Nice! This is something like I envisioned after I started entering games for the switch database at http://www.pinitech.com/switch_database.php -- seemed like it would be great to have info on the connectors, wire colors, ICs and possibly mark issues and have it make suggestions where the problem might be. With today's technology it just seemed like the next logical step to put switch and lamp charts into a database that was more user-friendly to make it easier when diagnosing issues while working on a game. Great to see someone with iOS/Android experience that could make it happen!
I'm not sure if it'd help but if you want a dump of the database I've created, let me know. It'd just be switch numbers and names, but I have a majority of the older games in there. Your app would actually be an awesome companion to the switch matrix tester I sell.. especially if you could toggle on/off the cross-hair and the small numbers that identify the switch number on the tester (for games that don't fit the silkscreen numbering) like on my switch database
Great job! It looks like it'll be an awesome troubleshooting aid!
