The guide is very old do not try to find and or use the tools from the guide there are much newer tools available even tools that allow you to skip resourcing files into the resource folder and instead allow you to write them directly into the data files...
That being said both the ncarbon dumper which I still use and the advanced client dumper are still 2 valid tools to get resource files out of other clients but rMod and Grimoire can also perform resource extraction from data files.
Glandu2 has a nice RDB tool that work well in the original resource folder type rdb creation and importing rdbs into the database.
Some of the data direct tools include releases like rMod and Grimoire from SilentWisdom and you can find links to most of the client tools in the collection thread...
Listed under client tools.
I don't believe there are any videos.
For your item LamiaCores guide on the 9.4 item resource and item ref may also help if you are working with 9.4 files...
Both Glandu2's rdb tool and rMod support working with the new item structure.
