Whoa whoa. I'm not looking for extremely precise information (though it'll be good for some of our trustworthy members to know/to have the flame passed down to them, even if it is not public). Not having information passed down to the next generation typically leads to lost information, and eventually, the death of a civilization.
Don't even need the exact steps. Let's say if I'm told a NDS flash cart could overwrite a dev cart, that's pretty much enough information to detail how bloody easy it is.
We previously already had an inkling that a certain mass gba reader could act as a rewriter for dev carts. It was previously speculated that these event carts were likely dupes to begin with.
As much as this fear is well founded, given that we already have the information that people are rewriting dev carts to sell as event carts, I think it has already been happening behind our community's back.
After all, people who were able to obtain the writer and the dev carts, likely already had this information at their disposal when they made the purchase, and they had the past 10-15 years to make all the modifications they want, and that's excluding any suspicious/unscrupulous activity.
People with the tools and the devcarts has been doing this for years. If they were going to contribute them as a part of preservation, they had 10-15 years to do it.
They probably already made up their minds a long time ago, regardless whether to hoard or sell as modified duplicate copies, just like how many others made up their minds a long time to ago that private preservation is better than a public preservation.
I'm not arguing which view is better, as I'm sure there's merits to either argument, but I'm just saying that the situation has been dire for this long, just that we weren't aware of it.
I don't see how this information would potentially make things worse, when I imagine unscrupulous actors likely bought up all the dev carts they could find to resell as events, and they had over a decade to do it.
