Tools Used:Wii Backup Manager (after adding your game, go to 'Transfer' and select 'WBFS') or wit (Wiimms ISO Tools).Gain: Immediate (ISO dump size lowers).Archive-quality dump? Not directly, see note about reversing.Games relying on direct sector access (as opposed to consulting the filesystem) will break if you trim them. The trimmed file can be used immediately at a smaller size without compression, but the game's internal structure will be wholly modified. Trimming (also known as 'trucha scrubbing', and substantially different from the definition of 'trimming' used in ROM-based systems) games will also defragment the files moving them towards the start of the disc image, resulting in a smaller ISO file. PlayStation 3's ps1_netemu can also use it after packaging it into a PS1 Classic and installing said package. Playable on Emulators? RetroArch, PCSX-R, and ePSXe.Playable on Hardware? On PSP, not on PS1.There's data loss, but it's negligible in terms of functionality. For commercial releases from PSN you will have to use PSXtract. For homemade EBOOTs it can be done by using the same tool to generate the BIN+CUE files. Tools Used:PSX2PSP, Popstation MD GUI, CDDA-ENABLER (optimized for PS3).Gain: Immediate (ISO size decreases a lot).
Playable on Emulators? Only on recent SVN builds of PCSX-R and ePSXe (they also support 7zip/gzip/zip archives so use them with ECM).Check the hash with Redump to make sure nothing was altered. Can be reverted? Yes, using the same tools (unECM), however there is data loss (error correction data) which can damage a select few games.Drag-and-drop the ISO onto the specified tool, then compress it with 7zip.

ECM only zeroes out redundant error correction data, but in some rare cases this data may be used for anti-piracy, hence corrupting the dump! However it does achieves drastic size reductions when compressed to an archive format (7zip/gzip/zip).
