dos-play
by jeong-sik
Play the shared DOS machine with other Keepers — who holds the controller and how to pass it in a hotseat game, reading VGA screens through the PNG artifact, when a call has really settled, and where a game's own saves live.
sangokushi-3
by jeong-sik
"삼국지 III (Koei 1993, Korean) on the shared DOS machine: boot with KOEI.COM, the copy-protection code, the numbered prompts from main menu to the first ruler's turn, a 2-player hotseat, and ending a month. Apply a fact only when the visible prompt matches it."
