Tap normal mode counterstops

Was wondering if you could counterstop Tap's normal mode so went for a try with Mame using cheat (only I pieces) and... the game counterstops at 999 999

However, it's clearly impossible to do it without cheating, even TASed since it needs like tetris to tetris to tetris to tetris combos ending with bravos from the beginning to the end

Wondering what score you could reach Tasing the game ?

 

Cheating with all O pieces instead would give you a ballpark figure.
