Qwertie’s SNES Documentation Plus DMA Revision 6
|Release Date||01 January 1998|
|Last Modified||15 October 2017|
Contains essential information for experienced hackers. Covers topics such as joypads, DMA & HDMA transfer, sprites, and registers. Note though, there are inaccuracies.
- Has “big-endian” and “little-endian” mixed up
- OAM high-table bits are wrong
- No information on the name selection bits.
- $2115 bit 7 for writing words is backwards
- BG priority map is only correct for Modes 0 and 1
- Missing $213f effect on $213c/d
- Multitap info for $4218-f is wrong
- Incorrect info: “if a DMA transfer is initiated while a HDMA channel is enabled, nothing will happen.”
- $43×0 bit 7 is not DMA only
- … and probably more
