well i decided to try a interresting experiment today my gamecube for some strange reason stoped reading disks not a big deal considering i have two gamecubes so this didn't bother me but i was curious about how the security works on the gamecube so i decided to disassemble my gamecube and figure out why the cd drive stoped working i found that the switch that activaited the cd drive died so instead of fixing it i decided to wire a toggle switch to it to turn the cd drive on and off really easy mod considering the switch has a plug on it that the two wires disconnect from so i wired and installed a toggle switch really easy took about 20 minutes total to do. now the question is why would you want to do this well i idi it to fix my broken gamecube and try a disk swaping technique with it to test security here is the amazing findings i have foun security: the gamecube security is amazingly tight once the game cube reads the header off of the disk it goes to a blank screen then loads the game this is where i tried my experiment at once it went to a blank screnn i fliped the switch which gave me a system cannot read disk error please close system lid so i replaced the cd with another gamecube title when i tried to boot the title i got please insert the original game cd resident evil in the cd drive what does this prove we all know that the sucrity is damn near impossible to bypass on the gamecube true but this answered a interresting question about how a gamecube cd loads while watching the drive spin and read a disk i noticed one thing the cd reads the boot information from the inner track and then loads the game from the 6 track on the cd not the 12 track like everyone thinks then starts the game and starts gameplay after trying this disk swapping i found out this once a gamecube disk loads it loads a speciffic boot file for each game into memory so if you tryed to boot another disk using a swap technique it ownt boot and will ask for the original disk so swap magic or swapping for the gamecube is no way in hell going to work so this are my findings and i hope you find them use full
The security ain't tight once you solder a mod chip to it lol. Ive tride swap tricks before mod chips were out, and you wright they don't work but they do with Freeloader. This is somthing i never understod, do you think the Freeloader shuts down the CD tray untill it picks up a game?.
no what freeloader and action replay do is they load a boot header into memory and that boot header stays in memory and boots any imports or games from other countrys that is why they give you the instructions for boot ing the import from the main system memory see how the action replay works is you start the console up with the door open once it goes into the menu you select game disk then when it says insert a gamecube cd you shut the drive once the action replay icon appears you open the drive door and remove the action replay then place the import cd in the drive and it will boot this is due to the universal header system that action replay has designed for the gamecube and for freeloader that is why freeloader works because datel's crack team found a universal boot header that works on all games
So it could be possible to use this header to not just play imports but backups as well? If you remade freeloader to do that, as you could use the memory to insert the code needed to play backup games, a bit like the sirial expansion mod that came out for PS1. Maybe a swap trick could be possible, but i doubt it will happen, because I think the Gamecube expetecs regular security keys, backups won't have these and I dnt think the information would stay in the Gamecubes memory or dose it? (thinks Of PSO load) One side of me thinks its poss the otherside thinks not. What do you think?
Action Replays and Max Drive Pros with GCoS or Ninjamod could be considered swap tricks since those require you to boot a custom BIOS from the memory card.
no the header cannot be used to boot backups as we can not write backups backwards which is what all the gamecube disks are writin in
