• curprev 09:4909:49, 29 April 2019 Ped7g talk contribs 51,476 bytes +40 Replacing pipe characters in "shortfx" field with " OR ", because new wiki doesn't survive those, adding few more missing shortfx

27 April 2019

• curprev 19:1119:11, 27 April 2019 Ped7g talk contribs 51,436 bytes −4 Even after 90min of Internet search and thousand variants, I can't get f*cking pipe character into shortfx value (SWAPNIB is currently "fixed" by using OR, many other instructions need fixing to show whole shortfx value)

26 December 2018

• curprev 08:4208:42, 26 December 2018 wiki>Ped7g 49,068 bytes +51 Unless specified otherwise, most of the new Z80N instructions are very safe bet to not modify flags in any way, because they are implemented outside of ordinary Z80 core :/ (but LDWS *does*, so there are ways, when one really wants...)
