Homebrew About GBA Emulation -Don't get mad, hear me out.

[Arneshie]

Hello, this is my first post. Anyways, i had an idea.
Does anyone remember, MEGAMAN ZERO Collection? the NDS game which contained 4 GBA games? Well i was just thinking, it's a port, right? Well why don't we port some of the best GBA Games or something, or create some sort of software to port a GBA game to NDS? Wouldn't that work? Sorry if this is a really bad idea, but dont flame me please!! Im just thinking here

Thanks for your time!

every gba game is compiled differently
'nuff said

 

[Overlord Nadrian]

Sorry, but due to internal hardware differences in the DS and GBA, this is impossible.

 

[Arneshie]

Oh i see, thanks.
Err to the second person who posted, if the hardware differences are so great, how come Megaman Zero Collection can run? im just asking, cause i already know an EMULATOR wont work, but im talking about porting a game.

It would be possible...

But seeing how difficult it is to get a game translated (little code editing then script translation), I don't see a group of people --all of whom have the editing skills needed to port the game-- staying together on the project long enough.

 

[Zood!]

Well why don't we do xyz

Yeah right... you go ahead, and if you're half-way done, the rest joins in

GBA: the cardridge is pluged on the same bus as the ram, it has a high bandwight.
NDS: the Slot1 cartridge has its own bus, but slower as the ram bus of the GBA. But GBA games needs this fast bus, so you need to put the whole rom in the ram of the NDS, but the ram without expansion isn´t big enough. As for professional ported games from GBA to NDS, they rewrote the access system and the filepointers and compiled it, because of that, simply injecting a other rom wont work, because every rom is different, with different filepointers and so on...

someone correct me if i´m wrong

Also in order to " port " a game you need the SOUCE code and only the original developers have it.
Without the SAUCE, (source code ) no code to work with=no port.

cant you get the source by unpacking the rom?

Most of the time, the source is encrypted to keep hackers out.

I'm pretty sure that a small team could eventually port a GBA game to the DS and do a pretty good job of it but it would take a hell of a long time and no one would want to spend that much effort when other better options exist like slot 2 cards. OK DSi owners will loose out and have to resort to emulation but im sure most people would prefer work going into emulation which could be used for all GBA games instead of porting a single one

Compiling an app and encrypting something are two entirely different things.

No.

DSTWO can emulate GBA ROMS can't it? I believe there's also a team making an n64/PS1 emulator as well for said flashcart.

The DS is completely capable of playing GBA games on it's own. Problem is hardware config. Anything Pre-DSi, you're better off with am Expansion port. DSi, get a Supercard. Other methods require way too much hardware adjusting to be worthwhile.

Capcom made the original MMZ games. They are fully capable of recreating their own game. Which is why MMZC exists.
And you can't really port a game without having the code (read emphasis in last sentence).

Link please?

 

[Bunie]

the DS cannot emulate 64. if the card has a rather fast processor built into it, that runs its own process to interpret and convert the 64 rom on-the-fly, fast enough to be playable, a card like that would cost ALOT of money, more than the DSTWO.
