- (fixed) player walks on spot on stage clear;
- several enemies seems to not like a missing min/max range limit for a specific operation?
(when i.e. first boss goes to bottom of the screen and become unreachable)
- (btanb) Throw is made by quickly double jumping (!)
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);
- (fixed) level 3+ boss movements looks wrong;
- missiles doesn't seem to like our 6200 hookup here;
- stage 3 "homing" missiles doesn't seem to like our 6200 hookup here, except it's NOT 6200!?

- 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
