 |
|
Current WIP for the Minimal SDK 0.C (as November/29/2006)
Greetings from darkness...
PS: hope you like it :-)
| Code: |
What's delayed for 0.D:
=======================
- OSD layer
- fine scaling (post scaling)
- support for DaveC's pad configurations (model 0,I,II,III,IV)
- rotation
- usb mouse
- usb keyboard
- custom tv modes
- custom framebuffer size
- single buffering support (una-i's request)
- eeprom reading support
What I'm doing right now
========================
- write new documentation (argh!)
- fix RGB windows (joanvr's bug)
- test usb joystick
- test gp2x_file handling (& tcp/ip wrapper & file selector)
- test PSD image handling
- test hardware blitting
- test yuv/rgb scaling fix (@ lcd+tv & new scaling params mode)
- test tv video output (ntsc & pal)
- test I2C support
- test uninstallhack
