DOSBox-VirtIsa

This fork focuses on building an emulation environment for a custom ISA card.

Purpose of this fork

• Keep a DOSBox-based runtime for ISA development and experiments.
• Add a dedicated ISA emulation insertion point that is easy to tune (src/isa/isa.cpp).
• Provide an automated GitHub Actions compile check.
