But can he 'add new stuff'?
I think there is gross misunderstanding here, if I get what OP talks about. I am afraid by crap he means that all files, besides technical difficulties making them run, are unconfigured and that means C# files also even with daneo1989 database.
Yes it has a lot of stuff configured, I don't want to slight that, but all the same tons and tons of it is unconfigured bare bones and unplayable (of which only easy fix is putting in korean exp table, all else like various npcs for those specialties like awakening, fishing, crafting, refining, including those common, legendary, mystic items... (I suppose those along with awakening and fishing are not considered 'euro') you have to script (I am probably wrong on some count, just saying it how I see it).
I realize that for the 'clique' of you experts around here its a cinch but for 99% of pple around mir universe it is unsurmountable obstacle to run mir server on home pc for themselves, like for family or few close friends. I believe I could swing it myself but would have to put in considerable time and learn quite a bit while doing it. I doubt most 'normal' folks could do that even given time and will to have a go at it.
I went over C# files recently because having free time, being flushed out of mir server, being in between 'jobs' playing mir, and I must say the more I look at the files the more I have respect for those able to knock together half decent server. On the other hand, most servers are not too integrated, balanced either, as many if not most settings in the basic files are typically left at their defaults (pot costs, basic mount costs and many such likes). Tuning it up would require the server maker to actually play the server as rank and file char prior to putting the server online for public and I doubt any of those who put up servers do that. And 'beta' runs can't do that. I quite admire the original euro balance that everybody making server today is still using as a starting balance point one way or another.
"he has a crapy gfx card so he gets a black screen" -> C# can be run in a window and then it almost always works, unfortunately default is full screen which most pcs have problem with although old pc shouldn't have, probably you have missing directx or dot.net framework stuff or things of that kind, unless you mean black maps ingame, then you are missing database LOL
Anyway making files to run other than C# ones is $% rocket science, complex setup, at least that's how I recall it when I looked at it years ago, its nothing to mess about with for us 'normal' pple LOL
Crystal files by comparison to all other files are user friendly, even extremely friendly unless you are not computer literate, but not quite ready to play as they come off the shelf and I mean play in the most basic way, that is resembling euro with its features and npcs and all that. Don't know exactly up to what point the items, mobs, drop files are configured, it it covers all standard euro caves.
I doubt any of the 'bigger servers' would be for sale (or doubt somebody would be willing to put up the amount large enough to 'persuade' those with extensively configured server files) but perhaps some of those 'smaller ones' that were online for relatively short time and then ended, the one-man affairs, like Purgatory (ran like a year or two earlier?) or now the Emerge server? In any case it is clear nobody is willing to throw in 'free for all' at least part of his work, like Far and likely others around the files development did or daneo1989 with his database.
