I dont know if anyone already did it ... there is already publicated TASes that uses 2 games at once using same input... I noticed all were from same console... So, how about doing the same but with 2 differrent consoles? EG: Snes+Gen... since many genesis game have on snes it may should be funny to watch 2 almost exactly games on different consoles to watch, for example, The Lion kING on genesis and snes, they have almost exactly gameplay and graphic design, but arent exactly equal on somes aspects, so a gameplay like that could show the differences between gameplays even the games being almost the same... so, what u guyz think?
My main objective here is to TAS the most obscure games titles!

These different consoles use different controllers. There is no "same input" that can be applied. Unless you take the largest common denominator of both controllers, but then you're going for a special case which is kind of artificial.

Perhaps a NES+GB game could work, since they have identical controller buttons.

GBx TAS of 2008
NES and GG/SMS would also work, as long as you're ok with A=1 and B=2

Then again, 1 input on multiple emulators is impossible because all movie files are structured differently.

True, though you could make a lua script that performs the input on both consoles (you would only need to change the frame advance line in the lua code).

Frame speeds aren't the same on all consoles. And the Game Boy really has no concept of frames anyway, since the game can turn off the screen, then turn it back on at any time.

Frame speeds mean nothing. The input would be the same for each sequential frame, regardless of the actual frame rate, all this means is that the encode would either have the button inputs gradually desync or one of the games has the frame rate and audio sample rate adjusted.

I'm pretty sure you can interchange Megadrive and Master System controllers, too, since they have the same plug. Obviously games won't always work right since they have different numbers of buttons, but lots of them probably do.

GB Megaman and NES Megaman games might be fun to watch. Both systems are on the same processor too.

MrTickles, the only similarities between the Game Boy and NES are the sound system... and even then, there is substantial differences. They don't even share the same CPU architecture, if anything, the Game Boy has much more to do with the Game Gear, Master System, or Mega Drive!

In terms of input button mapping, the DS and SNES have the same buttons if you don't count the DS's microphone, lid switch, or touchscreen. (And there are plenty of DS games that don't really use any of those.) Probably the best rule for runs designed to synch on two entirely different systems would be to give another input every time the system in question polled input (normally, but not always, once per frame, sometimes not counting lag frames). Presumably you'd have to scale the speed of the videos to match so that the similarity in input became obvious.

Spirou might be a neat proof of concept. Look at this:
