Libretro Intellivision Emulator

[mitu]

@jeepfan1973 Copy the file to your home folder (/home/pi) first, then execute from the terminal

sudo cp freeintv_libretro.so /opt/retropie/libretrocores/lr-freeintv

[jeepfan1973]

@mitu I put the file in /home/pi/RetroPie/BIOS because I used samba to get it onto the pi from my PC. In trying to copy it from there, I get permission denied in the terminal. Everything is spelled and capitalized and all that where it needs to be. I just don't have permission.

[jeepfan1973]

Ok got it. I was missing sudo in terminal. I was trying to use mc file manager. Thanks!

[jeepfan1973]

However, now when I try to launch intellivision games, the raspi gives a permission error, I think for one of the cfg files. It flashes pretty fast on the screen. Do I have to do the chmod permission for the cfg files that I installed?

Yes. I'll update the instructions to reflect that.

[jeepfan1973]

Thank you!

[jeepfan1973]

Got files copied. Changed permissions for both. It won't launch the games. Just about ready to give up and use jzintv. I was really hoping for an lr core for this. Can't it be added to the retropie package manager?

It flashes an error parsing xml file message:
lv10:. Error parsing xml file /home/pi/.emulationstation/gamelists/atarilynx/gamelists.xml
No document element found.

Don't ask me what Atari lynx has to do with anything.

[recompile]

@jeepfan1973 Now that's a mystery.

Don't ask me what Atari lynx has to do with anything.

The Lynx shouldn't enter in to this at all. Why ES is even doing that when you try to launch a game is completely beyond me.

Something as gone horrible wrong. Maybe someone with more ES knowledge would have some idea as to what actually happened. I can't even begin to guess.

The only thing I can suggest is to the install process over from the beginning (having sort-of done it once, it should only take you a few minutes).

[jeepfan1973]

I tried to delete the files I installed but I don't have permission to do that either.

I
give
up.

Call me when there is a package I can install from the retropie menu.

Right now this core is still in the early stages of public release. Give it a month or two and things may be quite a bit easier.

@recompile I was looking to implement on my system and I noticed that the file emulators.cfg in the download from sourceforge refers to a config file --config /opt/retropie/configs/j2me/retroarch.cfg. I presume it should be intellivision, and not j2me. The documentation file retropie.txt has the correct entry.

@jeepfan1973 In the file /opt/retropie/configs/intellivision/emulators.cfg, check that you have the following entry, with no mention of j2me:

lr-freeintv = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-freeintv/freeintv_libretro.so --config /opt/retropie/configs/intellivision/retroarch.cfg %ROM%"

[jeepfan1973]

That is exactly what I have. Thank you all for your help. I will just wait for the auto installer package. Other priorities right now.

For those looking for a few games to try out with FreeIntv, I've contributed a list with sources for open and freeware Intellivision ROMs to this resource thread: https://retropie.org.uk/forum/post/129594

I just set this up on my pi3. The instructions were very easy to follow for someone who is still learning. Thank you so much to everyone who was a part of making freeintv available! It works fantastic and saves me from having to mess with jzintv. Thanks again!

[quicksilver]

Looks like I found a bug already :(

Playing biplanes on triple action, I can fly right into the ground without crashing, it just loops me back up to the top of the screen instead and then the planes guns get glitched out and you can't see the bullets shooting anymore.

Edit: also noticed that there is a slight audio crackling/buzzing noise while the emulator is running certain games. If I pause the game the crackling goes away. It is only happening with freeintv.

[recompile]

@quicksilver the sound crackling issue has been fixed. I'm still working on biplanes.

[quicksilver]

@recompile you are the man!

Once biplanes is fixed how do I go about updating to the latest version? Do I just manually replace the core?

Also if I find more bugs do you prefer I post them here or on the GitHub page?

[recompile]

@quicksilver Victory! You now crash in to the ground on biplanes. Well, I do anyway. I'm pretty bad at that game.

Thanks again for the helpful bug reports. You can post them here or github. I'm really not sure which one is better. I get an email when they're posted on github, but here puts a little public pressure on me :)

Ed: All you need to do to use the new version is update the core. Just copy freeintv_libretro.so to /opt/retropie/libretrocores/lr-freeintv/

sudo cp freeintv_libretro.so /opt/retropie/libretrocores/lr-freeintv/

If you have trouble building it, I've just updated the release on sourceforge which has a precompiled binary for the Raspberry Pi 3

[quicksilver]

@recompile just tested it out. The crackling noise is gone which is great. However, it seems like biplanes is only partially fixed. I hate to be a nit picker, but my plane can completely intersect the ground and then the crash happens underground. I can even fly completely underground and then pull up without crashing sometimes. I very much appreciate your hard work on this so I hope you don't mind the feedback.

[recompile]

@quicksilver No worries. I have a pretty good idea of what is causing thatproblem . If I'm right, the fix is simple, I just don't like it. Give me a few minutes and I'll check.
