Where are they saved in? I ran the games, but no encrypted or decrypted files are found...There is a solution.
1.Run the game in mame
3.Rename encrypted file in the root directory to ikaruga.bin
5.Zip ikaruga.bin and place it into roms folder of Demul
Arcade games have nothing to do with gdrCHD plugin.
Can you please attach your mame and explain detailed the process?
