hahahahah 2 days and I've counter stopped it. The secret score orbs are BROKEN. They are the things that give you heaps of score as long as you are touching them, I've found one in the Valley and Station stages now. The thing is, the area that the one is in in the station has a big time limit, so you can just sit on it and just respawn when you die from the time out and milk it again and reach 999,999,990.
I think there might be a chinese revision of the game that goes into the billions of score but I'm not sure yet. If there is I'm gonna have to seek out that cart, because the combo system of the game is the fuckn funnest thing.
I'm still trying to fully combo an entire stage... I'm wondering if maybe its possible to counter stop it just from doing this. My highest is about 500 hits on the Valley stage, but if I manage to link the combo to the second area and then milk the boss for like another 1000 hits then the score increase would be crazy considering it seems very similar to dodonpachi.
And holy shit the graphics are unbelievable, especially the snow stage. Totally on par with Metal Slug.
If anyone is interested with score battle on the Japanese version, maybe we can just ban the secret orbs.
