• curprev 15:5415:54, 15 March 2024‎ Fiskbit talk contribs‎ 18,960 bytes +773‎ Adds a cycle count table for various DMC DMA cases to the synced reads section. This is more relevant and less misleading here than on the APU DMC page.

• curprev 00:0800:08, 14 January 2024‎ Fiskbit talk contribs‎ 18,187 bytes +109‎ →‎DPCM Safety using Repeated Reads: Explains why repeated reads have a cycle budget.

• curprev 09:5909:59, 13 January 2024‎ Fiskbit talk contribs‎ 18,078 bytes +30‎ Notes that the DPCM bug is fixed on PAL.
• curprev 09:5309:53, 13 January 2024‎ Fiskbit talk contribs‎ 18,048 bytes +4,825‎ Adds a DPCM Safety preamble explaining the bug and limitations common to all approaches. Adds (comprehensive?) pros and cons for each approach. Cleans up the synced reads explanation.
