Commando
- simple hit registeing seems to work, need to check gun code (readme.doc bottom + c.s gun)
- newcon reset after reset is depressed
OK!
- first non-lag frame after starting the game and pressing reset:
OK! .loop1 .dosw
- top most 1px line? I couldn't see it on a playthrough video like this one

edit: the videos I see are cropped from top
edit2 Alien Brigade
- light gun X coordinate seems to be fishy. You can't really hit enemies on the very left side and moving through the right side, there are columns that skipped if you are moving on the same row (with minimal Y pos differences).
- if you wait for the first enemy to appear in front of you (3rd enemy probably), you can hit him farther on the right side but not enough close on the left side.
- same enemy, but for Y pos, you can't hit him above the fortress wall/bar but able to kill him above his head. Try shooting under the
menu bar and you will see the big distance between cursor and shot particles.
- I can't test it with controller (with cursor). Controllers joystick: can't shoot. I also had a random glitch from changing light gun to joystick, reset core, start game, white screen every 3rd-4th frame (like an autofire) without any input pressed/shown in display
edit3: Barnyard Blaster - very good to test shooting after title screen. Shoot once to pick mode. Shoot 8 times on the screen and it goes back to title screen.
- offscreen left side: left side always register hits
- ofscreen right side: depends on X position, sometimes register sometimes not
- offscreen top side: Y pos 5, hit will register at X pos 1, Y pos ~16
- offscreen bottom: 226 y pos, there will be 1 registered shot, seems to be totally random when does it gets registered on screen.
Another milestone is finally reached wiith Scrapyard Dog's sewer level finally being correctly emulated. This level was another main driver for me to create this emulator after seeing Mothrayas' TAS of this game contain a pretty bad graphical glitch in this level.
What this glitch comes down to is DMA timing around what is called 'holey DMA.' Basically DMA can be told to ignore certain address blocks, and when it does so there is no DMA read penalty for addresses in that block.
Except, there is a penalty for the first read in order to identify that block in the first place. Getting this (and pretty much everything else DMA related) right is what fixes scrapyard dog.
EDIT: @MESHUGGAH: I unified the controller definitions between EMU7800 and A7800Hawk (at least for 2 button and joystick controllers) so you should be able to compare movies now I think.
