Comverts ISO (PS2 & DC rips rips), BIN+CUE (PS1 & blue PS2 rips) and GDI (Dreamcast rips) to compressed CHD format, and back.
PCSX2 (PS2--see entry 1665) and Flycast (DC--see entry 1615) can load CHD files. Since those emulators can't read the game data from zip or 7z-compressed files, this saves you HD space!
For instance, it took the three DC games CvSP, SSF2X, and KOF2000 from 2.89 GB combined to just 1.38 GB--and each one ends up as just one file, whereas before they were a bunch of files each in separate folders. That's not QUITE as good as 7z (1.31 GB; and no, 7zing the CHDs doesn't compress them further 'p')--but zipped ROMs aren't readable by those emulators. |

(Note: when running the .bat on DC rips, it makes separate .chd files for all of their .gdi and .iso files--but also combines everything into a big .chd file; the smaller component .chd files aren't needed after that.) |
