Hey, guys! I've recently been hunting some Genesis/MD games I always liked but never owned in physical form, and now that I'm actively looking for cartridges I noticed that the PAL versions of some games are much easier to find or simply cheaper than their NTSC counterparts. I lived in Brazil my entire life, so my consoles are either NTSC (1 Genesis and 1 Japanese Mega Drive) or PAL-M (1 Tec Toy Mega Drive, which AFAIK works exactly like an US Genesis as far as games are concerned), meaning that region-locked PAL games are gonna be a problem. Since I'm kind of a purist and don't really want to mod any consoles to add region/frequency switches, I decided to buy one of those Mega Key thingies, in hopes of having complete freedom to run any game I want on any of my consoles. What I failed to realize was that the Mega Key I bought doesn't specify a dip switch setting for PAL games on its label, presumably because it was sold in PAL territories, where most people would have no use for that setting. Anyway, since the thing has the same number of switches as the other Mega Key versions that are known to work with PAL games, I'm wondering if it can still do all the configurations, and they just didn't write that specific one on the label. Does anyone know if that's the case? I compared my Mega Key to other versions and it doesn't look like the dip switch configurations that are listed match those of any other version, so I don't think I can simply use the information printed on any of them as reference for the PAL setting on mine. It would be great if I knew what each switch actually does, so I could try different settings without being afraid of frying anything. Does anyone know how these devices work and what the switches actually do? Would it be safe for the hardware (console, game and the Mega Key itself) if I tried unlisted configurations one by one? I've attached a photo of the adapter I bought. Any information you guys can contribute will be greatly appreciated! BTW, I have no idea why these adapters have a setting for Brazil specifically... I was always under the impression that Brazilian consoles and games were just like the US ones, the only difference being that the Tec Toy consoles output PAL-M video (which is 60Hz just like NTSC).
