- The test vbl_clear_time.nes (from the package blargg_ppu_tests.zip) gives me error $02 (VBL flag cleared too soon). On other side, another test 4.vbl_clear_timing.nes (from the package vbl_nmi_timing.zip) doesn't give me an error (passed). However, if I fix the vbl_clear_time by delaying 1 ppu cycle, the other (4.vbl_clear_timing.nes) gives me error 7 (Flag should read as set 2 PPU clocks after VBL).
- I need some help.
