Since Spider3DSTools have been recently released by yifan_lu I believe this html will be handy while debugging.
It eliminates the need of frame.html and browserify convertion. Just place LoadROP.dat with index.html on the server. LoadROP.dat must be 768 long or less (it will be padded with zeroes in JavaScript to run the exploit).




It is possible to specify ROP file name with HTTP GET parameter, like
http://dukesrg.no-ip.org/3ds/rop?MemoryDump.dat
It is also possible to patch filename or binary data inside ROP data
http://dukesrg.no-ip.org/3ds/rop?MemoryDump.dat&memdump.bin
in this case dmc:/memody.bin will be changed to dmc:/memdump.bin
The patching parameter may be one one of the following:
1. HEX (string with only 0-9,a-f,A-F characters used) - patch data bytes at offset 0x220 with this data
2. string (not HEX) - patch first filename found by "dmc:/" prefix (original string in ROP must be aligned to 2 bytes to be found)
3. HEX=HEX same as 1. but offset is specified before "="
4. HEX=string - patch string data bytes at offset specified before "=" character (offset will be alignet to 2 bytes)
ROP files available at the server:
All those ROP chains proved to work on firmware 9.0-9.4 (the latest for the moment) if version is not noticed, but several may partly or fully working on 3DS browser version 1.7567 (i.e. firmware 7.1 and above). Can be easily launched on 3DS from 3DS Online Tools.
