Matching Roms

[Servo]

Hey Guys,

I've got a technical question and i was wondering if anyone could help me out. I just picked up what i think is a bootleg pac man or ms pac man board off ebay for a few bucks the board is labeled pac-3. I removed a rom and tried to match it against hamsters online rom ident but im having a problem. the rom reads fine but when i save it to compare it to the data base it doesn't recognize the rom. i figured it was probably a bad rom but i took one off a working ms pac man board and when i saved it and compared it to the data base it still doesn't recognize it. when im saving the rom ive saved it as both a hex file and a bin and still no luck. can anyone tell me what im doing wrong? i am using a genius g540 programer. any help with this would be appreciated...

looks like there are a lot of roms that are not supported by the genius g540 universal programer. i cant believe it doesn't support the roms from ms pac man (HN462532G). i can get them to read using other rom settings but they don't read the whole thing i guess. can anyone suggest a good eprom programer that supports most of these devises.

Well, the one I use is the EMP-10. It's old school but it always works. I have heard hit or miss type stories with the newer USB ones. I never have problems with mine.

yeah, is it it on ebay, its a little pricey but it looks like it supports a hell of a lot more roms then the one i got. might have to bite the bullet and buy it. i just dont understand i though the 2532's were the most common

Well, it depends on the manufacturer too. I could never burn TI 2764s in mine. So, it could be a certain brand that your burner doesn't support.

the eproms are not listed in the device list, you can use a general 24 pin like a 2716 or 2732 but its not matching the roms from romident, the checksum is all wrong.
