I'm sorry for this long break, but I've had pretty busy schedule last couple of months because of my work and university, but now I'll try to port this camera asap.
For everyone who want to join this process and to help developing this project, I've created project on unfuddle.com and shared developer account.
Here it is: a3100porting.unfuddle.com
Progress for now:
1) CHDK is loading successfully
2) VideoBuffers are correct (we can use "draw" func)
3) Func adresses mostly right (but needed to be checked)
4) DebugPropertySets works well
1) Keyboard. I think than keymask that I've done is correct, but keyboard are still doesn't work.
2) CHDK Menu. Crash is occure when I try to run menu, needs to be investigated why.\
3) Stubs funcs. Not all of them are found.
