  - (fixed) player walks on spot on stage clear;
  - several enemies seems to not like a missing min/max range limit for a specific operation?

  heated barrel
  - gives random value to hi-score if you continue (only the first time, not a bug?);
  - (fixed?) throws random address exceptions at level 3 and above, a RAM address arrives corrupt in the snippet at 0x136a;
  - (fixed?) some corrupt sprites, probably a non-fatal version of the one above;
  - stage 2 boss attacks only in vertical (regressed with the 130e / 3b30 / 42c2 command merge);

+ - stage 3 mid-boss still has the sprite garbage bug;
+ - stage 4: has sprite stuck on bottom-left of screen;
+ - palette dims too much on attract / continue screen. 
+   It's known that the DMA data arrangement gives same results on a real Legionnaire board, so shrug
