My first job was port from PS1 -> PC, then next project was another game, but this time port PC -> PS1 - we never got this kit (it was small studio of 4 people). We used (what I think was) the Yaroze... "printf" debugging all the way :) (oh, and when you remove the "printf" things were not working - lol, because printf() kept on clearing math errors, and our PC game was floating point heavy). TLDR: First port (PS1->PC) went really well, second one - we were able to get to the 2nd worst game done for PS1. (back then).
