THIS I can help with...(posted 9289 days ago)My 869k Dangun Feveron recording is legit. You just have to delete dfeveron.nv from the NVRAM directory prior to playback.
Dangun Feveron's scoring system is strange - it relies heavily on you picking up the enemy hostages after you destroy them from your ships. Each successive one builds the point multiplier. First you get 1 extra point, then 2, then 3, etc. This controls both the number of points you get for picking one up, and the number of points awarded for shooting an enemy. If you have the multiplier up to 150, then you let an enemy hostage slip away, it resets to 1. So then you're earning a LOT less points. You have to make sure you get every one that comes along and not let any slip by if you want a higher score.
I had about 140k at the end of level 1 and an additional 650k on level 2.
