I have an older version of HBC and the Backup Loader Gamma. I am looking to upgrade to 4.0 and then 4.1, but do I need to remove these two? I am guessing that HBC will overwrite the existing version and I will be fine. However, I have been told that the Backup Loader I am using is not the best...so should I remove it? If so...how? Also, do I need to remove StarFall as I will be loading BootMii and PreLoader?
