The Lamp bug
---
There is a bug in the Altair 8800 version where the player will always die
after 60 turns because the lamp is not detected when darkness falls. It is
caused by two erroneous upper-case "L" characters in the word "Lamp" in the
game COM file. They need to be converted to lower case to correct the bug.
Fortunately, it can easily be patched from the Altair 8800 CP/M command line,
using the standard SID command (Symbolic Instruction Debugger), before playing
the game as follows. The below sequence is to change the two bytes at memory
locations 2372 and 2377 (hex) from 4C "L" to 6C "l". (The file is loaded in RAM
at 0100 hex), and then save a fixed copy of the COM file.

Please see the accompanying YouTube video
"Abandoned Farmhouse Adventure (Altair 8800) walkthrough"
for clarity on entering this patch sequence.
This will save a patched file FARMHOU2.COM, while keeping the original
FARMHOUS.COM file intact. In fact the original GitHub release calls the CP/M
executable ADVEN.COM, but I renamed it to FARMHOUS.COM on my system to avoid
confusion with games called "Adventure".
Just run the patched version from the CP/M prompt by typing FARMHOU2.
Alternatively, using any hex editor, change the bytes at hex offsets 2272 and
2277 in FARMHOUS.COM from 4C to 6C, i.e. "L" to "l".
The lamp will then work normally when lit.
Note: the above patches have been tested on the game executable of 14,720
(decimal) bytes in length from Jeff Tranter's GitHub site (8080 section),
original filename ADVEN.COM (game version 0.9).
If you have a recompiled or different version, then the file offsets may
differ.
