Eprom readers/programmers

[TheGreg]

Does anyone have any links to a good Eprom reader/programmer and/or good info about them, or even how to make them.  Does anyone have any info on what's possible with these?  Is it possible to make changes to a game by copying the data to a pc, make your changes and write it to a new eprom?  What format is the information in once you get it onto your pc?  I've been wondering about this and I can't seem to find any threads that really get into it.

There are numerous prom/eprom readers/burners available ranging from prices of $50 to several thousand dollars available.

I have some programming abilities (Visual Basic and C++).  I can usually handle altering and editing already written code, that's the easy part.  What I'd probably be messing with would be Mortal Kombat 2 or 3.  I figured that someone's already done it for MK2, because there are a few hacked versions out there.  I have one set of hacked Eproms on my MK2 and I still have the old ones that I removed, so I was figuring if I could get the code in some sort of readable format I could compare the two and I'd have a starting point, learn from what other people already did.  But who knows.

So I guess I'd be best off finding the MAME versions of the Eproms and see what I can do with them before I dump some money on a eprom programmer.

If anyone else has anything to add, let me know.  Thanks for the help.

I don't think altering these games is quite as straightforward as editing some VB or C source code!

I think that's an excellent way to try it out.

Thanks again for the help everyone!  I'll let you know if I accomplish anything... cross your fingers.

JDR Electronics (www.jdr.com) has some good programmers at decent prices. Their "Modular Circuit Technology" brand is good. Check out the single gang programmer # MOD-EP1 or the 4 gang unit # MOD-EP4.

i would reccomend to anyone that has an available 16 BIT ISA slot on their motherboard the Needham's PB-10, simple design that works well and can be had for around $50.00

Hi there, hello Ken,
I have a MCT MOD-EP1 but cannot use it because the 5.25" floppy disk is out of order.
I'm buying a second one but I'm not sure that I can use its disk too
Is there somebody who can email me it?
Thanks for assistance.
Kind regards from Normandy.
