I disassemble old video games (mostly MS-DOS).
I decompile them when possible.

J'ai prévu de faire un live youtube le 29 mars à 10 heures du matin. Désolé pour la grasse mat. Mais vous pourrez toujours regarder en mangeant vos croissants.
Le sujet ? Décompilation du jeu Supercopter pour msdos.

Hello @nicole.express, it seems that you possess a real Tandy 1000. I am not very familiar with the hardware but I happen to have reversed an old MSDOS game (Ultima IV) which uses some strange keyboard scancodes. I believe they are for Tandy 1000 but I cannot find documentation to assert this. help?

I found an intriguing piece of code in the executable EXODUS.COM from the MSDOS version of the game "EXODUS:Ultima Ⅲ".
It starts at offset $73F0 (when loaded in memory):
xxxx:73F0 B42C MOV AH,2C
xxxx:73F2 CD15 INT 15
It took me some time to understand that it was a mistake from the programmer.🧵
