how to make a 256KB rom?
what I have to do to build a 256KB rom with 16 banks and the MCB1 (this one I've got) but when I try to increase the size it says error: only length of 32768 bytes supported for GameBoy binary. - this is stupid the game I'm building soon is a 256KB game with 16 banks it's just like Wario Blast in a way but with my own engine of Bomberman hacking the rom would be wrong....so I rather program my own using the same sprites.
So how to get GBDK-N to know I'm building a 256KB 16 banked game? I'm confused on this
GBDK-N uses SDCC to build roms - there's got to be a way to change that limit!

If I remember correctly there is no way to make GBDK-N do that.
https://github.com/andreasjhkarlsson/gb … r/examples
In the examples I can't see the banked examples of GBDK, so you're out of luck I guess...

then the game is scrapped then! THERE'S NO WAY A GAME CAN BE ONLY 32KB I'M GONNA Hack it by the way this is how to do MCB1 and 16 banks during the rom making phase
-yo 16 (16 banks 256KB) -yt 1 (MBC1)
There's got to be a way to bypass the limit! I'm not programmin' until there's a way!

GBDK-N does apparently. Not the original GBDK.

GBDK-N Doesn't have banking feature so using GBDK and that I'll be fine making the game at will.
