I think it’s fine, it’s actually the first time I boot it. Edit: checked the cue sheets and also made a single track (it’s a multitrack game) but didn’ t help. Same game (equal md5sum) both multitrack and single track run fine on same core on PC.
Same problem here. It’s annoying. I googled and didn’t get any useful information. It’s wired that few people talk about this problem.but I got it working.the method is to load the game of course and call out the quick menu immediately before the emulator craches (it’s totally possible.there is about 1 second between loading and crash.) Once you are in the quick menu, go to “disc control” and select eject disc.then “resume”. Now you should be in the Sega Saturn’s bios. It’s a good sign. At least it’s running and stable. Call out quick menu again do the same thing. Just this time select insert disc then resume. You will see that beautiful SEGA logo. Enjoy!
This core works perfectly on Windows. but I have this issue on android. really don’t know why. But this method is actually just bypassing the saturn animation before the SEGA logo.so that makes me think that it’s the saturn animation that caused this problem. I don’t know… it’s annoying. Except this issue this core is actually amazing. It runs all my favorite games with full speed. I wish this could be fixed later on.
By the way. My phone is sony xperia 1. Android 10. It’s fairly powerful. Retroarch runs very well on it. Version 1.9.0
Hope this could help a little bit…

I am having similar issue to yuanye8425. I have a chd file and saturn USA bios. both work on beetle saturn (windows). But on beetle saturn (android) the chd crashes on load (but before the bios screen). Bios file is in the correct system folder. When i try the pause, eject, insert new disc method above i get to saturn bios screen. However, it only detects the chd as an audio cd so i cant play. I don’t think the chd is bad because i can load and play that same chd on yabasanshiro (android).
What do i need to do to get beetle saturn (android) working?
can anyone out there help me?
Try the ra32 build: http://buildbot.libretro.com/stable/1.9.0/android/RetroArch_ra32.apk
Beetle Saturn works on my phone with this 32-bit build, but crashes during game loading with 64-bit RetroArch. Only tested cue/bin disc image.
I tried this build. beetle saturn wont crash on load now which is good. But it takes me to the bios screen and wont load the chd. It still thinks its a cd. Again i know the rom is good because i can run the same chd in yabasanshiro
That’s because Beetle Saturn’s CHD support is buggy: Bug in CHD support for beetle saturn core
This also happens on Windows. It worked with all cue/bin & cue/iso/wav disc images I tried. With converted CHD, it just went to CD player.
That was super useful, thanks a lot.
Beetle is still slow, but at least it’s playable now. And right now it’s the only working Saturn core that supports cheevos , since Yabause got yellow fever on Android 
Ok, something bad happened, because after updating Retroarch to 1.9.9 and updating the cores @yuanye8425’s workaround no longer works.
Beetle Saturn crashes RA on Android regardless of ejecting the disc

ah… Great 
but I tried minutes ago. RetroArch plus 1.9.9 . That method is still working.
Hmm, Retroarch Plus from Google Play? I’m using a standalone APK downloaded from RA buildbot.
What is the version number of your core? Mine is v1.22.2 f509c39.
Yes from Google play. But the core version is the same.1.22.2 f509c39

Now this is super weird.
I downloaded Retroarch Plus and I had the same result as in standalone apk earlier. So it is neither the version of the core (as they were the same), nor the version of RA (as the problem persisted even in RA Plus).
So it looks it’s something on my side. I reset all my core options to default but it also didn’t help.
As a last resort I decided to replace my existing BIOS files in RA system dir with freshly extracted ones from my archive. Aaand… BAM, it worked!
I can’t really explain what happened here. Was it that my files got corrupted?
But I keep them on my internal memory instead of an SD card (which is more prone to corruption).
This is really some mysterious bug, but maybe this solution will help someone, as it’s totally not an obvious one.
Glad you got it working. Beetle Saturn is a pain in the ass on Android… But it awesome when it’s working. Interesting enough. Few people mess with Sega Saturn core on RA nowadays. Especially the kids. They don’t even know a thing about this amazing but flawed beautiful old console.But people like us just won’t forget it. I just love it so much.it brought me so much fun back in the day.so I guess you are also old enough to love this machine. Correct me if I was wrong 
even though. I have had enough of messing this core on Android. Windows version is just so good. And I don’t think devs will fix this issue soon. So let it be.

