(codebreaker can also be used)
When you get this working and use CSL(Cog Swap Loader) use this procedure to boot backed up ps2 games...
1. boot with exploited memory card and trigger disk
2. select CSL from menu, (may have to navigate a bit)
3. hit the open button and insert an original ps2 game
4. let the game load(just listen until the disk stops making noise/stops)
5. Press x and let the game spin, upon finishing a USE COG SWAP will appear
6. Use your loading device(fliptop/slidecard) and insert backed up media
7. Press x to load the game
This exploit works with all version 1-10 systems. It is in fact for playing backup games primarily, but also has other executable files you can use(google .ELF files). Sony realized the exploit and fixed the Ps2 slimlines, therefore only version 1-10 systems will work.
