My eboot used to work. After I added some debugging information, the compiled eboot exceeded the original size (because there was an extra eboot.nb1), so I increased the size of eboot in boot.bib. But...
I used 430 to calculate a 64-bit by 16-bit division, and found that the code increased a lot. Before adding this division, the code length was 0x614, and after adding it, it became 0x1556. I know the ...
Today, I wrote a single-chip stopwatch based on other people's ideas. The display is 00.00-99.99, but only two digits are displayed in the simulation. The other two digits are not displayed. ORG 0000H...
