Hello
Let me just say that I love what you are doing.
I was checking out your PSX LibCrypt protection guide and I noticed the link for the PSX Copy Protection list (bottom of page) is down. It seems the author has moved it here: http://www.reocities.com/timessquare/dragon/3926/
I'm not sure if it matters though because your list can be found here: http://redump.org/discs/system/psx/libcrypt/2/
Maybe update the link with either the reocities site, or your page
Also in the guide, PSXDB (site is down I think) is referred as a place to dl .spi files. You can get all your .spi files here correct?
One more thing. 
Should the sbi2sub app be added to the Tools of the Trade thread?
Fixing and adding those would make it a whole lot easier for someone like me to find sbi2sub and the .spi files.
