-DMA default "add mode"
-----------------------
-
-``dspasm.exe`` has a bug where, despite the SCU manual
-(ST-97-R5-072694) claiming that the default DMA "add mode" is ``1``,
-the generated code is "add mode" ``2``.
-
-This bug is documented in "Sega Developers Conference Conference
-Proceedings March 5 7, 1996" on pdf page 48, printed page 3-14,
-slide 25. However, Sega of America did not fully understand the nature
-of the bug: patching ``dspasm.exe`` output is not necessary, because
-``dspasm.exe`` does in fact generate the correct code for the ``DMA1``
-mnemonic.
-
-In short:
-
-- ``dspasm.exe`` assembles ``DMA`` as the equivalent of the ``DMA2``
-  mnemonic
-
-- scu-dsp-asm assembles ``DMA`` as the equivalent of the ``DMA1``
-
-.. note::
-
-   It is unclear which of these is correct. A future version of
-   scu-dsp-asm may change this behavior.
-
-   The documentation, dspasm.exe, and the real SCU DSP are each
-   representing this in a mutually inconsistent way.

+=================================================================
+
+DMA default "add mode"
+----------------------
+
+Contrast to what is written in the SCU manual (ST-97-R5-072694), the
+default DMA "add mode" for both dspasm.exe and scp-dsp-asm is
+``2``. E.g:
+
+- ``DMA`` is a synonym for ``DMA2``
+  
+- ``DMAH`` is a synonym for ``DMAH2``
+
+In "Sega Developers Conference Conference Proceedings March 5-7, 1996"
+pdf page 48, printed page 3-14, slide 25:
+
+   You need to modify your object code, either by hand or with a
+   custom tool.
+
+This is completely incorrect, and both scu-dsp-asm and dspasm.exe will
+emit "add mode 1" via the ``DMA1`` and ``DMAH1`` mnemonics.

+DMA "add mode" and bytes

+All of the documentation you have read is invalid; here is the correct
+relationship between DMA "add mode" mnemonics, and the number of
