The ME, the unknown being?

[propbeanie]

Specific references are made with each release of FotRSU: "This version is NOT compatible with previous releases. You must empty your Save folder and install on a fresh copy of FotRSU."

That said, it is relatively easy to make edits to missions from previous versions. All of the changes are documented in s7rikeback's excellent XLS spreadsheets of the available assets in the game, along with their Type= numbers and Class= names. The Type= is the biggie usually, though we have changed Classes of ships more than once through the life of the mod. Look in the Support folder of the old v0.80 for "Equipment & Unit list for FotrsU.xlsx", and it will get you most of the way there. You can sometimes use the Mission Editor's error messages that pop-up as your mission loads, but you won't always get an error message except maybe 10% of the time. The only ways you know a mission doesn't work is by opening it in the editor and trying to zoom-in, or move around the globe. If the screen goes white, or the Editor bombs in other inappropriate manners (there are many), then you know the mission does not match the mod. The other way to find out is to play the mission. Either you'll CTD, or things will be very different from what you intended...

What you need to do, is open your MIS file in a good text editor. MS Notepad works, but can be fidgety, wanting to rename your files with a dot txt extension (use the "Save as... All Types" drop-down in the Save dialog under your file name) - Notepad++ is an excellent freeware choice, and the 010 Editor is even better, especially for complex "Search and Replace" tasks, but it does cost $50 US to purchase the application. Well worth the investment if you do much programming / editing / scripting. Once you're in the text editor of your choice, you'll want to "Find" or "Search" on a particular ship class, and double-check its Type= line, and make certain that they match what the game calls for. This may well take a while. I have to do this every time we've made edits to the mod, and it can be quite time-consuming. I do have scripts that I can run to help, but a lot of the issue is still human-eye-to-brain recognition.

Open the Data / Roster folder, and the Names.cfg file. You'll see listings toward the top of the file of the ClassNames used. Below those sections are the Sections for the naming of the Air, Land, Sea and Submarine individual Classes. In your MIS file, you'll want to match what you used these to the different assets in Names.cfg, Equipment & Unit list for FotrsU.xlsx, and you might have to access the different nations Roster folders and the Air, Sea, Land or Sub folders of each asset used.

Things to look for in FotRSU:

1. Battleships - BB can be Type=11 or Type=19. The Type=19 is the majority of this Class, and they carry Scout Planes (Stock game's "Type19=Super Fleet carrier" renamed to "Heavy Warship with Scout Planes"). There are generally speaking 2 BB of each nation (that has BB) that will be Type=11, so that an un-edited GENERIC call will still bring in a ship.
2. Heavy Cruisers - CA can by either Type=7 or Type=19. Notice that the CA can be in the same Class as the BB? You do have to be careful with a GENERIC Type=19 call, since you might not get a BB or CA as you wanted, but rather either or.
3. Light Cruisers - CL can be either Type=6 or Type=18. Again, the Type=18 designation has been renamed from Stock's "Type18=Elite Escort Carrier" to "Light Warship with Scout Planes".
4. Submarines - SS, yes, submarines... The AI subs can also be Type=18, "Light Warship with Scout Planes". There are at least four Japanese submarine classes that carry and launch planes from a catapult (OK, so they "Spawn" in). You will encounter them in-game at times. If you are ever out in the middle of nowhere, and you see a small floatplane, it probably came from an IJN submarine.
5. Submarines (again) SS - again with the submarines. All of the other AI submarines are Type=17, which in the Stock game is "Elite Destroyer Escort", renamed in the FotRSU mod to "Type17=Submarine". They are surface-only vessels. Do NOT use any Type=200 subs in any of your missions, except for ones that are player-controlled. If you don't adhere to this, the gauges on the players' subs will stick to a 12 O'Clock high position, and do not move. You have been warned.
6. Some small coastal vessels that have engines in them have been re-designated as "Type=108", which in the Names.cfg of Stock is "Type108=Rare Cargo ship", but in FotRSU is now "Type108=Motorized Coastal Vessel". This was done so that all vessels that make a definite noise can be heard on the Sonar Station by both the player and the AI. "Other coastal vessels, such as junks and Sampans are still Type=104, but their Names.cfg designation has changed to "Type104=Non Motorized Coastal Vessel" from the Stock's "Type104=Coastal Vessel".
7. Type=109 is a special case, in that it was reserved in Stock and a lot of mods, including FotRSU originally. The Conte Verde (European Liner)
   was often the only vessel in that Type designation. Since it wasn't very "rare" in the game anyway, we moved it to the Type=103 set for "Troop Ship", and call that Type specifically. The Type=109 is now the Photo Target for the PhotoOp SpecOps, which are in the process of being rebuilt. We did several iterations of a PhotoOp target, but could not get the RecManual to cooperate with us, unless it was designated a "Ship", so it is Type=109.

The ships with the Type= changes will adhere to their original Stock game's AI settings, which means that a BB or CA or CL or IJN sub will launch float planes almost immediately upon detecting your submarine. Those classes are old "Elite" vessels. Therefore, the "Elite Black Swan" and others like it cannot be used in FotRSU. Just make the crew "Elite". The AI subs now are also "elite", and will not only attack, but chase the players' subs. Also, be aware, since I don't think we've gotten this info out yet, that some of the top speeds of various ships have been changed. So if after you get a mis file to open properly in the ME, but you can't edit the waypoints etc., check the Group or Unit's "Properties", and see what the speed is set to. I'm still going through the mod again for more of those kinds of issues. This is where searching the text with the 010 Editor's Search with a script really shines, since I can "qualify" each search to a specific class of ship, and only find "hits" for that particular Class that exceeds its top speed. When I find one, I can then change all of the ships in a particular group that sail with it, that must also be "speed restricted", since the slowest vessel dictates a group's max speed...

Now, I may well have forgotten something... if I did, just yell, and I'll try and correct any omissions or mistakes.
