Prehistorik mystery
Posted: Thu Dec 26, 2024 9:20 am
I have ported prehistorik 1 to C++ and javascript and noticed strange thing. If you set memory location 1f86:8b94 to nonzero value, it will display a "mouse" cursor which is controlled by arrow keys. Any clue what this could be?
In dos box (you need to unpack the game first with UNP.EXE or download unpacked binary here):
**debug historik**
**bp 0a34:16bb**
**sm 1f86:8b94 1**
Or press M during game (it will only show the cursor, movement doesn't work here because the interrupt emulation where the cursor position is updated is ignored):
