CPU
The Replica 1 normally comes with a 6502 CPU. The newer 65C02 can be used, however there is no benefit and the newer OpCodes will not be used unless the user calls them directly. This however is not "standard" and other 02 compatible software would not use the C02.
There were some bugs fixes in the C02 CPU. Software could be written that exploited these bugs in the old CPU, however none is known. All the known Apple 1 software should work find on the C02 CPU.
To identify which CPU you have installed on your Replica 1 look at U1 located on the lower left of the PCB. If the letter "C" is in the middle of the part number then it's a 65C02 CPU and not a 6502 CPU.
