TECH: Sega Daytona II/Model 3 Step 2.1 hardware

I purchased an "Emergency Call Ambulance" kit, designed to upgrade a
Daytona II: Power Edition off Ebay.

Seller didn't make sure tubes of chips/ROMS were secure, consequently
an entire tube of chips fell out in box and rattled around in there
all the way to me in Canada.

10+ chips had the hell bent out of the pins. I have managed to
reasonably straighten them, but am concerned about a few of them.

Question is - these appear to be customs Sega ROMS. Can they be
replaced with an off-the-shelf ROM? I have an EPROM burner, not sure
if it can handle chips this big.

They are 32MBIT Mask roms, so yes you can duplicate them, the bad news is
you need to use m27c322_100F1 eproms which cost a small fortune! So not
worth it to be honest, unless you buy a huge qty of them.

Also your Eprom programmer, probably can't handle 42pin 32MBIT eprom.

Thanks for the response. I am going to confirm whether the ones I have
are OK or not. Apparently these are still available from SEGA. They
didn't tell me a price though.
