Any difference between PC Engine models? You know, the white one and the Coregrafx? Just wondering

The only differences between the original PCE and a Core Grafx is that the Core Grafx is black and says "Core Grafx" and that it has AV output. The only difference between Core Grafx and Core Grafx II is that Core Grafx II has orange text instead of blue. The difference between the PCE and the PC Engine Shuttle is that the the PC Engine Shuttle has a spaceship-like design and doesn't have an extension in the back, which means it can't be hooked into the CD interface. The list is pretty long.

Here's the scoop:

1. Original classic white PCE = RF out

2. CoreGrafx = A/V out replaces RF out.

3. CoreGrafx II = Cosmetic color change.

4. PCE Shuttle = eliminates the expansion port in the back, so do NOT buy this if you ever want to get the Japanese "TurboBooster Plus" (battery memory back-up) or upgrade to CD-ROM.

apparently shuttle does have pins at the back so provided you have suitable part it can be mod'd for the port...
