NES Flips Wrapper

[Europia79]

@Alcaro heya Alcaro, per our previous discussion, I have been playing around with the flips manifest feature.

And one of the more problematic aspects of patches has to do with the NES, because often times, a Romhacking Author will just create a patch with whatever Parent/Base/Clean ROM that they have on hand, without regard to the availability of that particular ROM (whether it's common or rare): And if the Baserom is extremely rare, then it makes it really difficult to apply the patch.

And often times, the only reason for the differences between these NES roms is simply which Header it has: Whether it's iNes version 1 (signed/unsigned), iNes version 2, etc.

So, I was thinking a good strategy here would be to automatically detect these kinds of headers and create the patch against the headerless Baserom and headerless modified rom with the Hack/Translation Header saved to the .bps manifest ?

Here is a mockup script for that purpose (WIP):

Altho, I am definitely open to alternative strategies that address this problem ?

EDIT: Anyways, I thought this would be a really cool feature for the BPS: Something that no other format could offer ?
Sure, as far as only a few roms are concerned, this is really nothing major: But if you're trying to preserve thousands upon thousands of hacks & translations (like me for example), then I think it's a game changer ?
