Re: CRT Safe Area / Overscan?

Hmm, okay. I guess I'll just roughly follow something like that or eyeball it compared to other games. Thanks for the reply!

CRT Safe Area / Overscan?

What's the general accepted "Safe Area" for important game elements when viewing a game on a CRT? I can test against my own CRT (a sample size of one is never ideal), but I would like to know general conventions. I looked through this thread, and didn't really see a consensus, though I certainly may...

Re: CRAM addresses?

Ah, okay. Thank you so much for the detailed explanation! I was still tripped up a little by palettes being split in two, but I got it sorted out. For anyone in the future searching for this, here are examples: "move.l #0xc0000000, 0xc00004.l;" //Instruct VDP Control Port (address 0xc00004) to write...

CRAM addresses?

Hello everyone! I'm trying to dip my toes into some in-line assembly (in SGDK) to try to change a specific color during a horizontal interrupt. This is my current simple code: asm volatile ( "move.l #0xc0000000, 0xc00004.l;" //Prepare VDP to write to. "move.w #0x007E, 0xc00000.l;" //Write Orange (0B...

Re: Do you need tutorials ?

I have no idea if this is the best approach (I'm learning C simultaneously), but here is what I've done to control some animations: I have an animationTimer variable that I increment at the very end of my main() function. if (animationTimer > 59){ animationTimer = 0; } else{ animationTimer++; } } Th...

How do I use the Spade character?

Hello everyone! It's been inspiring watch everyone develop and experiment with my favorite console of all time. I do have a question that's stumped me though; how do I actually use this highlighted character? font_default_Spade.png I've tried using "♠" in Visual Studio Code, but when I compile, I ju...
