It appears that the duplicating hardware that you saw In EDOS Stores such as Electronic Boutique, sped up the ROM blocks. I'm unsure at this time whether custom loaders were also sped up. Instead of 100% loading speed they tend to be 107%. Many of them also seem to have bits that have glued on, but you can strip these away to reveal the correct header and data lengths. The Pilot length always appears to be between 8400~8445. Or maybe it's 8063 ?
