@grant2258 it's the built-in controller for the Retroflag GPi case (http://retroflag.com/GPi-CASE.html) - i think it's connected like a USB gamepad, though i'm not sure. thanks

I was able to get jzintv installed and running. The only problem I have now is I can't get it to display with a 4:3 ratio. I have used the below configuration file on my Raspberry Pi 3 and it works great. If I launch Emulation Station from the Buster Desktop, then jzintv will display the correct 4:3 ratio in a window. However if I exit out of Buster and run Emulationstation by itself, jzintv will automatically stretch to fill the screen. I've tried making display adjustments in Retroarch, but it doesn't seem to affect it. Other emulators like Stella, Nestopia, and a few others, maintain the 4:3 ratio automatically. Just wondering if anyone else has seen this problem with jzintv or some other emulators? jzintv = "/opt/retropie/emulators/jzintv/bin/jzintv -p /home/pi/RetroPie/BIOS --gfx-palette=/home/pi/RetroPie/roms/intellivision/composite_colors.gfx -z1430x1070,8 -b10 -q -v1 -s0 --kbdhackfile=/home/pi/RetroPie/roms/intellivision/hackfile.cfg %ROM%" default = "jzintv"

@SpudsMcToole Just out of curiosity, which es_systems.cfg do you edit? I always copy the original to /opt/retropie/configs/all/emulationstation and edit it there where it won't get reverted when running updates. Only thing is it also has to be manually updated/synced if additional systems are added as they won't show on the system list if not listed in the customized es_systems.cfg (I'll normally copy-paste from the original file to the copy once the new system is installed). It just saves some of the headache for the future if you have a custom system order you like and don't want to redo it after updating.

Two things. First...coming from someone who never had Coleco...This thing is so graphically superior to Atari its disgusting. Second...I figured it out by playing around with it. If you have a PS3 controller just copy paste this into the CoolCV Mapping file on the pie. If you dont like something on it just tweak but it works.

@Nightfire Just noticed your question been a while., but I have to do this in my gpi case. Controls Joystick axis Should just work joystick_1_vert joy0 axis1 joystick_1_horiz joy0 axis0 In Game Buttons left_button_1 key32 joy0_1 right_button_1 key109 joy0_0 Start Buttons Colecovision has a numeric keypad to start game 1-9. Also *, 0 and # Key. This is where jsTest comes in handy. The # from jsTest should be appended to joy0_ key1_1 key49 joy0_7 key2_1 key50 joy0_6 key3_1 key51 joy0_3 key4_1 key52 joy0_2 key5_1 key53 joy0_4 key6_1 key54 joy0_5 key7_1 key55 key8_1 key56 key9_1 key57 key*_1 key111 key0_1 key48 key#_1 key112 key_save key1073741882 joy0_6 joy0_5 key_restore key1073741883 joy0_6 joy0_4 key_exit key1073741939 joy0_6 joy0_7 key_pause key1073741884 key_reset key8 key_screenshot key1073741891 https://sites.google.com/site/gregsqna/gaming/handhelds/retroflaggpi/emu/colecovision

Hi, i solved in inverting RIGHT and LEFT Gpio cables ans calibrated under Emulstation. Bye

@hurricanefan @herb_fargus i updated retropie setup and coolcv and the audio is fine. @HurricaneFan can you press start in emulationstation and go into sound settings and verify the volume is at 100% and not 77% ? Some coleco games arent very loud in the first place.

@mediamogul the flashback ones came in two small ziplock baggies. Then i put my homebrew ones in a small ziplock baggie as well.

@alortegac my coleco.rom is in /opt/retropie/configs/rom/coleco/ . I dont have one in bios. Try putting it there and give it 0777 permissions. I think it is an advmess/mame location but thats where i have it. I am doing a search to try to find any other locations i have it in.

@mediamogul It's all good, just got a little excited to add another system, no big deal, just always looking!

@SpudsMcToole just for the record even if it was a bug with coolcv there is nothing we can do about it as it's closed source. You may have luck getting a hold of Oscar the developer (nanochess) on the Atariage thread , possible someone else may have had the same issue and posted a fix. I haven't been over there in a while so idk

@Shizzmoney you don't need to copy it to add extensions. Just create a file /opt/retropie/configs/all/platforms.cfg with a line fds_exts=".nes .fds .zip" (with your extensions and update the emulator in question. If we have a missing extension though it should be reported back to me :-)

@Rion I have yet to find a solution to properly handle colecovision inputs in fbalpha-libretro (colecovision's controller got 14 buttons, libretro's retropad only have 12 if i include start/select/R3/L3). I also heard 2,4,6,8 buttons were actually a second d-pad and 5,7,9,0 a third d-pad, is that true for all games ? If it is, i could probably map those to the analog sticks, and map the 6 remaining to actual buttons (# as start, * as select, the last 4 as A/B/X/Y).

@herb_fargus I did not know that. To bad about the input would love some bezel and shader support.
