It started just a few weeks ago
I was testing one of my homemade multicartridge which suddenly the color of the game turned into black and white!
I thought bad circuit of multicartridge caused the issue
I just admit it that I messed up with GPU which is inside of the CPU!
After fixing the Multicartridge it ran just fine but with no color
I noticed that it freezes randomly!
Then I thought it is again because of a bad cartridge and I tried adding some caps to it without no luck!
Yesterday I wanted to play a little with my Famiclone and I found out that it freezes very often with any cartridge!
I start searching for any unusual thing on the board
I found out that all the problem was because of the crystal loose pins which was caused by pressing eject button :
So as a result a loose pin of the crystal can cause black and white color with random freeze!
