My notes:
*BOTH the Arcade Card Pro and Arcade Card Duo will work on all Duo systems and the Super CD-ROM2. The Arcade Card Duo will NOT work on the original CD-ROM2. It requires an Arcade Card Pro for Arcade CD-ROM2 games.
**The Lazeractive will accept PACs from any region, regardless of where you got it. The PACs, as mentioned above, are not region free. The PC Engine PAC will not accept Turbografx-16 games unless it is region modded.
***The GT/Express and original Duo (both PCE and Turbo) sometimes have capacitors that leak, which will mainly affect the volume of the sound coming out of the systems. They can be replaced. If you need this done, some members of PCEngineFX.com do this for a reasonable fee. I have not heard of the other systems having this issue aside from Apolloboy mentioning it in this thread, but it is certainly possible as these consoles age.
****The original CD-ROM2 has a plastic gear inside that is of poor quality. It eventually turns a yellow colour (SNES yellowing-like. I have seen it) and eventually disintegrates. Of course, some of the guys at PCEngineFX have found a way to replace it. I personally cannot remember what it is.
*****All PC Engine HuCards work on the Super Grafx. There are five Super Grafx games that are ONLY playable on the Super Grafx. There are two PC Engine games that have enhanced graphics on it (less flicker and parallax backgrounds).
******The original PC Engine is cute and sexy. Consider replacing your girlfriend with it. If you are married, then... you know what is best already.
