Files on FileTrip has been migrated on GBAtemp download section. Unfortunately, the revisions did not and it only included the latest file, this affected the boxart files, but I do have a backup from 2013. Hopefully some of the older stuff uploaded on FileTrip has been mirrored elsewhere.
I'm not sure I'd want to update the 500+ roms to the db, mainly as I don't know which scene numbering I should be following at this point. I believe I continued following DS-Scene as Rascal or someone else was using, but it is now behind advanscene. I also don't know which numbering was used before. I feel like a new db should be converted from advancescene's xml db, but advancescene boxart is watermarked. I'm also not sure if we really need this rom manager tool or need it to be accurate, isn't there a better tool by now? High capacity memory card is also cheap, you could probably have almost all trimmed games on one now as well so not sure about the absolute need for a tool like this.
Anyway here are some links below. If you are using zip ROM and want some icons download icons 4621 file and copy over IconCache.rod over. Download my 6220 from dropbox and copy over the images and ds.rod database. Images in this archive have been compressed a bit more than before. The old 6174 links are only posted here for completion. Will probably upload the 6220 files to them at some point.
