Frequently Asked Questions

How does this work?

Select the game you wish to personalize from the drop down. Make your personalizations, view the preview on the left, and then add to cart if you're satisfied.

Your customizations will be burned onto a ROM chip which will be shipped to you. Then it's just a matter of swipping the ROM chip on your game's PCB.

Is the modification permanent?
Nope! All of the ROM chips are socketed. So if you want to revert the modification you just remove the personalized ROM chip and re-install the original one.
How do I install the ROM chip?

All of the ROM chips are socketed. You only need a flat blade screw driver or similar tool to help you lift the existing ROM chip from the socket so you can install the personalized one. Check out the following video if you need some guidance.

Does this require soldering?
Nope! All of the ROM chips are socketed. You only need a flat blade screw driver or similar tool to help you lift the existing ROM chip from the socket so you can install the personalized one.
Where do I install the ROM chip?

Each ROM chip type and board location is listed next to the Add To Cart button.

Check each game's specific FAQ below for more details.

Which games do you support?

You can see the list of supported games by clicking the Game drop down.

Note that some games may be listed under different manufacturers or ROM set names. Please ensure you've selected the correct ROM set. See each game's FAQ section below for identification tips.

Also, be sure you have an original/authentic PCB and not a bootleg. These personalized ROMs only work with the original PCB, unless otherwise specified. See each game's FAQ section below for identification tips.

Do you combine shipping costs?
Yes, if you order multiple customized ROMs they'll all ship together in a single box.
What is your return policy?
I do not accept returns. Please make sure you have selected the correct game before ordering. See the game specific FAQs below.

Pac-Man

Which PCBs do you support?
I support original Midway Pac-Man PCBs, no bootlegs! Your board should look like the one below. The second picture shows the 2532 EPROM at location 6J that will be replaced.

Ms. Pac-Man

Which PCBs do you support?

All Ms. Pac-Man boards are simply Pac-Man boards with an auxilary daughter board card attached in place of the Z80 CPU. I support original Ms. Pac-Man auxiliary card, no bootlegs!

The first picture below shows a Pac-Man board with the Ms. Pac-Man auxiliary card attached. The second and third images shows a close-up of the auxiliary card. The auxiliary card contains a 2532 EPROM labeled U7 that will be replaced.

Galaga

Which PCBs do you support?

While Namco originally developed the game, they also licensed it to Midway, so there are two different PCBs. In addition there are two different ROM sets, which brings us to a total of four possible board configurations:

  • Namco rev. B
  • Namco
  • Midway Set 1
  • Midway Set 2

I currently only support Midway Set 1*.

The Galaga boardset consists of two PCBs sandwiched together. First, make sure you are looking at the side labled "GALAGA CPU". Then look for the EPROMs labled "3300B" and "3500D".

* If you have a Midway Set 2 board, or either of the Namco boards, please let me know if you'd like to help me test a personalized EPROM on those boards and/or provide high resolution screenshots for identification.

Why does Galaga require two EPROM replacements?

One EPROM chip contains your personalizations, and the other contains a modification to allow them to load.

Normally, Galaga does a EPROM "checksum" test on boot up to ensure the EPROMs have the correct data. However, this checksum will fail when your personalizations are present. The second EPROM chip includes a modification to bypass the "checksum" to allow the game to boot.
