[beta] Trying to run 1.8b map on 1.7.3b, problems

Hi,
At first - for those who may miss this - I'm writing about two years old version of Minecraft from beta era, not the current one

I want to run my old, beta 1.7.3 based server. Sadly, I lost backup of map, got only one after 1.8 (adventure update). Bukkit 1060 is starting with this map fine, some 'new to 1.8' blocks just disappeared (that's OK - almost nobody was playing after this upgrade) BUT there's a problem with items in Chests.
All chests that contain only 'old' (existing in 1.7.3b) items are opening OK, but if it happen there to be 1.8-era item, game client (!) crashes and server throws nullPointerException in ItemStack. If I'll break this chest - the same situation occurs and additionally I cannot enter server anymore (as stack of unknown items is laying on the floor).

Has anybody got an idea how to fix it? Recovery of this map is very important to me. As it seems that the only problem are those items in chests I'm looking for possibility of somehow edit map file directly, removing those elements.

Running beta 1.8 server and removing items would be good - but as this map has just 1GB, I see no way to visit and check every chest

 

kitor Maybe MCEdit can do it, possibly using a custom filter. Removing some/all chests, I mean. I haven't done much with MCEdit though, so maybe someone else will know.

 

I checked how Region (used back then) file format works, and it seems to be easy to just scan all files for occurrence of some item in container, and replace it eg. with cobblestone. As every container items are stored in NBT tree as a few values (count, chest slot ID, damage, item ID) I'm going to write simple tool that will scan map files for me and replace all items that are not in known items array.

I just need to get somehow list of known items for 1.7.3b.

 

I found this -

Thanks, this should help a lot. On minecraftwiki there's one from 1.8b.

 

Why not just run 1.8b and leave the new items alone?

 

Because everything after 1.7.3b is... not cool. I remember many (in case of our server 90%) people stopped playing minecraft when adventure upgrade was introducted. I'm also tired of all those things... void fog, new land generator, sprinting (that killed making rail systems) and so on.
