason I should consider a switch to RetroPie?

Here's an article explaining the differences. The TLDR version is that RetroPie allows more control and customization but Recalbox is easier to setup. I picked Retropie because I was able to find more information on it when I started and I enjoy tinkering with the inner workings of things.

If you're happy with your Recalbox setup, I don't see any reason to move to Retropie.

I'm a little late to this thread, but let me add my two cents that yes, getting an RP3 to use as an emulator is absolutely worth it. I love mine, and the fine folks who make RetroPie made it as easy as they possibly could to get everything set up. I can't recommend it highly enough.

It's relatively easy. Atari and NES games work great. Commodore 64, not so much. They tend to emulate poorly. Too bad because those were some of the best.

Almost pulled the trigger on a NES classic until I saw this thread. The classic is perfect for traveling however the Pi looks to be more compact even enabling bluetooth would remove even more clutter. Shouldn't be any trouble considering HDMI/RCA connections one would think?

The Pi itself fits in the palm of your hand. There are multiple different cases to choose from for the finished look (search amazon/google for raspberry pi 3 cases), so finished size entirely depends on the case you choose. Most cases don't add much bulk though and are sturdy enough to travel with.

Controller, power supply wall plug and TV connection are the only other items needed to play, so it is easy to travel with.

Not an expert, but it's just the graphics and all that encompasses running that size of file. The funny thing is I started this thread because I plan on getting a Switch to play N64 and Gamecube games as well and it got me thinking about emulators

Maybe I'm misunderstanding but I don't see how the Raspberry Pi 2 (or 3) would struggle to run a Commodore 64 game but emulate most Playstation games just fine. The only explanation would be if the state of C64 emulators are in really bad shape like the Sega Saturn but that also seems unlikely. Also, I would be surprised if any C64 roms even break 1 MB in size. PS1 games are hundreds of MB's, though most of that is from the video and audio files.

I might throw some C64 roms on my Pi soon and see for myself but there are several videos on Youtube of people playing them just fine.

Performance for most of the emulators are 100% accurate. Graphics seem to be worse than what we remember, but mostly because we are running crappy 8bit and 16bit graphics on our 40"-60" 4K/UHD TVs, so they tend to stand out

There are graphics options in the settings that you can use to change the resolution and iron out some of the pixilation. And you can change each emulator to run different graphics settings, so you can set each one up to your preferences. In then there are the shading/filter options that DieDaily mentioned on the first page of this thread to help even more.

It'll never be perfect graphic emulation, but there are ways to drastically improve the out of the box graphic settings.

I haven't seen it mentioned, but has anyone tried a DreamCast emulator on these?

Dreamcast is supposedly pretty buggy. Haven't tried it personally

That's what I figured unfortunately. There's a few games on there I would want to play like Crazy Taxi, which I'm guessing you couldn't play the arcade version of it. For arcade racing games that had the actual wheel and there was a World Series 99 arcade game that used a lever for hitting, can they change it to where it's a button?

Where'd you do that? While there would be the personal satisfaction of building this on my own, I feel like I would screw up a small detail and not realize where I did it

Dreamcast emulation is still in the early stages for RetroPie. Many games don't work and the ones that do don't run at full speed and have audio / video glitches.

Here is a video from a few months ago showing some Dreamcast games running on a Raspberry Pi 3 in case you're curious.
