it's been a long time ago that i've been logged in here.
A few years ago, i started a topic to fix an old game, called DIGGER to run on an old machine with Hercules Graphic Card, using CGA Emulation.
ripsaw8080 helped me to fix that by using a hex editor.
Digger and Hercules Graphic, using CGA Emulation
Now, my Hardware has changed to a plain 386 Desktop PC, using a standard VGA Card.
Most of the games from my childhood working fine 😀
Some games need MOSLO to work correctly (i even purchased the latest Moslo Deluxe from the official website) and it works really fine 😀
But there is a small thing that don't like on CASTLE ADVENTURE from Kevin Bales.
When i was a kid, this was one of the very first games i played on a real IBM XT 5160, using a plain HERCULES Card, without any CGA Emulation.
The game was displayd in 80 column mode (half display on the left) and somehow i liked that mode.
Nowadays, on CGA (and above) cards, the game will displayed in standard 40 columns (fullscreen with "streched" symbols)
Also i miss the typical green color from that Monitor... the screen is typical b/w in VGA Monitors.
Is there any chance to hack/modify the EXE file to force the game to 80 columns and green (or maybe amber) color in VGA?
The game itself has only one "color" (standard textmode)
I dont have any experience to do this on my own, but may be someone can give me a hint (maybe by using a hex editor or something)
EDIT: sorry for my bad english 😢
