RE: need help with dreamcast HDD IDE
Reducing the size will not help against the protection, since the required checksum we can't get from part of original BIOS, need all data...
At least it does not alleviate the problem, so it makes no sense.
I think it's the second option, since the first implies simultaneous reading of BIOS by processor and holly, and this obviously does not good, just may be a conflict. And it would work longer, then it was easier and safer to use a timer.
I have an idea ... Maybe instead of reading, try to write data onto the bus, maybe Holly does not understand the trick, because the data will be on the bus.
Although it would be too easy ...
