It's the CPU revision difference that caused this console to have the concerto run properly or not. Both CPU's are in perfect working order but only one of them is willing to play nice with the Concerto. Image attached.     I also doubled checked the SRAM sitiation (Hitachi VS Sony at the same speed) and it made no difference, both sets of SRAM worked as they should. The CPU was the only deciding factor with this console.
