There are far too many roms available to sit down and list everything available.
If you can provide a rom image that you need burned, I have a flat rate per chip type to burn them for you.
This service is not limited to Arcade and Pinball machines, many electronics utilize standard IC chips.

Out of stock or chip is not even listed here?

Even if I do not have the chip type listed or in stock, please contact me as I can probably get it in.

If your in a hurry and local or don’t mind shipping it to me…Sometimes your existing chip can be fixed by erasing and reburning if it’s not a physical issue with the chip.
