I did the same while in high school. Someone asked me to mod his PS1 so I copied the pic12c508 he provided to me so I could do it again for cheaper. For the sales, it was actually a rather good business, I had between 1 and 3 console a week to mod, for almost a year, and I didn't even put an ad. It ended because someone with the latest model (SCPH 8xxx if memory serves) inisted I try to mod his PS1 despite me not having proper equipement to solder at the needed accuracy. It did failed obviously. I had a hard time making it work again, it was so stressful that I ended up stopping it altogether except 2 or 3 times after that for some close friends.
