I'm using a DOS memory scaning/hacking program called "FPE(Fix People Expert)", like "Game Wizard".
It's a TSR program for cheating in DOS games by Taiwanese programmer.

The FPE's version is "2000 for DOS 1.0".
(Free for FPE 2000[Windows 9x version of FPE] user and I own it, I can't using older version of FPE[v5.0 for DOS] because it'll become "uninstalled" when every time I run DOSBox, even I installed it, quit DOSBox, run DOSBox, it says "not installed, please reinstall".)

It works fine in DOSBox. But I found a bug cause I cannot input anythings to DOSBox(but some DOSBox functions still work like Mapper) after I tried unload it from memory with its remove function.

If I go to its setup program(FPESETUP.EXE), turn on the "RESET 8259" function, save and quit, call fpe, un-TSR by using "fpe r", and I cannot input anything after I un-TSR it.
(Rerun DOSBox, turn that off, call fpe then remove it, it's fine.)

I uploaded a DOSBox AVI movie to show(in attachment).

Tried 0.70/0.73/0.74, both happens.

I know it's not a GAME program, but it's a program that using cheat/research/for fun on DOS games... :p
