9. Alternatives Considered

9.1 Option A: Full VT100 Implementation

Pros: Maximum compatibility
Cons: Complex, large code size, high memory usage
Decision: Implement subset, expand as needed

9.2 Option B: Minimal ANSI Only

Pros: Simple, small footprint
Cons: Limited functionality, poor compatibility
Decision: Implement common VT100 subset

9.3 Option C: Custom Protocol

Pros: Optimized for Dreamcast
Cons: Incompatible with existing tools
Decision: Rejected in favor of standards compliance

10. Open Questions

1. Should we support 256-color mode?
2. What is the maximum practical scrollback size for Dreamcast?
3. Should we implement alternate screen buffer?
4. How to handle mouse input (if at all)?
