OK, Tyrian 2000 GB IS complete. However, it DOES call for a hacking/modding. If anyonoe here is a residing member in romhacking.net, they could go and ask for some help on this. My proposal for a hack of this game is: 1. Addition of a new main menu option: Help. Purpose: to make it easier for new players to understand what each thing does and how they works. 2. Restoration of SP Weapons. They might be coded in it or not. Who knows? 3. Warp fix. The stage's boss spams too many projectiles, most of the time rendering your own weapons partially useless. 4. Addition of new weapons. Some new weapons could be added or replace some existing ones. 5. Exclusion of Engine/Energy use in Arcade, Super Arcade and Challenge. 6. Addition of "loop" system. You know you'll never get X or Y weapon early in the game, no matter how hard you try to earn cash for it. 7. More stages. I know you want to beat a floating nose too!
Lastly, info on the screenshot. It is a proof that I somehow unlocked ONE item out of, I think, 53 items. How I did? I know not. Sheer luck, apparently. And this was in my cheated save data.
