IDA pro and Hex-Rays decompiler version question

[jonwil]

Anyone know of a fix for 6.5 to remove the "sorry, that idb is created by pirate IDA" error? (of course if I cant find a fix, I could always use IDA 6.5 to reverse engineer itself, find the "pirate check" code myself and make a fix
Also, I have the following plugins:
hexrays_helper.plw
IDA_ClassInformer_Plugin.plw
IDA_ExtraPass_Plugin.plw

Anyone know who wrote them and where I can find versions that will work with 6.5? (or if source code for them is available, that would help too)
Also, an IDA 6.5 SDK (if one exists) would be great (i.e. everything I need to be able to compile an IDA/HexRays plugin and have it work with HexRays x86 1.5.110408 and IDA 6.5.14011)
Tools too (e.g. tilib for making .til files)

HexRays for ARM is nice to have and it works too in my limited testing which is great
