Download to real Gameboy.

I have an Emulator for Gameboy on PC.

I can write software well. Did Z80 assember and Z80 Modula-2 for industrial controllers 20 years ago.

I have also 3 flavours of GB in the house


I have some sort of GameBoy Software development kit.

I want to write some stuff and use it not just with emulator (pointless, I can write actual PC games and SW), but put it on a cartridge.


There *USED TO BE* a special cartridge with a PC interface /link that let you do this, can it be got?

The other option is an old 486:
* The Bios EEPROM is about 128K bytes
* A program can load anything you like into it.
* When running the 486 doesn't use it, it is only for boot.

so:
You make up a daughter board to go in the 486 Flash Bios socket with two sockets on it (one a ZIF) and a change over switch on the CE / CS rom pins.

In one position you boot from original BIOS ROM, toggle switch and then run the DOS flash upgrade utility that has a Gameboy program instead of PC bios file.

So then you need a cartridge with the page decoder and a ZIF for the Flash ROM. (Same ROM definately does work in 486 and Gameboy). So does anyone sell *THAT* usefull plugin either?

I don't have any PCB making gear nor time to do a layout. Though the cartridge is not hard.

The PC daughter card I can do in a few hours actually on veroboard / stripboard easily by making it a double deck with the original ROM in lower stripboard socket. Only two tracks and three wire links.

Not sure exactly what you're intending to do.
But you could try look around http://www.lik-sang.com.
Failing that there might be a helpfull soul around here to lend a helping hand.

I want a gameboy compatible re-writeable cartridge I can download to from PC so I can run software I write on a real Gameboy.


Such a thing used to be sold but Nintendo didn't like it as it was usable to upload games from commercial carts to PC and download anything from PC to itself. The orignal obviously must have had a slot to take a second cartridge or something. I don't need that, I don't want or need to read commercial ROM carts.

Not quite what I'm looking for as it doesn't work with GameBoy Color or GameBoy Original.

Description

Important: This is the only genuine product from Jeff Frohwein. Don't believe in other companies selling MBV3. They are just cheap imitations. The MBV2 at Lik-Sang is the only one from the original developer. It supports not only uploading MB files and is faster because a expensive high speed CPU has been used, but also supports the GBA UART communication mode for debugging! It has the additional serial port which other "clones" don't have.

The MBV2 (MultiBoot Version 2) is a cable that connects to either a PC parallel or serial port and to the link port on the GameBoy Advance itself. It allows you to test small GBA programs (256K bytes or less), that you have created yourself, on real GBA hardware. It takes advantage of the fact that each GameBoy Advance has a built-in boot algorithm for loading code over the link port into external WRAM (256k bytes) and then executing this code. (External WRAM is actually inside of the GBA itself.) As such, no cart is required to be installed in the GBA to use this cable.
