Hello everyone, this my first post in this place and i hope which this is not the last and i can contribute to community too =)
I am working in new CPU to my NES emulator, i am very novice on emulation and i had some doubt(i used nesdev wiki, this help much) and i finished the new CPU which i written in ARM Assembly, but there is some bugs in some games. So i used NEStres to check some problems and it give me these erros:
ASL - Error in Z-Flag
ROL - Error in Z-Flag
ROR - Error in C-Flag
ABSX - Error in Wrap
ABSY - Error in Wrap
The Flag is easy to fix(i think) but the problem now is with Absolute Y and Absolute X, these wrap, i checked many times and re-write many times the Addr of ABSX/ABSY and never change, someone can explain me more about it ?
Regards =)
