Restoring EcoQuest 2's debug functionality

[bugmenot]

Both Sluicebox' eco2 and EricOakford' eco2demo have debug scripts but it seems they're just like the game's built-in 98.scr and 98.hep files which do nothing but an initial WhereTo? dialog at boot (whereas leaving the room or doing any actions gets the game stuck!).
That was also the case with QFG1VGA and QFG3, yet EricOakford somehow managed to restore their full debug functionality on his own. Since both archives might never get another update, can anyone here do the same here like what was done with QFG1VGA and QFG3?
