Uses for memory card MCID, Kbit, Kc?
I've been using MCID_PAL.ELF to get the MCID/Kbit/Kc info for my memory cards. Question is, what is that info useful for?
Would it (in theory) be possible to write a program which uses that ID info to sign ELF files for that specific memory card? Then you could e.g. install Free McBoot using a non-Sony PS2 memory card USB adaptor. (Get an image of the card, and run MCID_PAL.ELF on a PS2 to get the ID info. The program would then use that info to sign the FMCB ELF file. You could then copy the signed file into the memory card image and write it back to the card.)
Or maybe in future (when PS2 emulators get better) you could properly emulate a memory card with Free McBoot or similar installed.
Is there any other software which can use memory card ID info? (Maybe a modified version of ps3mca-tool could be made to work with non-Sony USB adaptors? The user would pass Kbit/Kc etc on the command line instead of reading it from the USB adaptor.)
