Reverse Engineered and Modified screenshot plugin for NTR CFW 1.0 and 2.x

Since screenshot plugin source is not available publicly, I use the binary version then deassembly and decompile it. Hopefully open sourcing could bring more 3DS applications with built-in screenshot capabilities (and making the improvement or fixes to the existing problems).

Currently ntr.bin still has a problem for a game like animal crossing when closing NTR CFW menu (i.e. bottom screen replicates the top screen). Without any fix to that problem, in order to be able to get the bottom screenshot, the bottom screen is saved before the top one (notes: it may not work all the time) to quickly copy the data before changing.

Thanks to the following people for providing me with learning opportunity:

• cell9 for NTR CFW and all plugins
• patois for NTR CFW Disasm
• enler for NTR CFW DEX
• smealum for libctru
• Others who helped with testing and suggestions
