does test:
* circulair reference - errors out: "The process cannot access the file '\nor-validationtest\venix.bin' because it is being used by another process." -> result = OK

==== Conclusion ====
Conclusion : '''<span style="white; color:red!important;">USELESS</span>''', brickdumps will still show as 'valid' and corrupt patch files will be generated, not preventing the user from permabricking. <br />

==== Recomendation ====
'''<span style="white; color:red!important;">Recommendation: [[Validating flash dumps|Validate flash dumps]] first and use [http://www.psdevwiki.com/files/flash/Tools/Flowrebuilder/ Flowrebuilder] or [http://www.psdevwiki.com/files/flash/Tools/Progskeet/Winskeet/ Winskeet] with [http://www.psdevwiki.com/files/flash/patches/ autopatcher] instead.'''

==== Note ====
wiki v2 downgrader contains 2 patchsets, used on 3 offsets. Having 9 sounds like a bit of overkill to bloat the binairy.

=== Checks ===
There is not much checked in the patcher:
- only size is checked
- and header "oÿà" (bytereversed, like with progskeet, teensy etc) versus "àÿo" (as E3).

Thus it fails miserably in the comparison of [[Validating_flash_dumps#Flowrebuilder|Flowrebuilder']] options like un/rescramble + de-/interleave, bytereverse, unpacking and autopatching, while checking and informing the user about possible errors in the dump.

==== Conclusion ====
<span style="white; color:red!important;">'''USELESS'''</span>, 100% valid files will be failing 00/ff check. Improper files will be failing 00/ff check too, and no detection of the root of the cause. Nothing was patched and gives the user a permanent false sense of having bad dumps without leads of what to solve.
