SNES TSOP burnt chip problems

I use a 29F033C with a DIP36-TSOP40 Adapter (III).
When i put
the game into the SNES, it worked for a couple of seconds and showed the Squaresoft logo, then it failed.
It gave a burnt smell, and when i look at the 29F033C chip, i can see that pins 29 VSS, 30 VSS, 31 VCC are burnt.

I have bridged R1 and R3 on the adapter board.

Does anyone have a clue what i am doing wrong?

PCB

Pins 21-40

Hi,

29 and 30 are VSS = GND: You could solder a bride and Connect a cable to the GND Point 18. Close the third jumper and try again.

The pin 31 is vcc and should work. If the connect is broken, you should got only a black screen.

Maybe, you have a broken solderpad. Please resolder all connections on the backside of the pcb.

thanks

Hi and thank you for your response!

It seemed to work for a couple of seconds, but then it turned black and i smelled the burnt chip.
I will try that to connect VSS to GND pin later and see if that works, and also close R2
