Last month (Project Jncota)
* KT-1027/30/33/36 which are based on Xuan Yuan Sword novel series. My party in the latter ended at 78/73/70/68, but with that it was pretty straightforward.
* KT-1057 DQ3 backport — it ends with a black screen. But.... If you press Start it continues, though you cannot escape from the castle (last cutscene loops endlessly).
* KT-1059/67 DQ5 backport — a split backport just like Hengge's FF4. Sad the second cart ends before you access the Sky Tower.
* KT-1060 YS VI Ark of Napishtim — no comment
* KT-1061 YS Oath in Felghana — again, no comment
* KT-1052 YS Seven backport — this time I decided to go far and levelgrind ALL my characters to above 80. This resulted in the final bossfights being a piece of cake.
* KT-1039/42 San Guo something — another split RPG
Recently (Project Nanjing)
* NJ038 Chrono Trigger — Crono only but still had to rely on savestating. Magus' Dark Spell is limited though.
* NJ014 Sword of Mana backport — pretty easy, especially with the best equipment.
No cheats were used when beating all of these btw.
