A friend of mine gave me this board to repair.
I was unsure what game it was (It had Launcher Z written on it), so I dumped the ROMs and couldn't find a match.
Ended up repairing it and like it says, it's called Launcher Z.

It's a 1981 Sigma Orca board, so I tried searching for the PCB online but can't find anything.
I couldn't even figure what game this is a copy of, if it's a copy of anything, or a standalone game made by Sigma.
It's a 3 layer board (the second being smaller than the top board), with the 3 PCB codes being OVG-22C, OVG-32C, OVG-42C.
I have original documentation, but not the cabinet.

If anyone has seen this game (if it's a copy of another) or has any info they could share, that would help a lot.

Uploaded a video to youtube showing the gameplay...

The Dumping Union
ugh

I let a member of TDU get a game that was undumped and they never dumped it. Now it's just being hoarded in someone's collection. They know full well what they were doing. Also what happened to Mr. GunMan?
 
The Mr. GunMan was extremely corroded and damaged, and there's still an effort to try and get data from the chips, but not all DU participants work on things 24/7 and have normal lives too.
It's not forgotten, but requires a lot of work and possible we might never get anything from the roms.

As for the other item, it sold in Japan, for very big money to a very big Japanese collector. I'd prefer not to get into any drama over this as it's not related to this topic. If TDU had gotten it, it would be released.

I've been meaning to try build a rig that holds a chip and allows a Dremel to grind it in very controlled passes and depths, thus allowing one to carefully polish legs or grind the chip body down and exposing the internal metal of the legs to allow soldering to them.

Yup, that's the ticket. Tarnished legs is a pretty easy common one to come across. Sure, rusted out legs is no fun at all, but all it takes a little one-on-one time to get it hammered out. Even in the image he posted, the damaged pins had some real estate left over. I've had to deal with pins that had nothing exposed at all.
 
Interesting.... looks like the background is done fully bitmapped.

I'd be curious if there are character mapped and sprite layers as well or if the entire gfx system is bitmapped.

Not like any Orca / Sigma titles I've seen before.
 
How about using an air eraser to clean legs? For those unfamiliar it's basically a pen like mini-sand Blaster that you can get from Harbor Freight among other places pretty cheap, it might be able to clean legs otherwise too fragile to polish enough to solder into a machine pin sockets and be good enough to dump.

I'll have to try it, I've got a few EPROMs that need leg work.
