@ -2,12 +2,11 @@ Bugs to fix:
- Left-vram overflow when rendering text
- A few key hits ignored after leaving the application (could not reproduce)
- Lost keyboard control at startup (could not reproduce)
- Back-light issues
- Back-light issues (0xa400012c on SH3, 0xa4050138 on SH4)
Simple improvements:
- bopti: Monochrome bitmaps blending modes
- bopti: Partial transparency
- clock: Compute clock frequencies
- demo: Try 284x124 at (-60, -28) (all disadvantages)
- display: Rectangle-based drawing functions
- tales: Test all font encodings
@ -19,6 +18,7 @@ Simple improvements:
Modules to implement:
- Serial communication
- Sound playback and synthesizing
- Handle errors within errno
Things to investigate:
- Packed bit fields alignment
