Thanks for the video. Sounds like it's a hack of Piranha (which, obviously is a hack of Pac-Man )

DIP switches should be the same as an original Pac-Man. 1 and 2 both ON for freeplay. I think the Falcon PCB's are set up to use 2 different types of audio amps, one on either side of the board, and the volume pot is located next to which ever one they used, so that's why yours might not match the one pictured above (mine looks like the one pictured, except it has the extra ROM board over the ROMS in row 7 and only 2 ROM's in row 5 or 6...they kinda straddle both rows ). As to the difficulty jumper, I'm not sure if these are equipped with them, but it'd surprise me if they aren't. On mine, I see a couple solder jumper pads at 9E, and both lead to the resister bank next to the DIP switch bank. A real Pac-Man PCB's difficulty (and alternate name) jumpers do the same thing. This is just a guess though, and if it messes up your board, don't blame me

Interesting...never saw one of those before. It's a regular Falcon Crazy Kong (FCK-01) PCB converted to run Bagman. They have that in MAME, but it doesn't work. Does it sound any different than a real Bagman? The colors are a little off on the ladder and the blue money sack...might be due to the color PROM. The ladders should be a real light blue, not green.

Yes, the bonus-levels are on separate ROMs, however I don't know which.
What I would do, was to reseat all ROMs on the graphics-PCB (secondary board), carefully checking them for corrosion, bent/broken pins etc

Thanks for the tip. That was it. I'd popped them out one at a time awhile back when trying to figure out why the board wasn't working right and must have gotten 1 pin out of the socket on one of the graphic ROM's...the one labeled A78 13. After several attempts at getting to the secret room, finally made it and it looked normal. Didn't have my camera handy for a pic though. Hopefully the other 2 look ok as well, but I died before getting to round 30 (the doorways to the secret rooms are on 20, 30 and 40, but you have to be on your 1st life from the start of the game for them to appear)

Just an update to the problem on my board. I picked up some freeze spray from Radio Shack and sprayed all the chips on the board until the problem cleared up. Turned out to be IC26 on the video PCB, a 74LS163. I haven't bought a new one to replace it yet (I need to order it online, since my local electronics shop didn't have it in stock), but when I have the PCB running, as soon as the video starts glitching, if I hit that chip with the freeze spray, it clears right up and looks normal.

I've got 2 Phoenix boards (one says GGI on the board, I think the other has GGI on the screen when you're playing). Anyway, neither melody chip works, one has the little daughterboard with the 7910, the other has the MN6221AA. Most of the Phoenix's I've played where the music works play Für Elise when you blow up the mothership and a different tune at the start. I've seen one that played Greensleeves when you started a game. I don't know what chip that one had in it though, but it was a real Phoenix machine, not a bootleg (although I have no idea if the board itself was original or not)

I think Super Mouse is a sequel. There's also Funny Mouse, which is pretty much the same game as Super Mouse, but different from Macho Mouse. They do share the same characters (Macho Mouse, cats and snakes), the same music, and the slot machine bonus level. On Macho Mouse, you're connecting flags to complete boxes (similar to Amidar or Pepper II), whereas on Super Mouse/Funny Mouse, you're picking up fruit in a maze with ladders and platforms and depositing the fruit in a box at the bottom of the screen.

The 2 boards I have, both are indeed 6116 RAM's, but they're the same size as the EPROM's next to them. Yours is obviously a smaller chip. Most of my other CK boards also have a 6116 RAM next to a bank of EPROM's, at least the Falcon style boards anyway. It must be some sort of RAM though.