Yup, I’m even old enough to remember 2 generations before that 
Although at that time home consoles were not so popular where I come from. NES was practically unavailable apart from some unlicensed clones. Things started to change with PSX/Saturn/N64 era, but it was always PSX that was infinitely more popular in my country.
So Saturn was pretty much unknown territory for me for a long time, and only now I started to discover these amazing titles. Too bad that Saturn’s architecture is so hard to emulate. Beetle is great in terms of accuracy, but not in terms of performance. For fluid gaming I prefer YabaSanshiro. Yet one day I’d like to earn some retroachievements in Saturn games, so it leaves me with Beetle (unless Yabause gets a fix for that yellow screen bug).
Right now I just settle for a casual play of Nights into Dreams. The first levels are so relaxing

We were probably born in the same generation. Back in the day the situation was exactly the same as you said in your country. I’m from China and now living in Paris. In late 80’s and early 90’s. Not so many people could afford a video game console. I could just go somebody’s house to play the games. Poor little me… 
I played a lot NES, Game boy and Sega Genesis and some game cube games. Barely touched SFC, Game gear or Nec PC engine, because they are kind of rare and pretty hard to get. And then we have SS and PS. I would never forget how I was shocked when I saw the 3D graphics for the first time. Literally shit my pants. But I just love SS much more than I do to the PS. Talk about the Nights into Dreams. That game was just fucking stunning!!! I started messing with the emulators about 20 yeas ago. Due to the computer’s low performance. We can get them working but still far from being perfect. but look at the emulators today… holy shit.
Now I’m doing the game collection. This a little corner of my collection.the SS section 
! That Nights into Dreams bundle is one of the best things I’ve ever had. I can’t love that round big controller more!
By the way. Even today I still consider the controller of SS the best ever. Just soooooooo comfortable to hold

Wow, I love your collection. I can see some Die Hard in there. I played that one to death on an arcade machine at my school’s caffeteria. The other machine was Metal Slug (2 or 3). Good times.
I live in Poland, which was on the wrong side of the iron curtain until ~1990. Then things started to change, but it took another 6-10 years until home consoles got popular. Until then it was mainly home computers such as Atari ST, Commodore 64, Amiga and PC. But we had quite a lot of arcade machines in the 90s. Lots of money went into Aliens vs Predator and Punisher, and later Virtua Fighter, Tekken and other fighters. I remember visiting London as a high school student in early 2000s and getting into one multi-storey arcade center (I believe this was what remained of Sega World). Man, this was such a heavenly experience for my young, unprepared mind
I think emulation is the holy grail of gaming, both in terms of preservation and catching up with classics for people like me. And it only gets better with technology advances and projects like Retroarch. It’s insane that there is already a working PS4 emulator out there 
I still have a lot of catching up to do from 8- and 16-bit era, and this lead me to totally ignoring current titles. So, when I finally play all the classics from 80s and 90s, I’d have to catch up with 2010s and 2020s
But of course it’s not really about catching up, but having fun along the way. This is what really matters.

Just wanted to say thanks to yuanye8425 for this workaround. I was banging my head trying to figure out why the rom wouldnt launch. Works fine on pc, ra32, bios checks out and nothing of interest in the log file. Tried this and got it to work.
Interestingly, Sega Rally was around 45 fps on my phone in ra32, but runs full speed in ra64. Samsung S20+, SD865 btw.
And now Yabause core is also fixed 
Big thanks to any dev who worked on this. This is really appreciated.
So now we have 3 fully working Saturn cores on Android!
I love being spoilt for choice
