what about switching to a very small looping silence ? this will give the illusion of no sound

ok ill look for those when im able. in the meantime i sourced a cartridge connector 3d model, unfrtunately its not the right colour's, but i guess you cant have everything ENG_CVM_CVM_5530841-2_B.3d_stp.zip datasheet: https://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=5530841&DocType=Customer+Drawing&DocLang=English mfg's part number: 5530841-2

im not too sure what you need here, are we consentrting on the yellow outlines or the non yellowd components? i can see an issue with the picture already however, some of the transistors near the rgb out socket have verticle resistors on some of the transistor base pins, this is not highlighted as having anything so that will need documenting. i wont have access to my scart colecovision for 1.5 weeks but after that i should be able to do something if i know what is needed

i may be able to help with that if interested, i do have a pal / pal scart / ntsc board so i can provide reference, i also dont mind removing the odd component if the wording is under a chip or whatnot to find out the correct references

@ChildOfCvjust some general feedback based upon your shared project folder with the schematics and whatnot. There appears to be some errors with the PAL SCART board project, there seems to be multiple R180's and R181's also the pcb layout is for a NTSC Coleco, i did try importing a new netlist but errored because of the multiple resistors. i did try and fix that by giving them some name appendages but it gave me more issues after, so gave up. this is only because i spent most of the week trying to self learn kicad which i have learnt a lot but there's still a lot missing like multiple schematics and hierarchy etc thought i would have a play with a more complex project than my own one sheet jaguar joypad to coleco joypad converter project, which is coming along quite well now

you mean like this

i would be happy with a 6 pin icsp header, then it can be flashed with a cheap arduino uno clone and avrdude

Having repaired multiple colecovisions for me and a friend this would be something I would buy for sure, previously I have replaced chips until I found the correct one which is a pain If you do decide to sell any I will be purchasing provided it deals with both pal and ntsc I do have a secam machine that has some issues with video (jail bars displayed when the system warms up) that i havent tracked down unfortunately, this possibly would help

i believe this was a quick bodge help while i was at work from what i recall so couldn't do any descent research this should be a better answer to the correct point, i may of got the side mixed up when i drew the line

that was what i got vimaster to make for me and the other speedster label above too, he decided to release it for everyone after, which of course was up to him

i cant remember exactly what the buttons are, but from what i can remember when i played it last is that player one joypad is movement, and player 2 joypad is fire

nope, you need to use both controllers for a single player game

you do realise thtat to play skycopter properly you need 2 control pads and use both of them simultaneously dont you

just found this thread, and am interested in acquireing it, there doesnt seem to be any PCBs available. is that something that will be produced again? if this is not correct where can the PCBs for these be purchased?

liking the schematics, you seem to know a great deal of kicad. i am dabbling with it but i think this level of greatness is far beyond me currently i did notice that the coleco scart board pcb appeared to be the NTSC consol version and not the french secam version though. not sure what happened there?

for those not aware there are a great number of indeviduals (including me) that are actively working to preserve this systems games. for those interested, check this out: https://ouya.world/t/how-to-bypass-account-login-firmware-update-page/15 https://www.s-config.com/root-the-ouya-google-play/ https://cweiske.de/tagebuch/ouya-purchases.htm http://ouya.cweiske.de/ https://discord.gg/tF9B4v

does anyone have any 3d models of a colecovision cartridge shell they wouldnt mind uploading. the end goal of mine is to 3d print a couple off to house a few of the available games that have been posted for download. they would need to be in an editable format like inventor or step because they would neeed to be modded a little to accept the non standard circuit boards i posess

got something in the inbox today CVSD_Upgrade_Instructions_Beta_2.zip have fun

i expect the person spreading these lies IS or is closely tied to the one very well known spew spitter the we all hate

has anyone managed to get hold of the latest update from Steven yet? if so can they post the firmware here i emailed him like we are supposed to but it has been over a week now and nothing. he is a hard man to get hold of! thanks

can you upload the file here by chance?

this is still proably the latest CVSD_Upgrade_Instructions_Beta.zip

LOL! Well, theres the problem right there

by the look of that, it is my beleif that the rom chip which is can hold 128k (for a 32k game) actually hold multiple game rom images, and the pin 13 issue and eur / usa selection pins are wired to address lines, so whatevr is selected +5 or 0 volts it configures the eprom to make available to the console a specific region of romspace which contains the relivant rom image depending on selected criteria. this makes perfect sence to me now by being asked what region i would like the game when purchasing. that being said, i am only assuming by what i see in the cartridge pictures. may i ask where this image came from, there appears to be cropped text around the picture that might be useful / interesting to see.
