I pulled my old Playstation 1 out of the closet, just to try this swap trick I've seen on youtube, but no matter how many tries I can't seem to get it to work. I have the sensor button taped down, but I think my problem is the timing. I have an original disc (Twisted Metal 4) and a perfectly burned backup of Castlevania Symphony of the Night but I've tried swapping like 30 times and I just can't seem to do it. Some YouTube videos I've seen are confusing me because I see people taking it out at different times and stuff. Can anyone give me some concrete help on this?
