Just to repack your indices you can use the repack method found in 90% of clients. Go to client.java and search for "repackCache". 1 is models, 2 is animations, 3 is sounds, 4 is maps, 5 is textures (occasionally). Uncomment the line that should be there and the next time you run your client, then the new data will be packed. You also need the loc.dat/idx, the map_index, the npc, obj, varbit, and item definition files and anything i'm inevitably forgetting. You'll also need the read values since i'd imagine yours are not current
