Ok so I am running Fission now and am eager to get to a more current ROM. As I understand it, GRD is a conversion tool to port D2 roms to D2G right? If this is the case will I just be able to download a ported version of Fission or whatever release i want? or will I need to use GRD myself to install them?
Here is what I understand about D2G ROM's- at the moment, Fission 2.4.3 is the newest, most stable ROM available for us. Older versions work, and that is all that is available (stable).
GRD has used various versions of the ROMmers with other ROM's. Some work, some don't, none are completely stable.
GRD's newly created ROM appears to be stable in their testing, but there seem to be problems with downloads right now. They are working to get everything repaired (links, not the ROM) ASAP.
So here it is in a nutshell- if you want new & stable, Fission 2.4.3. If you don't mind dealing with a few issues, read through the GRD ROM'mer tools section and try some of those. If you want to wait for the newest (and probably the coolest!) but not quite yet available, it is GRD's new ROM.
Personally, I'm using 2.4.3 but waiting for the links to the new GRD. With home launchers, themes, and wallpapers, you can make a ROM your own, so to speak.
Good luck with it!
