- * The 0x80xxxx and 0x40xxxx ranges are aliased to each other, no idea what
- * the differences are, so for now just use 40xxxx for both palette and cursor
- * sprite access.
+ * Turns out 0x40xxxx and 0x80xxxx access the same registers, one difference
+ * is that through 0x80xxxx we can read back at least some values, so use
+ * that one
* The _POS, _INDEX and _DATA registers work exactly like on HCRX
