drtechnolust Posted November 27, 2016 Share Posted November 27, 2016 I'm unable to launch Colecovision through launchbox using the Retroarch Mame core. Retroarch loads up to an all black screen. I am able to load the core and rom files directly from retroarch though, but not from within Launchbox. Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted November 27, 2016 Share Posted November 27, 2016 Loading console games through the Mame core in Retroarch is very tricky and not something I recommend. Personally I recommend using stand alone Mess which Brad has done videos for, just not for the Colecovision itself I don't think. It is possible through the Retroarch Mame core but you really have to jump through hoops to make it work. It is not just a simple load rom with the Mame core, there is a lot of specific folder and file creation steps involved. Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted November 27, 2016 Share Posted November 27, 2016 This thread here over on the Retroarch forums is an example of what is needed. While this thread is for the Atari 5200 the very same principles would apply for the Colecovision. https://libretro.com/forums/showthread.php?t=5069&highlight=atari+5200 Quote Link to comment Share on other sites More sharing options...
drtechnolust Posted November 27, 2016 Author Share Posted November 27, 2016 @lordmonk It works using the Mess emulator but I was trying to get a way from using Mess. It also works if I open Retroarch directly and load the core with the rom. It does not work when I try to load it directly from Launchbox.

Lordmonkus Posted November 27, 2016 Share Posted November 27, 2016 If it's working directly through Retroarch for you then you could have something wrong in your emulator command line parameters in Launchbox. Quote Link to comment Share on other sites More sharing options...
drtechnolust Posted November 27, 2016 Author Share Posted November 27, 2016 I don't have anything in the command lines which is probably why it's not loading correctly... I'm not sure if there needs to be a custom command to load the games and if so where would I find the commands to use? Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted November 27, 2016 Share Posted November 27, 2016 Your settings in Launchbox look right and if the game is loading straight through Retroarch it should work in theory. But I have had very little luck with using the Mame core in RA to run stuff outside of arcade games. I have gotten them to work but using that guide I posted from their forums. I just use stand alone Mess for systems like the Colecovision, it's just so much easier. Quote Link to comment Share on other sites More sharing options...

DOS76 Posted November 27, 2016 Share Posted November 27, 2016 Okay I didn't know it was even compatible I just use MAME stand alone for all MESS stuff. Quote Link to comment Share on other sites More sharing options...
SentaiBrad Posted November 27, 2016 Share Posted November 27, 2016 I see the -L and -C commands, but do you have the proper Intellivision MESS/MAME commands after that? Also, do you have a custom config in the config path? If not, then the -C command will also cause more issues as well, unless you have the custom config you are trying to load. Should be "intv -cart" after the whole -C command, without the quotes. You can also try intv2. It also looks like Intellivision has BIOS. For the MAE / MESS Core, you need to put the BIOS in a more specific place. Depending on the command you use, create a "intv" or "intv2" folder inside of your ../RetroArch/System/ folder. Then drop the "intv.zip" BIOS in that folder. If you have a MAME Rom set from at least .174 onward, most (if not all) Software list BIOS are in the full MAME Rom pack.

DOS76 Posted November 27, 2016 Share Posted November 27, 2016 I think intellivison has multiple bios files that are needed. Quote Link to comment Share on other sites More sharing options...
SentaiBrad Posted November 27, 2016 Share Posted November 27, 2016 I think that is it, but I am unsure. Also, I think I got turned around here, but wasn't the op asking for Colecovision? Apply the same steps as above, but replace the folder name with coleco, and the command line should be coleco -cart. Quote Link to comment Share on other sites More sharing options...

I have all the bios in the correct location if not then I wouldn't be able to open Retroarch load the core and game without error. Quote Link to comment Share on other sites More sharing options...
SentaiBrad Posted November 28, 2016 Share Posted November 28, 2016 Yea, right after the -L command should be that command, but I don't know why it's not working. It's more straight forward, Ironically, with MESS. Quote Link to comment Share on other sites More sharing options...

As instructed in the RetroArchRoot\info\bluemsx_libretro.info file, the libretro port of blueMSX requires the BIOS files from full standalone package inside the System\Machines directory and media database files into System\Databases directory. There is also some good information about button mapping in that info file. Quote Link to comment Share on other sites More sharing options...
