I´m sure quite a few shmups on Neo at least have slowdown sometimes. If that is due to hitting sprite limits or cpu speed, Im not sure.
In any case. My Xyx arrived yesterday and I am mostly impressed about how fluid the framerate stays at all times even though it seems theres more stuff flying on the screen constantly than on any other Neo shmup that I have played. They have managed this aspect of the game extremely well. I imagine there must have been a lot of tweaking to make it run so perfect.
I totally understand why a few people mentioned Truxton. It´s like an up-tempo modernized version of it. I am only missing weapon upgrades quite a bit. I love to upgrade stuff and not having that makes the game feel a bit less rewarding than I would like in some ways. Chaining mechanism alone cant replace good weapon upgrades.
Few things I noticed that may be specific to version that I´m playing with and the cmvs with 3.0 unibios.
By default, it seems arcade mode is tate and console mode is horizontal.
In arcade mode I can not add credits.
There is no "initial settings screen" that the instructions speak about. No way to access such screen at least. There is soft dip settings menu and I have tate selected there but the console mode still goes to horizontal mode. :O
So, in arcade mode I can not play due to no credits and the console mode isn´t in tate mode for some reason.
So how to play tate with this cmvs then?
1. Turn off cmvs.
2. Press and hold buttons A,B,C and turn power on.
3. Choose japan and console modes. in region setup Exit. (by pressing A,A,B,C)
4. Power the system off once again.
5. Press and hold button A on the controller.
6. Power the system on while keeping A pressed.
7. Keep button A held until NGDEV logo appears.
8. Game is now playing in tate mode and has 8 credits to play with.
-However, after each game over, the game will revert back to horizontal mode, so repeat steps 4 to 8.
