Program eproms - Help

[BristolMartin]

My ridge racer 2 Wave table Eproms have gone screwy so I woudl like to buy a reader and writer now for 2 reasons.

1. Fix ridge racer

2. Ready Hard Drivin UK version and add to mame.

How do I know which eproms I need for Ridge racer and which reader / writer should I buy?

Thanks

it really depends on your budget,the mcu gq-4x is a usb plug and play reader/writer,which is easy to use,but you have to buy additional adapters to go with it,to read some chips,you would be better off letting people know the makes of eprom and numbers wrote on the chips,so they can tell you which burner they are compatiable with

I don't think Martin has one

Hi Martin

Most eproms will have some text on like below, this will have the chip number on it.

Unfortunatly there is no single burnerreader that will cater for everything so it all depends on what devices you want to burn.

Personally I dont really have may old cabs so I have a Wellon VP-280 which is perfect for my needs as I only tend to play about with newer stuff.

If you can confirm the chip codes this will be the first step.Setch2013-03-07 10:01:33

You will probably also want to invest in a UV Eraser as well a lot of 2nd hand chips already have code on them and will need to be blanked before burning.

From reading the Mame driver source, the ROMs are 1Mb each - but there's no specific mention of what type of Chip they are

Take a look at the chips itself, for 1Mbit Eprom the most common ones are the 27c1001.

Regarding the Eprom writer there are many options, from the most cheaper (chinese) Top xxx writers to something more reliable like a Willem or Wellom.

Both of them, specially the Wellom is a good option for low budgets.

And, dont forget your Eprom eraser:

You can reach every of those items easily on ebay.

Good luck!

Best regards.

Just make sure that any imported EPROM erase has a UK plug and is okay to plug into the UK mains.

Another vote for the Wellon. Sometimes they have problems with 2764 and occasionally 27128, but an external PSU helps greatly.

I thought all of the HD revisions were in MAME now? I dumped a uk set a few years back to send to Jed (the guy who designed most of it) to add to his personal collection.
