I'm trying a little project here, even though I don't expect to get too far.
Basically, what I'm attempting to do is replace a rom inside Sonic Mega Collection. I made an ISO using a copy that I own, and I even found a tool that allow me to extract everything out of said ISO (and compile it all back again for use in Dolphin or Nintendont). Once extracted, there's a folder listed as "roms", and all the games can be found in there.
Problem is, they're all in .dat files, and from what I've read over many websites and so-forth, .dat files are apparently tricky because they have such a large range of how they're handled. Even though I have no hard evidence of this, I *think* the .dat files here are just compressed files, as I followed this guy's trick ( http://www.racketboy.com/forum/viewtopic.php?f=52&t=30647 ) and was able to successfully extract the roms out of the code and save them as a file (.bin) that the Genesis emulator could play.
Unfortunately... I've no idea how to actually get into these .dat files and save/replace them with something else. None of the tools I've come across can do it, though I wasn't exactly sure what to look for.
So basically put, I think these .dat files are just compressed .bin files, and said .bin files can be played in a Genesis emulator... but I've no idea how to get into the .dat files (extract them?) so I can replace that file with something else (or at least, create a whole new .dat file and just exchange the two), so I'm kinda stuck. I figured I'd try to get some help here, if any of you folks know what to do here.
Anyone have any suggestions?
And, because it'll surely be asked, this is the whole (yet silly) point of why I'm actually trying to do this; I want to replace one of the roms with Rocket Knight Adventures. Yeah, I know, there's no guarantee it'll work if I even somehow find a way to insert it, and I know I can just play the game on a PC or Wii Homebrew emulator... but I love the Wii U Pro Controller, and I don't think the guy who's making GenPlus GX is going to add support for it anytime soon (since he labeled it as "Low Priority"). So, yeah.... the whole ridiculous point of this is to play one game with the Wii U Pro controller, because I want to use that instead of a Wiimote.
(It's one of my favorite games of all times, if that helps excuse why I'm trying something so ridiculous. Also, apparently Rocket Knight Adventures and Sonic the Hedgehog 2 are exactly the same size, so I figured exchanging the two wouldn't actually be too difficult... once i figure out this whole .dat hurdle.)
