Super Game Boy border

So I went ahead and worked almost all my waking hours yesterday attempting to make a Super Game Boy border for GoSub. At about 6 or 7 a.m. or so, I finally got it working.

This morning, I think I fixed the bugs I had introduced when I added in the border yesterday.

This was showing up for a split second (a few frames) upon startup after the border had gone up. So I figured I (instead of the SGB emulator getting the border data and displaying it) must have done something wrong. My solution: Load a blank tile into tile #0. It worked. Next up was the music. I had to change the bank where the goal and title screen music were stored from bank 0 to bank 3. The solution to this was to add a SWITCH_ROM(1) to the beginning to get where the title screen graphics for the Game Boy part were stored.

 

I tested one of yesterday's version on a real Super Game Boy. Since I don't have a Super Famicom, I can't test it on a Super Game Boy 2, so if you have one (and a GB Everdrive), PM me and I'll send you a test ROM.

So now I have 31% of bank 3 free for storing some more level data.

 

The Atari 7800 power cord has finally shipped, Tempo came and worked after a lengthy cleaning. Cosmic Carnage should come today.

That's super impressive!  Where on the Internet did you learn how to embed Super Gameboy backgrounds into your GB game?

I learned via the demo programs that came with my stuff I use to compile Game Boy games. There's a lot of different demos that came with it. I learned how to bankswitch with them as well. Also, there's Discord servers dedicated to Game Boy programming, and I asked for help there as well.
