so the virus ID is stored at the address of the bugfrags eaten value - 4
if you search for the amount of bugfrags eaten in cheat engine, copy the instance in the table and paste it, then adjust the address by -4, you can change what your virus is
regular viruses should end at 42, 43 is marisa, 44 is sakuya
you'll need to save and reload to see your changes, you also need to do this to see EX/SP changes too
chip code is stored at virus ID + 10 or bugfrags + C
this refreshes, so you can see your changes to the chip's code immediately
