tetris attack, flickering in 1 player stage clear mode #55

n Tetris Attack, in 1 Player Stage Clear mode, there is a wild flickering while you play, it’s strange, ’cause some foreground elements stay normal, while the background and other parts flicker. Only happens in this 1 Player Stage Clear.

All other modes look fine.

It’s reproducible.

I don’t have a real Tetris Attack cart to compare.

Seems strange, this is the only game I’ve play on SD2SNES that has weird flicker issues.

I'm using this firmware: Firmware v0.1.7 preview 3

Thanks for reporting. I'm quite sure it is caused by the IRQ hook routines for in-game buttons and cheats. I'm going to publish a less invasive version shortly which should improve it. Ultimately some games won't like the hook routines at all so I will make an option to disable them. Meanwhile they can be disabled by pressing L+R+Start+Y at runtime (at least 10 seconds into the game).

It is because of the in game routines. I've been only able to play it by using an older firmware or disabling the in game routines.

Cannot be ultimately fixed as long as the in-game routines are in place. v0.1.7 will have an option to disable them by default.

Menu option to disable in-game hooks has been implemented in 10e9429 and 926673e.
