Hacking Ez 3 in 1 expansion rumble compatibilty

[ryan90]

I get that you can run any ds game that requires rumble by enabling it through the 3 in 1 menu, i wanted to play Drill Dozer which is a gba game that supports rumble but i can't get it to work. Do i need some kind of patch or a different program?

When your in GBA mode on a 3in1, you don't have access to the DS rumble function.

any programmers out there wanna try this?, the rumble could work for gba mode aswell, its just a matter of finding the instruction from the gba game and sending the signal to the rumble not that i have a clue how to do that.....

I wanted to do that to about 3 months ago but I guess we're both out of luck with the ez flash

The only way your going to fiddle with the functions is if you can reprogram the MAX II controller chip. I am pretty sure they are using a write once version of the chip to stop people from doing just that.

whats the max II controller chip, i thought it would just be possible to patch the rom into using the expansion rumble, ds homebrew can do it as-well as any ds game.

The chip that lets you change modes with the software code, the large chip on the right.

very interesting stuff, you sure seam to know everything about gba

There was no standard to GBA games, that also applied to GBA flashcarts. Because everyone did it thier own way, you pretty much needed to know alot more than how to use a flashcart. This is even more the rule of things for other systems.

DS flashcarts are where even a 10 year old only really needs to know how to use a flashcart and not need to know how the mechanics of how it worked.
