Instruction 0x3000 and jump instruction repeating on almost all games on CHIP-8

Why doesn't gcc link an SDL 2.0 C project? (macOS)

QUESTION

Instruction 0x3000 and jump instruction repeating on almost all games on CHIP-8

Asked 2020-Jul-14 at 16:04

I am new to emulation and figured writing a CHIP-8 interpreter would get be started. However, I am facing an issue. When running a game, like Brix for example, it draws the game no problem (the paddle, etc.) but, after it is done, it just gets stuck in a loop of 0x3000 and after that, a jump instruction that jumps back to the 0x3000. It is clear that 0x3000 is false and that is why it is looping, but I can't figure why that is for the life of me.

Screenshot of the game and the Chrome devtools console (the game is Brix, taken from here): https://i.stack.imgur.com/a0wNM.png

In that screenshot, in the console, you can see the 0x3000 is failing and going to a jump, and that jump goes back to 0x3000, and the cycle repeats. This happens with most, if not all games. I suspect is has something to do with the delay timer, since 0x3000 is checking for v0 === 0, but it fails, and goes to the jump instruction.

Here is my main CHIP-8 class:

It appears that your issue is that you are incrementing the PC again after assigning it in the JMP instruction (0x1nnn) (You can see the discrepancy in your debug output). So after the current executeOpcode cycle, the execution returns to this.step and hits this line:

Why doesn't gcc link an SDL 2.0 C project? (macOS)

Asked 2020-Feb-03 at 19:52

I wrote a simple Chip-8 emulator in C (mostly taking inspiration from this; to be honest, just rewriting it in C). It uses SDL 2.0, which I definitely have installed.

As I tried compiling the files (gcc main.c chip8.c -o chip8), I got this stack of errors:

Why doesn't the linker work with this? Are any other compiler flags required?

Yes, you need to tell the linker which libraries to link against, e.g.:
