I liked this manager when it was first released. It was the first to incorporate the hermes payload and allowed for the playback of split games from external. Now it also allows the playback of PS1 .img files as well. I can't wait until open cobra is put out for everyone to see and gets incorporated into this BM.
MultiMAN has just become too heavy over these last few years. Now if we ever see plugins like what we had on the PSP and we could set MultiMAN to autoboot instead of the XMB (like IRShell on PSP) then multiMAN would be my favorite, but in the current form I have actually stayed away from it. I have used Rogero and Iris manager for a very long time now. A BM should be a BM and not a million other things as well. Don't take this as me bashing MM, but I just prefer the simplicity of other BMs.
