Ah hell yeah that's way better thank you! I can't find the exact chip on that site. I searched the number and got a few results. I'm assuming they're the same chip but different manufacturer correct? Also the number you gave me doesn't match mine. Is that a mistake or are they just compatible?1- go to www.buyicnow.com
2- you need 3x27C4096 chips, put them in your cart
3- add eprom burn service for 3 eproms, then buy.
4- locate the 3 files 21-22-23 in the mame romset you want to upgrade to with the same game region as the game you want to upgrade and send them by email to buyicnow, ask him to burn the eproms with these files
5- wait 2-3 weeks, upgrade your roms, you're set
I ordered some parts and we'll see how it goes. Thanks archimage.
