|

- schematics show 4 lines going from the 58XX I/O chip to the 26XX (starfield generator).
|
||||
Function and operation unknown.
|
||||
|
||||
- Add 62XX custom to machine/namcoio.c (though it's quite different from 56XX and 58XX).
|
||||
- Complete 62XX custom emulation (machine/namco62.c) (though it's quite different from 56XX and 58XX).
|
||||
|
||||
- Is the sprite generator the same as Phozon? This isn't clear yet. They are
|
||||
very similar, especially in the way the size flags are layed out.
