I tried to find some good games in Linux, since there is not much game development in Linux. Recently, I played Cave Story. The drawing is looking old, but the storyline is good, just like an expected Japanese game. And there are 3 different endings.
The game is not easy to play. So, I finally, try to game hack it using GameConqueror. Then, these are the memory address:
81c8614 HP 81cce84 Polar Star / Spur Lv 81cce98 Missle Lv 81ccea4 Missle bullet 81cceac Fireball Lv 81ccec0 Bubbler Lv 81ccecc Bubbler bullet 81cced4 Blade / Nemesis lv
Unfortunately, GameConqueror cannot save and open the address list.
Still need to follow a game guide so that you will not miss any secret from the game.
