You would need an EPROM programmer (about $50 at eBay) and a blank EPROM (or UV erase lamp for your current EPROM), although I would keep the old version just in case the new one does not work.

Basically, the procedure is simple: You connect the programmer to USB port of your computer, launch the programming software, select the correct EPROM type, insert the blank EPROM into the programmer socket, load the file that you got from ipdb.org and select "program device" from menu. Then remove the old EPROM from CPU board (with power off), insert the newly programmed one - taking care for correct orientation and power on again. Your game should now be running with the latest software.

If this is a one-time need, your best bet is to buy a ready programmed EPROM or find someone nice Pinsider with a programmer to make it for you.

Also, you will loose all highscores and settings will revert to default when changing ROM.

FLASH!!!! AHAHHHHH!

ITS NOT THE IMPOSSIBLE!!

Unless you think you will program a lot of EPROMs you should just pay someone a few bucks to send you an updated one. I can't speak for your game but some games require updating multiple EPROMs (for example, if you update the game program files you need to update the sound ones too). Usually the upgrade notes associated with the upgrade explain this.

I have arcade games as well as pinball machines and I decided to buy the GQ-4X. This was after using a cheaper made programmer from China that had software which was poorly supported in Windows 7 / 10 and I did not feel like keeping an XP PC or image around. The really really cheap ones are less compatible and what is the point with having something that burns fewer types of EPROMs?

The challenge I ran into being a complete novice at this was (1) understanding which EPROM I can use for each application / size and which ones can be interchanged. Also these days finding the chips is an issue as well. Internet research helped solve all these issues and if need be the message boards have tons of people who really know what they are doing and will walk you through stuff.

Having it is a nice tool but I think I had to use it 6-7 times to break even versus paying someone $10-$15 for what I need and I've just about done that now. I burned my own free play roms for various older games and a few pinball EPROM updates. I also recently fixed my arcade Tron board which had an EPROM data go bad randomly for reasons unknown to me other than it was 30+ years old. I pulled the EPROM and dumped the data and compared it to a known good EPROM and discovered it was corrupt. Burned a new one and it worked.

Lastly if you are into arcade collecting you can use it to identify an unknown game. Pull an EPROM, dump the data and compare to the internet database. Board identified. I helped a friend who hit a warehouse sale identify some oddball stuff.

SIDE NOTE: I played Donkey Kong in an arcade and noticed I was really good at it (compared to my Donkey Kong at home). I discovered with my programmer by dumping my EPROM that I had a "hard" version of Donkey Kong that operators installed back in the day to make the game harder and kick good players off it. I was able to replace that version with the factory original version of the game. Neat discovery and I was better a the game because the only thing I "had" was a tough version and I did not even realize it for about a year.

Checkout Matt's Basement Arcade. I got an updated ROM from them a month ago for BW, and I'm very happy. Great price and fast shipping.
