Been working on this for a while, it covers just about everything I know from picking the donor board, prepairing the ROM even ExHiROM games.

17 pages of screen shots and pics of my boards I have made in the past.  Let me know if anything is unclear.

Sweet writeup! Thanks so much for sharing this info.

MrPete1985, I honestly can' thank you enough for taking the time to make this document and all the tutorials you have written. You have truly helped more than you can ever know, and can't thank you enough.

Very nice

Great tutorial, If I had this when I started, I probably didnt ask you that many questions...
Your such a great ressource to NA.

very great guy!

Thanks for sharing!!!

MrPete1985, how can I make an 2J3M works for a Final Fantasy III using 4x 27C801?

I dont know where the pins 2 and 3 of the LS139 need to be soldered =/

I´ve read the document that you posted but still can´t get it to work, can you help?

Best regards,

Rodragon

Any chance you will be doin a NES tutorial?

Glad to see people like this.

As for NES I am planning a short write up when retro stage starts offering NES PCBs but not covering how to use donors

Great write up. Thanks for all your effort!

No help? 

MAD #12 and #13, those points are a21 and a20.

Oh, and the original FF3 is a 24mb rom, so you only need 3 eproms, not 4.

When using an 1J0N to make an 16mbit game with 27C801, where goes the pin 1 of the 74LS139? Because the 1J0N and the 1AON dont have an MAD1.

I´ve tryed to see on the MrPete1985 pictures but no success =/

Join it with the OE hole.

It´s working, thank you so much josete2k.

Awesome post. Thank you for sharing this. The only thing I'd mention, because most people around here are probably not big on sports games, is that NHL 94-95 are still considered by some to be the greatest hockey video games ever made. I'd personally stay away from using them as donors, but to each his own I guess

*bump*

I got a question:
I got a GQ-4x Programmer and TSOP from ST: M29F032
Boards: TSOP ADapter 3 from buyicnow, closed resistors.
The adapter is not recognized until I saw that i need a tsop40 to 36 converter as seen on mmmonkey.
I then bought an adapterboard to be able to program them:
DIP40-DIP36 Programmer Adapter I-1
Item ID00002570

and also a nonassembled version:

DIP40-DIP36 Programmer Adapter II
Item ID00002623

None of my so far 3 soldered M29s are detected by the programmer.
Questions:
A) do i have to close a jumper on the first adapter ?
B) is my 2nd adapter assembled correctly ?
