>>11878550The world of consoles is bigger than the PS1, anon. Enthusiasts would be hitting up their local importer long before someone would figure out how to wire up a PIC chip to bypass a region lock. Converting a NES/SNES between PAL/NTSC is not a trivial task and the end result is not 100% correct either. The only consoles with easy mods were the SEGA consoles where SEGA used the same chipset in all regions with a trace or two to denote which mode to work in and rarely put region locks in the carts. So yes, people did in fact import consoles with enough regularity that there were a LOT of hole in the wall video game import shops that did plenty of business selling moonrune and american versions of games alongside the hardware to play them. And when modding became commonplace not only did they not fizzle out, they usually sold modding services, because believe it or not, they'd sell more import copies of games to owners of modded consoles than they would otherwise and this made solid business sense.

The most common problem though was that it may sync and display, but probably the geometry will be all wrong so if you can't access the manual controls for that then you will get a nasty image. But unless your TV had an NTSC decoder you wouldn't get colour, hence the preference among importers for RGB scart that would sidestep the issue entirely. I had a cheap 1990 TV that would manage to get a PAL60 signal off a dreamcast over RF. But it had tremendous coil whine when it did.
