I don't do any support for the B2S version which was a temporary version, the backglass is temporary, the script was modified to work with the B2S system, there are some graphic issues if you play it with vp9.14 and the gameplay is different.
The last version 1.05 was done to work fine with vp9.14 and the new directB2s system. I added more strength to the flippers and it's now easier to reach any points of the table.... Except for the cannon unfortunately, I know it's pretty hard to hit this point (even if you can do it with the right flipper when you get used to it) 
I will take a look at this when I have a moment, it's hard because I don't want to break the current gameplay, which is a fragile balance.
To newer:
- I think you didn't activated the "antialias ball" and it's why the reflection looked crappy. When you disable the relfection, you remove the ball shadow at the same time, and in in my opinion you lose an important feature.
- Je pense que tu n'as pas activé le "antialias ball" dans les options et c'est pourquoi la réflexion te parait moche. Quand tu la vires, le problème c'est que tu vires aussi l'ombre de la balle et personnellement, je trouve ça super plat au niveau du visuel.
- Pienso que no has activado el "antialias ball" en las opciones y es la razon porque el reflejo te parece feo. Cuando lo quitas, el problema es que quitas tambien la sombra de la bala y a mi me parece aun mas feo porque la bala parece plana.
