5.4 Dreamcast-Specific Considerations

1. No Unicode Font: Dreamcast BIOS font is ASCII-only
2. Limited Colors: PVR2 texture formats affect color depth
3. Texture Memory: Font textures must fit in VRAM
4. Performance: SH-4 CPU is the bottleneck, not PVR2

6. Testing Requirements

6.1 Unit Tests

• Escape sequence parsing
• Cursor movement
• Screen clearing
• Scrollback navigation
• Buffer serialization
