You can save the change permanently in emulator (only for some particular emulators) by searching for "6A 08 50 8D 4E 40 E8 03 F9 FF" in executable file and change the 08 to 01.
您可以通过在可执行文件中搜索“6A 08 50 8D 4E 40 E8 03 F9 FF”并将08更改为01,将更改永久保存在模拟器中(仅适用于某些特定仿真器)。
@yzhang37 I need to do a lot of disassemble of the emulator, which seems to not worth explaining here. Moreover I forgot most of them.
Anyway I suppose you recently use that method to make the fx 500ES & 370ES emulator? (but what's the password?)
Note that I'm not often on this cncalc.org forum.
