I have a 4 eprom Jaguar cart. It has a selector switch and 8 games on it. I'm not sure if it is the same brand of cart as the one in that add but the soldering jobs are a hell of a lot better.

 

No not the same at all.  The multicart is assembled by someone who actually knows what they are doing (retrokidz) and isn't using an acetylene torch and a mallet for soldering.

After relooking at the board it is different. I have NO experience soldering at all and wish I knew how to do cool stuff like this. My son has a few toys that are broken because he banged them and the wires snapped loose from the boards. I have no clue how to solder and reattach them, I need to learn! I'd rather learn tho on a cheap toy than a Jaguar cart tho.

There's a lot of good videos out there to start learning with.  Pick yourself up a decent iron, find some old junk boards/cards with through hole components and get learning :)

Make sure you and surrounding over-lookers wear safety glasses and don't make any quick movements. My buddy was helping solder a Jag board and jerked back quickly. Hot solder landed in his tear duct and we spent the rest of the evening at the hospital but his eye lives! I just don't think he can cry anymore... lol

Besides the laughable soldering job, it also appears that the PROMs are inserted backwards.

 

The notches are supposed to be at the top on a 4-chip Jag cartridge PCB.

This is just a bad copy, or a damaged original version, of the CD bypass cartridge.
