Hi All,
I am new to this forum and first of all i would like to thank everyone actively involved in this. It is very nice to have someone else out there to learn.
I am working on a Genesis emulator and at the moment i am trying to figure out what is going on in this game. At the very beginning, i can see this situation:
- DMA is in operation.
- The DMA lasts for more than one scanline, thus forcing me to update clocking in the forthcoming processing.
- After one of the scanline processing, the m68k runs way too far ahead the required clocking (about 400 clocks, which is quite weird, i did not get into it yet).
- In the next scanline, the DMA takes only some clocks for data transfer, and that finally makes game to not work properly as far as i can see.
I wonder if i have to carry on with the extra clocks executed in a scanline for the next scanline.
Any thoughts?
Thank you.
