beep VS chip8-test-rom

i personally use github.com/faiface/beep for most of my audio playing.

We will be using beep go package to process audio signals and playback sounds. Beep uses oto under the hood for audio playback.

https://github.com/faiface/beep is handy and I've used it for a player. You could extend further to add support for decoding other file types it didn't do (it currentlu does MP3, WAV , FLAC, OGG)

For learning Go, A Tour of Go, and tutorials from libraries I used (Pixel and Beep), as well as a lot of Googleing.

Shamelessly: https://github.com/faiface/beep

I just want the format of the sample data, so that I can process it. Also studying this: faiface/beep...

You can use beep for playing the audio and use a wrapper of youtube-dl for getting the audio urls.

i ran the test rom https://github.com/corax89/chip8-test-rom/ and it said all opcodes are good except for 8XY1 - 8XY5.

So I've been on the fringes of understanding and writing an emulator for a while and decided to take the plunge with a CHIP8 emulator since it's well understood and a good starting point. I'm writing in C# and I've implemented most things to get it working however when I run This test ROM my output seems to stop at AX. I've tried debugging but I can't really see anything wrong with the code so I'm wondering if anyone has seen this issue before and might know what would cause this in general terms.

I was able to get the IBM Logo working(although the position of the logo is not consistent) but when I try to run this test rom, I get a flickering sprite and a bunch of 0x0000 Opcodes.

Hi, I am a total newbie in emulator development. I implemented a Chip8 emulator in JavaScript, finished it, with unit tests. However, when I load a test rom from https://github.com/corax89/chip8-test-rom the display looks jumbled instead of what supposed to be (in that README on that repo).

It may help to know that that first one isn't testing what it says it's testing: https://github.com/corax89/chip8-test-rom/pull/9

For anyone looking to write a CHIP-8 emulator, Matt Mikolay's writeup is less ambiguous:

If you want to target the original Cosmac VIP behavior, corax89's test ROM is good:

I probably did them in numerical order, although it might be useful to pick a test ROM (second option) and implement instructions in the order they're used in that ROM.

I have been going through, implementing instruction by instruction and I've been having difficulty with instruction 00EE. When testing it with this test rom and I've been getting an output of this:

It's really hard to track down the issue with just this video. Have you tried the test ROM? https://github.com/corax89/chip8-test-rom

Also, this ROM is very useful to ensure you handle opcodes correctly
