Have you tried these carts on another SNES?
Do other games that have a co processor work?
Are you using a NTSC or PAL console and are you using carts from the same region?
Can you post pictures of the board? both the bottom solder side and the pins from the top

Mario RPG and Starfox both use the extra outer pins on the cartridge slot (99% sure). Many game do not use the outer 8 pins.
Make sure those are clean and free of debris, maybe you had a small piece of wire or solder drop in the slot?
Crazy things can happen.
Edit: I see that MrPete1985 suggested the same thing. so nevermind.
I would check and see if there are any solder bridges or anything else that may be making a bridge on the extra pins on of the cart connector.

Any advice?
Hi, what I see on your pictures, the decoder BA6596F have pins not well soldered, specially in the connector side. I recommand you to rework the pins 13, 16, 17, 19,20 and 21. rework all the solder on the side of the connector for the decoder. To verify your solder take a small screwdriver and try to move gently the pin. If the pin move, the solder joint is not good. you can check the pins that I mentionned before with the same method before reworking them.
These pads on the decoder is gone. But have that really something to do with my problem? the thecoder is for the image right?
I am not a specialist of rgb modding, but what I know is that some of the pins I mentionned are critical for video. for example, pin 13 is for the chroma color carrier 3,58mhz. Pin 19 is for the region selection NTSC or pal. So it can be the problem, and you have nothing to loose for trying resolder the pins, or at least verify the contact of the pins with a screwdriver
I think you are right but why do other games work that doesnt use those extra pins?
Also the pads on the motherboard are burnt and gone so i have to rewire fom decoder to other points, but i dont see how the rails goes?

Some of those pins are power. Some of those pins are video. Super Game Boy and most games with special chips used them. Normal games did not need them. Pretty sure that SGB and most FX games used the video pins and, well, they had to power their processors somehow.

But what I can see many of the pins burn out are not connected to anything

It must be the problem then, can it be rewired somehow? becaus some of the pads are gone

I removed the encoder chip completely and as you can see pin (24) (23) (22) and (18) are gone.
Pin 24 is rgb-blue pin 23 is NC 22 is RGB Green and 18 is NCP?

I have a snes mini,I could try and trace where the missing pins go,also here's a pinout of the chip.
Thanks! I would be very greatful for that
