Hi,
A little point about videl emulation :
I've coded half the stuff (I think).
I encounter major problems for now :
- I've changed a lot of code in video.c, mfp.c, ... (timer_b and hbl
are called from mfp "in hard".
- mouse doesn't move anymore
- it's really slow
- I don't understand well how to code the timer_b
- I don't know how to simulate the 19 waitstates that are taken by
the videl when he loads datas from stRam
- Sometimes, the same line is copied twice, which means that the
videl's got an internal memory, but how much ?
- When and how is it filled ?
A lot of questions and a lot of work before getting something working
for now.
Regards
Laurent
