Is there a way of using disabled Bitcoin script opcodes on a local simulated Bitcoin blockchain (without using an old version of the Bitcoin core)? E.g., to test some transactions utilizing OP_CAT in the out script. If this is not possible, the alternative solution would be to switch to Bitcoin Cash, I guess?
