It IS a way around the copy protection, the LBA 45000 trick places the game data to ####tt at an LBA of 45000 on the disc, this is how an original GD-ROM is set up.

If you think about it when you back up a game, you exactly copy the game data to your pc, but when you burn it it doesen't work sometimes right, this is because the copy protection has to be defeated and the LBA info has to be corrected, but the files are exact copies of the GD-ROM so why does'nt it work?
It is because that when we burn games the LBA structure of the game data changes from 45000 (ORIGINAL GD-ROM) to whatever you type in when "binhacking" (after burning the AUDIO.RAW) 11700 or 11702 but the DC is looking for info at LBA 45000 until the 1st_read.bin is hacked. The 1st_read.bin has to tell the DC were the LBA game data is ####ting at.

So if you copy a game using the 45000 trick the DC sees it as an original GD-ROM and should boot ok. The problem with the 45000 trick is that it takes up roughly 80MB of valuable disc space when trying to copy large games such as SONIC.

Hope this helps
