I tried running your script, but it gave on error on this line:gui.drawbox(187+x*4+pl*28, 215+y*4, 189+x*4+pl*28, 217+y*4, color)

endThere are, in fact, no bitwise operators. Lua itself doesn't even have AND, OR, etc. DeHackEd added those to Snes9x himself, and it wouldn't be difficult to add shift functions.
You can use semicolons to put multiple statements on one line... possibly with some caveats.
If you've found where the game stores hitbox coordinates, a call to gui.drawbox() is all you need, IIRC.

endWell, I overwrote the entire 0x6000 0x61E9 region with zeroes, and couldn't hit the terrain anywhere in the level, including the brain at the end. Setting it to 1 would logically make every 4th tile deadly, and sure enough, I can keep the ship in a tiny invisible column of safety before being crushed against the side of the screen. Your findings seem to be correct.
0x0043 - Stage sub-position
0x0044 - Stage position
0x0045 - Stage position * 256
0x0041 - 0 = side view 1 = top-down view ... I think...
0x035C - 1P X-pos 0x0064 - 1P subX
0x0337 - 1P Y-pos 0x0062 - 1P subY
0x035D - 2P X-pos 0x0065 - 2P subX
0x0338 - 2P Y-pos 0x0063 - 2P subY
0x0070 - 1P speed Each speed up is +1/4 pixel/frame
0x0071 - 2P speed At 0 speed, movement at 5/4 px/fr...Waitaminute, didn't the windows build of FCEUX already have this feature?
Can't say I've succeeded at discovering tile or collision data in RAM before, though it would be indispensable for some bots I've been meaning to write. I've already got my own set of memory search functions, so I may conjure up a custom function to detect the memory structure(s) we're interested in. That should be interesting, if not altogether useful.
the game is actualy shorter than the ending, it would be silly to refuse a 1 min movie that actualy complete a game...

endThere's also one around at least the top hand (dunno if there's one near the bottom hand too) just before entering the blue section of level 1.
Thanks FatRatKing for your PM. Your advice was extremely useful.
Also, FatRatKnight, I want to apologize for volunteering your assistance without your knowledge, or permission. That was a bit thoughtless on my part. :/
