Finally got around to dropping by again.
The idea I had would function along the lines of selecting a particualr save file to load up. -- it could literally be any save file and not necessarily a clear game save. For example, take Chrono Trigger. You required a clear game save, then loading a New Game+ the save you selected was irrelevant --. After selecting the desired save file, an app could hack in the apropriate values while the player loads up a New Game through FF7PC. Once it is booting they could simply close the app, and save normally.
An external app would likely be the easiest method. There will likely be a whole bunch of issues to contend with, such as who's statistics/level are dependant upon Cloud's, or are pre-defined within the binary itself.
If so, then numorous hacks would need to be made to eliminate and remedy all such instances, for a truely complete NG+ mod. Needless to say, such a situation would be a serious pain in the ass.
Anyway, I suggested the idea, because utilizing Jenova, to transfer every detail item by item between save files is a serious pain in the ass. Is just giving yourself master everything a solution? Nah, it doesn't have the same feel that an NG+ would.
The key here is simply automation. The less trouble end users have to go through, the better the feature.
So let's assume character levels/stats are out of the question. Fair enough. But how about items/materia(+AP)/weapons/accessories? All of this can easily be read from a save file, and either actively hacked back into memory, or simply thrown into another save file. I am infavor of the later, since the player would simply need to select the seed file (which contains the equipment/etc) and the recieving file to be hacked. Click go and then they're ripe to load it as ussual. Yeah, it is a far cry from having all of that fun stuff RIGHT from the begining, but it is the difference of 10 minutes of gameplay, and we could at least pick up all of the goodies for the first boss fight.
Ultimately, a save file editor that is dumbed down but tailor made to swap items from one game to another quick and easily is a great and perfectly realistic goal.
Ah well. Just an idea, and I am rambling too much. If the coders out there are interested, consider this just inspiration. I'd rather the folks with the talents pursue something they are genuinely interested in.
