Hacking How to make a multi-cart GBA rom?

[Schlupi]

I read about it a long time ago... but I can't find any where to download the program, nor do I remember what it was called.

I am curious. Anybody have a link to what I am talking about?

Just so you're aware, the max size for a GBA ROM is 32 megs, a system cannot address more ROM than that, and many games are near or AT 32 megs already.

Yes, I am aware. =)

Thanks for the info, though. You know what program I am searching for, though, Rydian?

 

[Schlupi]

Also, I put this in the EZ-Flash section because I have an EZ-Flash 3 in 1. I wanted to put together smaller games to use on the 3 in 1. I know it only supports ones up to 32 MB.

Nope, just didn't want you to waste your time if you were after combining Mother 3 with some other stuff.

Lol yeah. I saw a bunch of people wanting to do that. =P

I actually just want to combine Golden Sun and Golden Sun The Lost Age together.

8 MB + 16 MB = Just fine.

 

[Schlupi]

Been searching everywhere the last hour... Cannot find the program I am looking for.

This is pretty frustrating. Why is it so hard to find?

Would PogoShell work? How the hell do I use it? >_>

I dunno.

I think I read something about one of the EZ-Flash slot1 cards being able to do this, but I don't think it's on the current firmware for it. (All conjecture and vague memory)

I'd love to be able to do that myself, though. Just bought a bunch of 3in1's to use in my GBA.

Yeah, so PogoShell can't do it.

Any you seem to be right -- just came across a post by how_do_i_do_that talking about how the EZ Flash V can do this.

But I dunno. I have an EZ Flash Vi but I do not know which firmware can do what I want... or if there is any other way.

Thanks for the info. I guess it puts me one step closer.

Found it!

Edit: Well, for the EZFlash V slot 1 solution, anyway.

I found that topic, just now as well.
It has the info I need. I just need to know how to use it. I got the EZ-Flash Vi Kernel 1.09 Beta 11 (latest with Multi-rom feature) just need to see how to use it on the EZ-Flash n3 in 1 now...

Gonna fiddle with it and try to figure it out.
Thanks for the link.

I'll tell you guys what I find.

EDIT: Yeah. It is the slot 1 solution. But when the game is written to the slot 2 NOR memory it saves it, right? So if I make a multi-rom on the EZ-Flash Vi it would save, and be usable on the GBA, right?

 

[how_do_i_do_that]

Most of the multi-rom tools were flashcart specific at the time. Most of the stuff you want to find were all located on gbadev.org. The majority of the links you find will be dead though.

The reason it is flashcart specific was that that multi rom bin files had to know things about the SRAM and NOR of the flashcart to make a via lumped gba file. There were some generic ones, they kinda sucked because it tried to cover too many flashcarts.

The older EZ Flash V firmware supports GBA cheats and multiboot. I still use it to load multiple roms on my 3in1.

I can think of around 6. Not sure that constitutes "many."

 

[Rydian]

They tend to be the popular ones.

OK... So does that mean that it will make the multiboot for me to write to my 3 in 1? How do I set that up? what do I need to do with the rom files? do they need this "multiboot" patch thing that I see in some of the programs?

I am still confused.

 

[Schlupi]

Ok. So I put the old Firmware on the Vi... and I cannot even figure out how to boot the GBA game, let alone create a multiboot rom.

Anybody know how to? Still never got an answer to how this works.

 

[how_do_i_do_that]

Your confusing multi-boot with the EZ Flash V multi-rom option for the 3in1.

Multi-boot allows you to use a bootable menu system on the GBA device independantly.

The multi-rom option is a EZ Flash V slot1 dependant menu system to access roms on the NOR of the 3in1.







To use the multi-rom option you have to enable it first in to settings. Once you do that, continually add roms to NOR and it will show up as a menu like this:

Yes! Thank you. I appreciate the help. I finally got it working. Now I can have Golden Sun 1 & 2 on one cart on the go.

Thanks guys.

Hey Schlupi! I'd love to hear how you managed to accomplish this!
