Almost compatible programs
| Title | Problem Description |
|---|---|
| Final Fantasy II (English translation, Neo Demiforce) | Version 1.02 and 1.03 — graphic glitches during intro, no text during prologue (blue screen without text). Caused by incorrect setting of nametables in PPUCTRL, misuse of PPUSCROLL, and reading of PPUSTATUS to detect VBlank. The issue was discussed in some detail; the author has revamped the entire intro as of March 2015 (not yet released). |
| LAN Master by Shiru | APU DMC causes byte deletions when reading back nametables from $2007 if a dialog is being displayed during a drum hit. |
