vmu read and write

[kof888]

Thank you for your help. At present, the file reading function of the katana game has been found. After reading a few games, it seems to be similar. It seems to be the function library of katana.

The current result is that the game archive can be encrypted, decrypted or compressed (many games have a separate set in addition to the CRC set with the system, and some games have too large archives, such as Advanced Daisenryaku 2001, which actually requires 194 frames. The memory card space, if we simply compress it, theoretically it can be reduced by half)

But if I want to copy the archive reading function and use it alone, it's too difficult. Give up temporarily...
