**Jotego Updates**

Find the difference.
Both images come from simulating an upcoming FPGA core. But one of them has been generated with a memory dump of the core running on an actual FPGA. This hints to a bug in the M6809 CPU logic 1/3 pic.twitter.com/mh4GZKduzN— jotego (@topapate) March 17, 2022
The CPU must write a specific bit in the video RAM. When synthesized the CPU is writting at bit 4. When simulated, the CPU writes at the correct bit 5 position. Nasty, isn't it? 2/3

The next step will be to isolate the CPU instruction responsible for that bit write and check the Verilog code associated to it. Then try to write it in a way both simulators and synthesis tools like. BTW, this isn't this week's JT core.
— jotego (@topapate) March 17, 2022
This is solved now. It wasn't a compiler issue but a settings difference. There are three undocumented test bits in the game and they were not set in the same way. One of these bits seems to change how the GFX ROM is mapped. https://t.co/w0xYJdGtFp
