I'm a huge video game fan, and I'm looking to recreate the TurboGrafX myself, from gate level. My issue is that I can't find a free PCB program online, anywhere. Is there something professional I can get a hold of without selling my sole to the devil?
What you're asking for is contradictory. A PCB is a circuit board. A "gate level" design is the internals of a microchip. The software used to design these two things is completely different.
For PCB design, Kicad is a highly capable free tool.
A "gate-level" design is a bit unclear, but would probably refer to either an FPGA or VLSI design. Free software for these workflows is largely nonexistent -- Project Icestorm has some tools targeting Lattice iCE40 FPGAs, but these parts are rather small and are unlikely to support the system you are targeting.
OK, I didn't realize this got transferred from the EE side, so (where I could comment): For a brief historr/background, google "gate level synthesis", you should get a reference to this document from MIT a few hits down (it's a history/background/intro) "IO5_synthesis.pdf" I dont' know if this link will work for you hence the above refs:
