Tested the srm save on my end as well and can confirm it works so it is definitely something wrong with the save states causing an issue in the game. Sucks losing the option to use save states but at least I can play through the game again.

Thank you all for your help.

edit: still happening after I open the retroarch menu to toggle cheats or something, have some ideas I will test and post my findings later

@Everett1954 I was able to get about half the Creativision games working with Advmess. However, I wasn't happy with the results because I couldn't get Planet Defender to work. I wound up manually installing the creatiVision Emulator (Linux Source dated 24 April 2016) (source file: creatiVision-1604240src.7z) from this website: https://sourceforge.net/projects/creativisionemulator/ This emulator uses SDL.

Having unzipped the files into a new build folder, I compiled it with cmake /home/pi/build(using GNU 4.9.2 on my Pi) and make. Once the executable creatiVision file was created, I then set up a layout etc.

All of the games seem to work and appear to work at full speed.

Your mileage might vary. I did this more than a year ago on Jessie, and I'm using Attract Mode, rather than emulationstation, and I also use xboxdrv for controls.

Also my emulators.cfg looks like this:

default = "creatiVision" creatiVision = "/opt/retropie/emulators/creativision/creatiVision -r %ROM% -b /home/pi/RetroPie/roms/crvision2/bioscv.rom -f"

Note the reference to the bios file bioscv.rom.

You may need to adapt the emulators.cfg for emulationstation, but I can't help you there.

@Heartless I'm not overly familiar with their development, and someone correct me if I'm wrong, but I believe the latest version of either runs worse on the Raspberry Pi.

@mitu Alright! Then I will wait until the Scraper problem is fixed. The autostart is already implemented in the retropie programm. Just need to go to the retropie setup and set the autostart option to enable.

My Retropie is now starting automatically. When I quit Retropie, I have my normal Ubuntu Desktop.

Anyways, thanks for the help! I am done for now.

@chubsta Welcome.

It sounds like you'll be able to handle things well.

Message me back if you have any issues. My updates to the setup guide have been somewhat haphazard, but I'm pretty sure everything is right.

I got it to work using 'screen'

sudo apt-get install screen

$ screen -d -m emulationstation

I actually just did something similiar which worked perfectly. I just took an in game video clip with my phone. I installed the Pixel environment. I uploaded it to youtube. Then used youtube2mp3 to convert it to an mp4. I downloaded it to the pi via Pixel. renamed it to the game name-video.mp4. Placed it in the images folder. Then i rebooted and selected the game and edited the meta data with the file path under video. Then saved and exited. Works perfectly. Now i can do that on the other 3 games i do not have videos for and the ones that wont play and i should be golden.

@Azurden I believe you are confusing various uses of the word 'set' and incorrectly equating them. You need ROMs that match your emulator's needs. The easiest way to deal with this is to get yourself a complete collection (a rom set) of MAME 0.78 roms. Individual games are comprised of rom sets as well. Different versions of a game will have different roms comprising them. Missile Command set 1 and set 2 are two different hardware versions of Missile Command.
Get yourself a full collection mame 0.78, copy the games you want over to the roms/arcade folder on your pi, and then use lr-mame2003 as your emulator on the Pi.

Hmm. Now I'm wondering where the setting is for bilinear filtering is located at. EDIT: Found it. Everything is now good. Thank you for the help.

so back again :) what happens to the retropie? once a few month ago it was very very user friendly just install and transfer roms.

now i got a really bad start with the new version 4.4 nothing seems to run anymore.. no kodi ( same problems i got initial with the NES roms ) no other emulators.. all got the same problems.. has there be a change in the versions? or why do i have that problem with the 4.4?

never mind, i fixed it! thanks for help @mitu!!! really appreciate it

@musclebound it's very likely related to vram but as @quicksilver stated, we need a lot more information to even try to point you in the right direction.

In the future please use a descriptive title for your issue per the forum rules. Otherwise we'd just have walls of "please help" on the threads

@mitu Oh ok then. Thank you

@mitu That's what I have been using. The only reason I wanted a libretro core was because my pi would often crash when launching other games/emulators after using Drastic. If there is a way to completely unload Drastic after closing it that would be great but thanks for your help 👍

@mitu Indeed. I have been careful about case. I manage some old school UNIX boxes at work, so I am not unfamiliar with case issues. I am using a keyboard attached directly, not SSH.

Five reboots later, I was just able to get it to work. I have no explanation. (I have parkinson's and typically have a ton of typos, so I am going to just assume user error for now.)

@markyh444
Oh poop, I thought I was on the Kodi forum... My bad!

Thanks mitu! It works!!!!!
