Can anyone help me out?
I want this game on eeproms and on a cart.

I heard Mario 2 (US) is a good donor cart for it but I don't know.
Can anyone provide me a how-to get it from rom to cartridge?
I can solder but I need info on:
- What eeproms I must use
- What donorcart I can use
- How to get the Eeproms on the board so I can play it. (what rewiring needs to be done and such (prefer with photo's)

I can provide the rom I'm gonna use. (i believe it's a mapper 142)

Off the top of my head, what I have heard is: If you want to make a reproduction cart of SMB2j, use Loopy's MMC3 hack, not a pirate version.

Ok did a search on Google for it and found it (first or second hit)

Now all I need are the instructions on howto make the cart (rewiring, what eeproms to use, etc etc)
I prefer a guide with photo's and such (step by step)

I guess it'd be the mapper #4 directions on there (TKROM/TSROM). No photos though.

I don't know what the ROM sizes are for that hack. Check here:
http://en.wikipedia.org/wiki/EPROM

Generally you can use a larger ROM, and duplicate the code on the chip as needed.

ok thanks.
this should do it.
Now gonna search for the eeproms.
I really want this!

What about the rest of the pins?
Sorry to sound like a retard but I'm really nw to this.
I have to get an EEprom socket and get that on the mobo, right?
please.....step by step

If you want it to fit back in the cartridge case, don't use sockets. Otherwise, you'd have to cut holes in the case or just not use one.

I'm not sure what steps there are to say that aren't covered in that doc. Except when it says solder X to X, use some wire.

ok thanx.
Now I know enough.
Gonna do this soon!

Yeah, I did this using loopy's patch to MMC3.
Works great!

So how is loopy's patch different play-wise from the pirate? I've got a pirate of SMB2j that allows for a stage select depending on what direction you press when you hit start.

As far as I know, it's exactly the same as the original, except for missing FDS sound in the endgame music.

And no load screens, I take it...

well what about the fact that it's an MMC3 version?
a mapper 4.
a version that can be put on eeproms and on casette's easier then the kaiser pirate

Dudes, I just heard Eprom programmers are dissapearing here in holland.
They said I should use 29xxx type flashroms.
But will the pinouts be the same?
If not I might have to face I will never make a nescart with Mario (J) on it.

The pinout is different, but not by much. There's the write line, and an address line or 2 has moved around.

Don't worry though, EPROMs aren't going away anytime soon. It's already 30-year-old tech. I imagine noone hardly buys new windowed ones (they're damn expensive), but I'm sure one-time-programmable (OTP) ones will be around for a long time. Any good universal programmer will support them.

I don't know about suppliers in Holland, but all these chips are made overseas anyways. heheh.

Buy used EPROMs, they're dirt cheap, no one wants them.
You can find them in old computer boards in junk piles.

I bought mine surplus from a guy in china.
