I uploaded the test program I developed to debug my MC68000 emulator, the MCL68.

I developed it using the Easy68K simulator, which is a terrific tool that is very easy to use.

It exercises each opcode, addressing mode, and flag, going into a hard loop upon failure.

Enjoy!

I just uploaded to GitHub the MCL68 which is a Motorola 68000 emulator written in C!

Below is a test of the MCL68 running 68000 Tiny BASIC on the Teensy 4.0!

I will upload the test code I used to verify all of the 68000’s opcodes soon.

Enjoy!
