Ok finally finished going through the game and matching up the events with the trainer table and items. Figured the information might be helpful for you to use with the wiki so I copied my lookup tables to google docs.
https://docs.google.com/spreadsheets/d/1mwOh22k1ropW0nDX7BTZfrCUpWiXvw--IwkGl8VDDcs/edit?usp=sharingSome notes about the stuff
About the maps themselves. Events 0-49 are typically standard events such as story missions. 50+ tend to be Items. 2xx are NPCs that only talk to you and 512+ are trainers and after all trainers on the map are numbered it goes on to the named trainers. Then events in the 8xx-9xx range tend to be warps of some kind.
MapDB - Just a reference with the links to the images I uploaded earlier. The names are just to be able to separate the maps as they often have the same name in the game files.
EncounterDB - Encounters mid level and encounter rate in each map. There might be a few places I missed cause honestly I was lazy when I threw the info together.
BattleDB - Matches the Unnamed trainers on each map with their event number to the trainer number in the trainer table.
TrainerDB - Completed trainer table with all relevant information.
EvBattleDB - This is a table I made for all of the special/event battles or more precisely the "Named" trainers. Many of the events to trigger the battles can be hard to identify so this just ties all the event battles to the map where they occur.
ItemLocDB - Ties map number and event number to the item that you get.
ConnectionDB - Simply shows which maps and connected to others through warps. The one exception is with map 19 that ties to Makai, the map doesn't show a warp but it does act as a warp so I included it anyways.
Some more about the Trainer and Battle tables. All of the trainers are accounted for in the game other then the following.
0 Seems to be a test battle nothing special... Potentially called on for the starter encounter but that is likely calling a wild encounter based on how the AI acts.
12-16 Not in the game at all but perhaps these were used in the demo?
500 maybe a placeholder? the real stuff starts at 512
587-592 These are the fairies down in the unaccessible area in the scarlet devil mansion. The issue is that there is one more event then there are trainers to assign to them meaning one of them is a double up. I might fill them in later but for now you can't get to it normally anyways so I wont worry about it.
1021-1023 These are all test battles found on the debug maps. You can't access them normally so I didn't bother dealing with them.
Also something I plan to get eventually but did not think of when I did my quick run through of the game was to record all of the shops and what you can get and which maps they are on.
