This is more of a suggestion. But also an issue. The 3.0 Beta2 doesn't have the last TWL_FIRM patch that allows NULL sigs. As a result I'm getting a lot of users complaining about the "Error has occurred" problem when they try various custom DSiWare SRLs. I keep having to tell them to not use 3.0 Beta2 and find a nightly build that is newer.
I suggest you either pull the build or at least add a beta3 of that build with the updated TWL elf file. It's causing confusion and I would like to see it rectified.
