i can't speak for GoodNES, but i assume it's based on Roman's GoodNES set

as for GoodPCE and GoodSAMC the datfiles are good tools based, but with the addition of file sizes (good tools internal database only has 'name vs crc32' data)

i think that GoodPCE and GoodSAMC should not be flaged with
* - CRC32s are calculated WITH possible changing header information (but checked with Good****.exe)
cause in fact all files in those 2 datfiles are both headerless and non-interleaved
and unlike NES, emulators for PCE and SAMC don't require files to be headered
