I know that the Stairs Glitch is where you climb 70 stairs and certain things happen. For a credits warp, you need to get 56 houses, 57 heals and 201 Pures (the way to get 201 is underflow the pure-count and drink 54 in battle.) Use down to 32 houses, save only with the last one and jump to your inventory (with a code) to get the credits rolling.

Sounds like you have the tools already with the pastebin and the notes and stuff. Here's a video of an RTA playthrough of the credits warp route so you can visualize the setups. https://www.youtube.com/watch?v=eo0CtjU_T_c

Not sure how interesting this restriction will be, but it is a thought. "No run away." For sake of rules interpretation, selecting run is allowed, but successfully running is not. Save-reset trick will be a side-stepping of the proposed rule in the effort to avoid encounters without technically running away. This will only for the overworld, at least, so I'll leave it up to others to decide on whether to include "no reset" on top of "no run away." I'm curious what the implications are for never running away. Sure, you'll get more levels. You'll probably manipulate fewer enemies where possible for faster fights. How avoidable is damage with the limited RNG? Will it be worth it to have more than one standing character? Does this restriction give better variation for this game? At the moment, I find this thought interesting. I have no intention of following through with the thought, but I would share it in case someone else finds it interesting as well.
I'd like to see a run with those restrictions. Having those restrictions would also make money routing more interesting too. As for the length, I believe it would take less than 2h30m. Would also make any RPG run more action packed.

NES TAS of 2020 Glitchy TAS of 2020 Speedy TAS of 2017 NES TAS of 2009
従来より32階層でのメニューオープンでゲームがフリーズすることが知られていました。 32回の昇降後に単にメニューを開くだけだと"40:RTI"を踏んでしまうため、$0312に到達することが出来ません。 
      00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
0300: 10 05 7A 10 06 00 07 0C 05 06 40 40 04 04 30 40
0303:10 06     BPL $030B
030B:40        RTI
しかし予めどこかでメニューを開いていると$0300-$030Fの上書き処理が完了され、$0312に到達できるようになります。 
      00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
0300: 10 05 7A 10 06 00 01 13 02 00 80 7A 80 7A 80 00
0303:10 06     BPL $030B
030B:7A        NOP
030C:80 7A     NOP #$7A
030E:80 00     NOP #$00
0310:01 00     ORA ($00,X) @ $0000 = #$00
エンディングシーケンスに移行するにはbank:0Dに切り替える必要がありますが、幸いなことにそれはbank:0Fのカオス戦後のループ処理の中に存在します。 
0F:C93A:20 2B E9  JSR $E92B
0F:C93D:A9 0D     LDA #$0D
0F:C93F:20 03 FE  JSR $FE03
0F:C942:20 03 B8  JSR $B803
0F:C945:4C 3A C9  JMP $C93A
このループのどこかに飛ぶことが出来ればカオスを呼び出すことなくゲームを終えることが可能ですが、0xC9や0x44以下の文字は登録できない上に7byteしか自由に使えないので非常に困難です。 そこで、スタックに既に積まれている0xC9を再利用し、0x38-0x44の値を"48:PHA"でプッシュすれば"60:RTS"でエンディングシーケンスへリターンすることが可能になります。 条件を満たすためには A = X = 0x38 or 0x3F に3byte、"9A:TXS(SP=X)"に1byte、"48:PHA"に1byte、0x5C-0x6Fが使用不能文字なので"60:RTS"を含んでいるアドレスにジャンプするために"4C:JMP $****"で3byte、合計8byteが必要になります。 残念なことに1byte足りないので無理やり捻出する事を考えます。 "48:PHA"からはじまり"60:RTS"で終わるサブルーチンがあれば1byteを削減できるので、探した結果ふたつの名前が候補に上がりました。 4人目の名前は「ちごあゆ」か「ちごにむ」のどちらかが使え、入力が楽なのは前者ですがムービーの最後に入力が余計に必要になるのでTASには向きません。 2人目の名前には "AF:LAX $****" という illegal opcode を使います、これにより37*2種類の候補の名前からカーソル移動の一番少ないものを選択できます。 「よるえき」という文字がカーソル移動10回で済むので、多分これが一番早いと思います。

ここで注意が必要なのは、4人目の職業が赤魔道士[03]の場合Aの値が$010Bの値とAの論理和になるが、$010Bはエミュレータの初期化パターンによって#$00になっている。 $010Bの初期値はコンソールによって個体差があるので白魔道士[04]でなければ成功しない事がある。

So, the run has been taken down. Where's the pastebin again?
