Well, it definitely doesn't look good, no

. By the way, you've just reminded me why I sweared I would have
never converted the TP icons to CORE - not that I had forgotten the reasons behind that, heh, but taking a look at those .csv files again brought back this issue to my memory in all of its harshness.
Anyway, let's take it like real men and see what could be done. The thing which I can't really wrap my head around is the lack of some models in the list - yet there actually are icons for them... What does that mean? Does, for example, the US have actual model numbers for jet/rocket interceptors like 13_7, 13_8, 13_9 in its .csv file section, unlike Japan? How does the game treat those?
Apart from the advanced jet models, though, which I can understand not having been listed because of lacking RL counterparts (
although I think they might have put in at least the Nakajima Ki-201 Karyu), the thing which puzzles me the most is that there are even some apparently "basic" models lacking, namely 14_1 and 14_2 (which should be, basing myself on vanilla, Strat. bomber I and II). What gives? I'm not installing CORE just to check this, but could you please tell me how are these two models portrayed in game? Are they in but they lack their name, are they somehow "disabled" for Japan and thus not buildable, are they... hmmm? :unsure:
In summary, what I'd need i.e. I'd ask you to do, is to please prepare me a complete list of Japanese aircraft from bottom to top
as you want/need them to be; basically, this means filling those mysterious (to me) gaps in the .csv file, eventually with not so accurate names, but most importantly by highlighting which model numbers correspond to what types of aircraft. For vanilla that was rather simple - 12_x is fighters, 13_x is interceptors and so on - but I'm afraid for CORE it might not be that simple (I point out again the light/medium bomber distinction which
I know is in somehow, but not exactly under which form).
So, to be clear, you'd have to arrange me something like that (
the aircraft types between ":::" are a guess of mine when it comes especially to 14_x and 15_x):
12_0 [name] :::Fighter:::
12_1 [name] :::Fighter:::
12_2 [name] :::Fighter:::
...
...
13_0 [name] :::Interceptor:::
13_1 [name] :::Interceptor:::
13_2 [name] :::Interceptor:::
...
...
14_0 [name] :::Light bomber:::
14_1 [name] :::Light bomber:::
14_2 [name] :::Heavy bomber:::
14_3 [name] :::Heavy bomber:::
...
15_0 [name] :::Medium bomber:::
15_1 [name] :::Medium bomber:::
...
16_0 [name] :::Naval bomber:::
This way I could concentrate on the actual icons, i.e. on adding to them the proper tags, tier numbers etc. Of course, it would be ideal if you named those which currently aren't since this way I could simply try and "adapt" my already existing icons to their CORE equivalent. If, conversely, you don't do that I'd theorethically have to create new icons basing on CORE names... and there are quite a few of them

(
provided, of course, that I can find them at all: some of them don't seem to be too popular on the web, like e.g. the Mitsubishi Ki-1...).
