Hello Aaron,
first let thank for reacting on my post!
Now for your questions:
1.) I got my FX 2 months ago and it was used. I got it from a guy I know is collection millions of games and systems. I occasionally buy some stuff from him since one year. The system is just a little bit yellow (sunfaded?). From the ouside I would say it's in good condition and clean.
2.) I also got Zeroigar around christmas last year, even before I even have had my FX. It is used but in very good condition. The package is in great condition. Instruction manual looks like that it isn't used at all and the spine is also included. The CD itself also looks very good, no scratches probably just some minor scratches like you would have on every CD when you get them out of the box.
3.) No other of my other FX games hang. I have about 15 games (My FX User profile will need an update
) and all work perfect. But I discovered that the PC Engine Fax Deluxe Vol.3 (I think it's Volume 3) with Zeroigar playable Demo included also cuts the FMV sequences like the original one.
4.) That's a thing that I haven't tried till now. I'll try it next week when I will have time for it. I only heard that first revision PSXs had this kind of problem with the CD lens which could be fixed when laying the PSX upside down.
I hope that these facts could help. I think it's quite strange that Zeroigar is the only game which has this kind of problems. I also own about 150 PCE CD games and none of it has this kind of problems.
Besides this I hope that probably someone also played Farland Story FX and can help me figuring out how to finish the 5th level. I really want to play further. It's a very decent game in my opinion.
