active minimig coder

Sorry my english is not that perfect... I try to explain all this in my (translated) words. Its pretty complex to discuss that stuff via text only.

I will check things out and report (hopefully understandable) the result here.

(WTF is my HRM?)

is my - all alien to me.

Yep I did unfortunately I also dont have a HRM to look at.
Right now Im working out that ddfstart/stop problem. Seems to be a combination of 2 signals. Bitplane data fetch stops but bitplane DMA is still working on until end of display line. That may explain heavy distortion in my beloved Vision Megademo IV and other games/demos.
I'll keep you informed about any progress.

Hello RedSkull,

thanks for your email and explanation in this function.

I also think overscan must be handled intelligent instead of fixed point. I tried to change the sol pointer, even in the slightest change has fatal impact to the generated VGA signal and make my TFT go crazy
Set to 454 the picture appears for 0.2 sec and disappear again. Set to 452 will show no picture at all!

I belief in time your ECS implementation will do this job as in real Agnus chip

Who is also coding the FPGA core here?
There are a few things I want to change and/or add to the minimig.
For instance:
- make reset funktion in OSD working
- add OSD control via joystick in port 2 (up/down/fire) when active
- simulate left and right mouse button on key "print" and "pause"

If somebody could assist/help, it will be welcome!
