SIDedit.exe    : sid header editor + disassembler, made in perl2exe,
                 unmaintained. I personally don't use it but others find it handy.
siddiag.exe    : diagnostic of header/code errors, memory usage map, trims
                 unused memory at end of sid file                         
sidclean.exe   : newer cleaner also trims at start if needed. still in beta but
                 will replace siddiag and siplay2/hacked                       
sidknown.exe   : identifies duplicates by actually playing the sid and
                 generating md5 hashes from the sid usage             
sidusage.exe   : detailed usage checker, generates a map read by siderror
siderror.exe   : reads maps generated by sidusage and reports badreads/bad
                 execution etc                                            
sldetect.exe   : songleghts.txt generator, actually plays the sids to detect
                 when they loop or stop emitting sounds to determine the    
                 lenghts                                                
sldb_merge.exe : accessory to sldetect.exe, to merge partial outputs
                 eliminating dupes (so sldetect could be run on updates instead
                 of the whole hvsc)                                            
siddump.exe    : hacked to also dump the executed disassembly code mostly used
                 to compare song output of similar/equal songs but also to spot
                 execution errors
