Note: COSI size is based on total size of both files.

The next tests are done on actual psx cd images, which will probably be the main use of this program.
Type | Size |
Original Size: | 249,681,264 bytes |
ECM Compression: | 221,169,453 bytes |
COSI Compression: | 219,364,757 bytes |

Original Size: | 284,624,928 bytes |
ECM Compression: | 266,696,032 bytes |
COSI Compression: | 235,666,470 bytes |
As you can see, COSI's compression will always be better than ECM's (sometimes slightly and other times dramatically depending on the image).
Note: All the images tested on were able to be decompressed and matched the originals 100%.
