HOSTILEFUN'S PROFILE

I've been reverse engineering some old dos and pc-98 games for modern use. However, I can not seem to figure out a way of extracting the graphics. I believe they are stored in a .GRA format, a format I have never seen before. Can anyone help?

I came to wonder one day, whether or not if short games ( More compact interest, but loss of playtime and typically more gameplay.) were better then longer games (More story, and more features at the loss of compact interest). While working on my main project, I began to create a minigame called "Digital Knight Syndrome", just because the idea crossed my mind, where I suddenly realized that in itself, it is a mini-rpg. So that brings me to the present, does the length of a game change its value in your minds if it is longer or shorter?
