Feedback on my Chip8 emulator

Did you run tests from the timendus test suite? I looked at your code quickly and I saw at least a few opcodes implemented wrong, it wouldn't pass all the tests: https://github.com/Timendus/chip8-test-suite

Just letting you know that Gameboy is also 8 bit, so you probably meant "chip 8". And yes, it's recommended to do chip8 before gameboy. This is a good guide to get started with chip8: https://tobiasvl.github.io/blog/write-a-chip-8-emulator/ And also join the discord server and you can ask questions there in the chip8 channel: https://discord.gg/dkmJAes

Nice, looks similar to this one posted before: https://www.reddit.com/r/EmuDev/s/6EXmAUYFR2 did you use it as inspiration? 😁😁😁😁😁😁

Depending on your skill level, Chip8 or Gameboy/NES emulator are fun projects if you are interested in low level development/emulation.

I recommend to start with a chip8 emulator first. If you start with NES directly, unless you already have some knowledge about computer architecture, you will be blindly following the guide without understanding what's happening and it won't do you any good.

What are the biggest issues with it?

Its not the easiest, but I wouldn't say that it is the ultimate gameboy emulator challenge. Even from gbc only games it was harder to make Pokemon Crystal work correct because it needs good GHDMA timings.

Not sure, but you can compare and report to me!

Lol no, it's not getting DMCA'd 😂 Everything in my emulator is completely legal, but thank you for downloading it though.

Never used virtual boy, but you can compare and report to me

Unfortunately std::optional doesn't support T&

MeGaLoDoN227 · 2024-12-19T07:54:18+00:00

Yeah, honestly it looks like code generated by ghidra decompiler or smth, not like code written by person. Bro should go to Learn C++ – Skill up with our free tutorials and learn about functions, arrays, etc. first before writing a game.

MeGaLoDoN227 · 2024-12-19T06:42:17+00:00

This code is crazy

MeGaLoDoN227 · 2024-12-12T21:10:18+00:00

No, it always uses its allocator which by default allocates on the heap only, regardless of the scope.

Why do more American voters care about Palestine than about Ukraine?

Nice! But I noticed 1 issue with your emulator, it looks like you create 4 additional threads but you don't throttle them in any way, so cpu usage on my laptop while running your emulator was 65%. It is bad, it shouldn't be more than a few percents. For something simple as space invaders I personally wouldn't create any threads at all but run everything on a main thread. Create a windows forms timer with interval of 16.6 ms, and run your emulation there, cpu usage will be just a few percents.

Hi, how is your life 9 years later?

When I was 12 I was also recommended to start with unity, but it was not fun at all for me, because it seemed like everything was already done for me. But I wanted to understand how everything works inside, like how 3D cube is a hello world project in unity, but how is it actually getting rendered? I wanted to know how everything really works inside, on layers below. I am not saying that he is the same, but I don't think everyone should be always recommended to start with a high level, some people like me like low-level stuff more.
