does anyone know what is wrong with my chip-8 emulator?
i ran the test rom https://github.com/corax89/chip8-test-rom/ and it said all opcodes are good except for 8XY1 - 8XY5.

CHIP8 Emulator Assistance
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.

How to debug Chip8
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).

In what order should I implement the CHIP-8 instructions?
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.

This happen to anyone else (Chip 8)
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:
