Right mobs for Any version Really:
Mon20 is referenced by Appr 190-199. Although the clients can access and read MON21 and maybe even 22 - the server (3.38 at least) does not know what to do with these mobs and you end of with a NPC / Invisible along with a Shadow for some reason.
What we do to access Mon21 is rename it to DMon-1 - this has been here since MIr3 2.9 through to Job and now 3G. To make these appear on screen, you use the Appr's of:
2000 - First mob in DMon-1
2010 - Second mob in DMon-1
and so forth until...
2090 - Last mob In DMon-1
So now we have all the mons from 1 - 21 in the game withot any Wil Editing but what about Mon22 though?? Well the only Way I found to add them was by Injecting them into the other MON files ---but--- you have to be carefull which ones or they flash and all sorts...
As regards 17NG, he used to chat to me a lot, even though I struggled with Chinese and he struggled with English. I noticed he stopped been online/chatting as SOON as I started talking about 3.55 - I also cannot access his site for some time now. I bet he even thinks I shared the programs he passed to me (which I have not) even though some of them started to appear on various Chinese Sites...He also has not been online on QQ Either for a while.
If we take 3.3X as a good example though, not only did I figure out Why there was problems for Non-Chinese O/S but also worked out how to add a lot of things in, not having 3.5X means I cannot aid yourself for example in trying to get various new stuff working and if it needs some mad front end before it all works, then tbh Im glad I never paid for a copy.
Now another question - you paid 17NG some hard cash - you would half expect to get the newer versions from him/his site such as 3.58 etc which has 17 New Magics in there for example (think thats the number)...Personally Ill just wait till its cracked myself - Mir3 is def not worth any money period in my eyes..
