Am I doing Bankswitching correctly?
So I've been working on bankswitching, trying to make a ROM larger than 32k. I've got it working. I got a 64k ROM. But there's one thing that is bugging me. In the sample provided with the GBDK, there is a function called SWITCH_RAM_MBC1. I found that in my ROM, I do not need that. I have it set up so that my main game is in one bank (savethe27.c), and the levels data is in another (bank11.c). The game works correctly and all, but I am wondering: how is the correct level data being loaded? Here is a link to what I have so far:

Is there something I'm not getting correct?
My avatar is from Nintendo Power. I miss those days, so I decided to bring them back.

Re: Am I doing Bankswitching correctly?
SWITCH_RAM_MBC1 is only required when you want to use external RAM.
