> I have a PAL SNES and a PAL Wildcard. I want to be able to play every game in 60Hz-mode so I plan on installing a 50/60Hz-switch on my SNES but leave the lockout chip intact. The reasoning behind this:
> - I assume that if I download and play an NTSC-game it will still use the PAL lockout chip in the Wildcard. It should mean that I would still be able to play games that require the lockout chip to be intact (like MarioRPG). Is this correct?
Not really. Games which (until I figure out how to make an adapter, "watch this space") require a working lockout chip in the console seem to be those which use the SA-1 chip, and maybe others (PAL Super Street Fighter II Turbo????).
There is no PAL version of Mario RPG in particular, so you -- without a suitable adapter -- will not be able to play that, lockout chip disabled or not.
> - The 50/60Hz switch enables me to play any game at 60Hz and I assume it should still work with my PAL Wildcard. Is this correct?
Almost all US/Japanese games will work at 60Hz, unsurprisingly.
There are a few PAL games which do not like being run at 60Hz. From memory, Super Mario World and Mario All-Stars are two of them. There's not much you can do about that, just play the NTSC versions instead.
> Any other aspects to this that I haven't thought of?
Yes. If you have any NTSC carts which don't work through the SWC, it is more convenient to disable the lockout chip. But that is not a big deal really, you could always use a universal adapter/converter instead.
