MicroCoreLabs
Ted Fried's MicroCore Labs Projects which include microsequencer-based FPGA cores and emulators for the 8088, 8086, 8051, 6502, 68000, Z80, Risc-V, and also Typewriter and EPROM Emulator projects. MC...
This function is called too often wrongly to retrieve immediate values, displacements or offsets in an instruction. You should use a MEM_READ_BYTE (3 T-states) and not an OPCODE_READ_M1 (4 T-states)...
Hey, for better reach of the community, I would like to suggest to add the following topic to the repository: `motorola-68000` [How to do this](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/classifying-your-repository-with-topics#adding-topics-to-your-repository)
Using the `MC68000_test_all_opcodes.X68` test rom, the MOVE from SR test does ``` move #$275A, SR * Initial value move SR , d0 cmpi.w #$275A , d0 ``` But from the...
Only compile tested, I have no teensy4.1 MCL kit yet. Lots of later improvements possible, like checking where screen ram actually is runtime and so on, but this should be...
Just a thought, have the C64 version use writes to $d030 control which cache mode to use, somewhat like the C128, SuperCPU and Ultimate64 kits do to switch between 1...

The comparison operator for "BLTU" in riscv.c (l. 91) should be "=" (this line is identical to the "BGE" line below it except for the instruction name): if (opcode==0b1100011 &&...
hi, MCL64 seems to be a great thing but i got some errors on checking a working c64 board (250407). Before I started with MCL64 I was checking the hole...
I have a somewhat naïve question: is the XTMax available to purchase as a ready to use product I could buy? I'd like to give it a try in my...
