My First Reproduction! Super Mario Bros. 2j!

[Jrmoreno]

Thats awesome!

I agree 100%. I was so excited I didn't even notice until I took the pics. In my defense, the donor carts are all eBay purchases.

No excuse! All foreign carts shall be cleaned before bringing them within spitting distance of your machinery!

Cool!

That label is really awesome looking.

Almost gives me the inspiration to buy a soldering iron and do something with my old BurgerTime cart, just for the hell of it.

What ROM are you supposed to use for this? I used the following rom and couldn't get it to work....

Super Mario Bros. 2 (J) [b1].nes

I assume that what I tried to use was the original file that hasn't been hacked to work on a standard mapper?

The Mapper 4 hack uses 512kb prg and 8kb chr. The OP is using a 27c020 on prg which is 256kb, so he isn't using the mapper 4 hack. He also has a 32 pin EPROM in the chr slot, so he isn't using a 27c64.

Thanks in advance. Any help is much appreciated.

I have several repros for nes, but I have never taken one apart...Will I find similiar wiring in all of them? I was under the impression it was done without wires? but now it all makes since. My Contra(japan) is one heavy cart as is Yie Air Kung Fu!

Nice work..I am envious!

The correct ROM to use for Super Mario Bros. 2j is Loopy's MMC3 Hack. The second thing is to use the correct donor cart. For example, I've done this with Bo Jackson's Baseball and Bill Elliot Nascar Racing. This is a list of donor carts from the nesreproductions website:

Bill Elliot Nascar
Bo Jackson Baseball
Bugs bunny birthday blowout
Dracula (imagesoft)
felix the cat
gauntlet 2
home alone
image fight
jurassic park
kid klown
king quest 5
MC Kids
Roundball
Silver Surfer
Star Wars
Super Mario Bros 2
Super Mario Bros 3
Tetris 2
Tiny Toon workshop
where in time is carmen
where's waldo

Let me know if that gets you in the right direction or not.

You'll find all those wires in MY work. LOL! I've read that some games have a 1:1 pinout. Those are probably mostly common games or games you wouldn't want to repro anyways. Some people also have custom PCBs that they re-route everything correctly on, then solder a tsop chip to it. (I'm totally not there yet.)

Roms tagged with or [bx] (where x = 1, 2, etc) are known *bad* dumps.

I have made several repros in the past, so I usually know what I am doing. I used MC Kids, but I obviously used the wrong rom. The mapper 4 (mmc3) hack that I found uses 512kb for the prg, so it can't be the same one you used. Does anyone know where to get the correct rom?
