doug0909 Posted July 23, 2018 Share Posted July 23, 2018 If you have an android phone, you can play full speed O2 through the Retroarch emulator (I didn't find the discontinued Videopac emulator, or running O2em through DosBox, to work very well). Just download the O2 core and put the system roms in the system folder. I played Attack of the Timelord and JG Munchkin at full speed; I'm playing on my V20 phone with a bluetooth wrap around controller. Demon Attack also works great (except for the bug in O2EM which sometimes messes with collision detection). The KC games played decently, but for some weird reason Pick Axe Pete alone demonstrated slow down. Turtles ran fine, though I had trouble making the precisely timed turns with my bluetooth gamepad.The biggest problem - it won't switch to the other joystick for UFO, Alien Invaders, etc. I tried every controller setting, nothing so far... 1 Quote Link to comment Share on other sites More sharing options...
Flojomojo Posted July 23, 2018 Share Posted July 23, 2018 I wonder if someone can hack UFO so it uses the left stick like every other 1P game? 1 Quote Link to comment Share on other sites More sharing options...
doug0909 Posted July 24, 2018 Author Share Posted July 24, 2018 Good news... Just set up a configuration file with this in it, with the same name as the .bin (ie ufo.cfg for ufo.bin) and all the right handed games will work with your Bluetooth controller... input_player1_joypad_index = "1" input_player2_joypad_index = "0" 1 Quote Link to comment Share on other sites More sharing options...

Especially since it's so easy! I don't have an Android phone, but I might need to put RetroArch on my Kindle Fire now. Quote Link to comment Share on other sites More sharing options...

UHATEIT Posted July 24, 2018 Share Posted July 24, 2018 Wow that's pretty sweet! I had wondered how you would get the inputs to work on it. I have the Odyssey disc burned for the Dreamcast and you have to press some random buttons to get anything to move at all. I'd love to try this on the retroarch app on my phone. I use the app to play Lynx and Virtual Boy on my phone. Quote Link to comment Share on other sites More sharing options...
doug0909 Posted July 25, 2018 Author Share Posted July 25, 2018 You don't really have to do anything for the inputs if the game uses left joystick... This thing also has a pretty nice vectrex emulator... Quote Link to comment Share on other sites More sharing options...
UHATEIT Posted July 25, 2018 Share Posted July 25, 2018 I downloaded a rom set and unzipped it but it still isnt loading the roms with the emulator from retroarch. I'll have to keep messing with it. Quote Link to comment Share on other sites More sharing options...
doug0909 Posted July 25, 2018 Author Share Posted July 25, 2018 You need to add the O2 bios files to the system folder Quote Link to comment Share on other sites More sharing options...
doug0909 Posted July 26, 2018 Author Share Posted July 26, 2018 I can't get the Voice to work using the sound samples in a voice folder if anyone can figure that out... I tried placing the voice folder just about everywhere.... Quote Link to comment Share on other sites More sharing options...
UHATEIT Posted July 26, 2018 Share Posted July 26, 2018 I am a little lost on the bios in the folder part. I downloaded a whole romset and then unzipped everything and they are all in the same folder, but when i hit the Odyssey emulator and then load content and go to the folder and select the rom it says failed to load. I have tried clicking the bios as well and it says failed to load as well. All are in the same folder tho. I tried it with all the roms in a folder on the phones internal storage and then since they are all small put it on another folder on the SD card and both are unzipped and neither will load with the emulator.

doug0909 Posted July 26, 2018 Author Share Posted July 26, 2018 Just put o2rom.bin in the System subfolder under the Retroarch folder. Quote Link to comment Share on other sites More sharing options...
UHATEIT Posted September 6, 2018 Share Posted September 6, 2018 I am likely just an idiot or doing something wrong but I have downloaded an entire romset, found the bios called o2rom.bin and downloaded the Odyssey emulator on retroarch on my phone and anytime I click any of the roms it said in yellow "gfailed to load content". I plugged my phone into my laptop and then found the Retroarch folder, clicked it and there is one called Systems, so I opened it and it was blank, I put the bios o2rom.bin in that folder and then tried loading the games from the phone and still says "failed to load" am I missing something in those steps?

doug0909 Posted September 6, 2018 Author Share Posted September 6, 2018 Other than the subfolder being system, not systems, nope. Are your roms still zipped? Quote Link to comment Share on other sites More sharing options...
Flojomojo Posted September 6, 2018 Share Posted September 6, 2018 Maybe force quit the app and make it reload cold? I agree that it sounds like everything should be in the right place. Make sure you're in the correct System folder, there should be one for each core as I recall. Quote Link to comment Share on other sites More sharing options...
doug0909 Posted September 6, 2018 Author Share Posted September 6, 2018 I hate to say it, but maybe your phone doesn't have the raw horsepower to handle the graphic and auditory brilliance of the Odyssey 2. Remember, according to the marketing materials, it was years ahead of its time and using space age technology to create true sync-sound action far beyond what you could find in a video arcade! You might want to stop in to your mobile phone store and ask if they have something more powerful, maybe a Note 9 with 256gb ... Quote Link to comment Share on other sites More sharing options...
UHATEIT Posted September 6, 2018 Share Posted September 6, 2018 Other than the subfolder being system, not systems, nope. Are your roms still zipped? it is "system" but there are no other folders inside of it, it's blank, none of the cores are there but I added the BIOS in there and then all roms both unzipped and zipped to that same system folder and its the same "failed to load" I don;t have any issues with Sega Game Gear, Lynx, Virtual Boy, or jaguar. Just the Odyssey one not wanting to load. Quote Link to comment Share on other sites More sharing options...
doug0909 Posted September 6, 2018 Author Share Posted September 6, 2018 Why did you put the game roms in the same folder as the system rom? Try changing that... Quote Link to comment Share on other sites More sharing options...
UHATEIT Posted September 6, 2018 Share Posted September 6, 2018 I added them to the system folder when it wouldn't work in 2 other folders (one on the internal phone storage and the other on the SD card storage) Weird thing is the Retroarch folder itself is fairly basic on the phone, there aren't any "core" folders to show what cores were downloaded for me to see what is inside of them. Again this is odd since all the other systems I have tried on it work just fine. Quote Link to comment Share on other sites More sharing options...

Flojomojo Posted September 6, 2018 Share Posted September 6, 2018 You've got the O2EM core installed, right? It's been a long time since I've played with it, but I had to get Android Retroarch from the nightlies rather than the Play Store when I was last messing with it. http://buildbot.libretro.com/stable/1.7.3/ Quote Link to comment Share on other sites More sharing options...

Flojomojo Posted September 6, 2018 Share Posted September 6, 2018 I still think it's his processor. Can you overclock that thing? True, true -- 1.79 MHz is a real powerhouse. It could also be RAM, the Odyssey 2 had 64 bytes of CPU-internal RAM and 128 bytes of audio-visual RAM, in addition to the 1024 bytes of the BIOS ROM. Better get some cooling on that thing, it's moving a lot of data! 1 Quote Link to comment Share on other sites More sharing options...

I have Retroarch + Odissey 2 Bios + Odissey ROMs running in 3 different setups: - RetroArch for Windows running on PC / Windows 7 - RetroArch for Android TV running on Nvidia Shield - RetroArch for Android TV running on Sony Android Smart TV. I failed to get games that require left-joystick to work with right-joystick-only in all 3 different setups described above. For games that work directly with the right-joystick, I have my Odissey 2 emulation running smoth. Thanks a lot for the information !
