Beliveve me or not, but i think not the right place to expose code of the game....
But, belting is AP /HET (with explosion radius of 4 cm, instead 15 for the US m.2 with similar power) and APT
No API, no APIT.... era pictures show clearly API and APIT in belt with a more probable belting with API/APIT/HET.... (what i have done).
So, clealy undermodeled..... they are now more efficients, but less than M2 or Berezin.
BTW, for IAR 81a, we have standardard 303 and MG131, for A6M5 MG-FF and MG131, US M2 at 900 rpm for KI43-II and so on....
DOn't speak about HO103, Hispano and so on
