I looked at them side by side, when I made that comment. I liked your pcb, thought it was neater, and the transfer pack is good feng shui. The controller connector makes nice kickstand. Building your own stuff and having it work is really one of the top feelings. I understand the decision on not selling or making a bunch of these. Apeshit said it himself, the design has been floating for awhile... The transfer pak pcb looks kinda similar. How off would you say it is from the programmer, off hand?

I like this idea too, I still need one of those, messing around in nanoloop alot lately. This has been a thread of good ideas and revalations,   I am psyched that my weekend is hear, and I have got a good shopping list going now.

Yep. Exactly. Sorry but I won't be selling this.

So this is the zeigler design using this transfer pak's case and cartridge slot? Neat, I'll be down for one.

Oh and just to comment on this. It is exactly the Zeigler design. I just followed the schematic and checked his PCB to make sure all my connections were correct since the schematic doesn't exactly give all the info you need. I may just print out his PCB on some transfer paper and etch my own board because It will be cheaper. But I REALLY want to use this Transfer Pak. At least I could use the connector for either design.

Yeah, about that, a while ago I was thinking... And came up with this:
From the nanoloop website about the usb-midi adapter

Shoot me if I'm wrong. But if the connector just forwards every byte of info that comes from the user port, can't you just write a program to capture that data and say, use the adapter as a virtual gameboy printer to send te pictures to?

Press print on gameboy -> save picture on computer.

If lsdj had a transfer song option, you could theoretically use it to back up your songs as well..

I've got no idea and technical know how to say if this works or not, but it sounds logical to me
Can anyone confirm / deny?

good shots, the wait would kill me in the mean time.

So you can see this thing is perfect for a GBCflasher
It's got the connector, the case and an out line for a new PCB. It will probably be awhile until I finish this but I've ordered most of the parts.

They are different, but still relevant. I was thinking scour the pak guts and see if there is enough to stand alone and replace the controller connector with something more practical. Wishful thinking, if the only good part is the cart connector, but that's still something.
Thanks for posting the pcb Justin, looks like a real beaut, more streamlined when compared to the Ziegler design. Makes me wanna build one ever harder.

Mike, the programs you put together, still mind blowing, and I'm still going to try them out when I get the necessities for it. If it works virtually, it would simplify the hell outta of camera dumping if you can't find a transferer, or go through the gbc to mmc to usb method. I can't get those .sav files moved around fast enough.

Shit, anybody ever dump an mmc or a genius boy?

So here's the PCB I came up with:

It's just about done. Just need to double check everything.

All I'd need from the Pak is the connector. Solder it in place to the board and cut a hole for the mini USB plug.

I can get some pics of the inside of the Transfer Pak later. I've already desoldered the cart connector.

Nah it's cool, Rob. There's no point in keeping anything I'm doing secret after what we discussed.  I'm just making some for myself at this point and I realized the N64 Transfer Pak is absolutely perfect. They're cheap. No one uses them anymore and they're everywhere!
I'll post some pics of my Pak torn apart and some screen shots of the PCB I designed the other day.

Not sure if Justin wants me to say what he's working on publicly, but I'm pretty sure these are two very different things.

What! I'm mentally syncing on stuff everybody is working on lately... Now the cat is outta the bag, keep me posted. That is too good. You got any tranfer pak gut shots? Have trouble finding shots of that. It's funny that this is such head slappingly obvious idea. I'm glad you guys already though of it, from two different ends.

Haha dude! That's what I've been working on! I have the PCB laid out and everything!

Thank You Nitro!

Thanks for responding here, I must have typed the email wrong. I think I got all the answers from my email faster, and with more followups questions than I could comprehend. Just awesome, still. EDIT: I'm just bummed the hardware from nintendo is so dicey, could have been a very practical solution for flashing. I'll pick one up anyway, the guts should have some useful things for at least making a flasher.

When you boot Pokemon Stadium it loads the entire GB SRAM into N64 RDRAM. It verifies the checksum embedded in the SRAM and gives you this error if it's bad: http://lacklustre.net/n64/tpak_ffff.png (screenshot is from emulator).

When you play the game, it loads a subset of the ROM from the pak and loads the rest of the game from the N64 cart. Presumably it has internal checksums for what it expects from the pak.

To answer your question: you'll never get buggy game boy play on the 64, it will just refuse to run.
