A few utilities to help with management of PlayStation2 Memory Cards.
The main part is the mymc utility, which does brunt of the PS2 Memory Card management1.
However, SD2PSX doesn't readily work with it.
The reason is that SD2PSX uses raw 512 byte sectors, whereas mymc uses 528 byte sectors (data + 12B checksum + 4B padding).
To that end I wrote two small utils (sectorpad.rb and sectorstrip.rb) that allow you to Hobbit the format2.
Say that you got yourself shiny new Card1-1.mcd thanks to SD2PSX3.
$ ruby sectorpad.rb Card1-1.mcd Card1-1.ps2
+ Input size OK (RAW 8MB card with 512B sectors)
+ Done.
$ python2 mymc/mymc.py Card1-1.ps2 ls

# other mymc commands here (adding / extracting files, etc)
$ ruby sectorstrip.rb Card1-1.ps2 Card1-1.mcd
+ This is padded 8MB card, cool.
+ Done.$ python2 mymc.py blank.ps2 format
# rest of commands (if you wish)
$ ruby sectorstrip.rb blank.ps2 blank.mcd
+ This is padded 8MB card, cool.
+ Done.Please note: signed/encrypted elf files are specific to the one card. It won't be possible to shuffle them to a different card. That said, looks like sd2psx uses the same ID for all cards. :-)
Also note: extracting and repackaging will break file linking, resulting in more space wasted. You might not care, though. Especially if you use this for sd2psx.
