Investigate branching #270

Closed Rodrigodd closed 8 months ago

Rodrigodd commented 8 months ago

Some changes I made while investigate the problem with the branching. The fix were applied upstream in https://github.com/msinger/dmg-sim/pull/1 (commit https://github.com/msinger/dmg-sim/pull/1/commits/b94e5675cf267df80fe0bae02702a5695d77c7fb).

Also included my notes in investigation.md. I can drop that commit if you prefer.

The next problem in quickboot.bin appears to be in the JR instruction. I will investigate about it tomorrow.
