(Addendum: Follow along my thought process below with this extra pedagogical material:  https://www.slideshare.net/StephenWylie3/process-of-arcade-rom-hacking  ) An interesting work project, right? I was invited to take my Giant NES Controller to a recruiting event for work taking place at a local brewery.  But you can't just have an NES controller without anything to play, right?  Thus, I pitched a couple ideas on custom games to go along with the giant controller since I didn't want participants playing anything standard either.  The thing they agreed to was to feature the Tapper arcade game, by Bally/Midway in 1983, but modified to show the brewery's logo instead of being Budweiser-branded like it was originally. My handiwork, about 80% done, and with a tiny glitch.  Can you spot the remaining issues? Now you might be thinking Tapper wasn't ever ported to NES, and that's correct.  However, with the help of the MAME arcade emulator and a ...

I could have just asked around to see if anyone had an EPROM validator, but why ask when you can spend several hours doing it yourself, and then several more hours writing in pedantic detail about it?  Of course, I must have the DIY bone... Who still uses EPROMs, anyway? While working on old solid-state pinball machines from the 1980s and late '70s, you might run into a situation where a dead ROM chip needs to be replaced.  Certain types of machines (I'm looking at you, all you Gottlieb System 80's) suffer a problem where coils can get locked on due to bad grounding design throughout the system, and then cause transistors and all sorts of other things on the driver board and even possibly the main board to fry themselves.  In other cases, battery corrosion might leech into the ROM chip and possibly compromise it.  No matter what the case is, you might find yourself in need of new ROMs at some point. Now I could easily go and find new ROMs for my game, order ...
